How to Convert RAW Images to JPEG on Any Device

How to convert RAW images to JPEG on Windows, Mac, and iPhone, plus free Canon, Nikon, and Sony software for batch exports, and what the JPEG loses.

By Mike Wiberg · · 14 min read

To convert RAW images to JPEG, open the file in photo software and export a copy: File then Export in Adobe Lightroom, or File then Export in Preview on a Mac. Every method on this page is a version of that one step. Knowing how to convert RAW images to JPEG matters because a RAW file is not really a standard image yet, and most tools, including the browser compressor on this site, will not read it directly.

That trips people up, because almost any other image tool takes almost any image file. RAW is different. It is closer to the raw readout from your camera's sensor than to a finished photo, and every camera maker stores that readout its own way. Software has to develop it into something a browser, a printer, or an upload form can use, and that development step is the conversion this guide walks through. For what your RAW becomes once it is a JPEG, and why that format compresses the way it does, see the JPEG guide.

What Is a RAW File, and Why Can't You Upload It?

A RAW file is the unprocessed data straight off your camera's sensor, and you cannot upload it to most sites because it is large, non-standard, and not yet a finished image. Wikipedia calls RAW a "digital negative," and the name fits: it holds everything the sensor recorded, at 12 or 14 bits per channel, waiting for you to make the processing decisions the camera would otherwise make for you (Wikipedia, Raw image format).

There is also no single RAW format. Canon, Nikon, Sony, and the rest each use their own proprietary, often undocumented structure, and some change it from one camera model to the next. Adobe puts the practical problem plainly: RAW files are not standardized, so some software cannot read the files from certain cameras (Adobe, What is a RAW file). A JPEG opens in nearly anything ever built to show an image. A RAW file opens only in software taught to read that exact camera.

Why RAW Files Are Too Big to Share

The other reason to convert is size. A RAW file records one value for every photosite on the sensor at the sensor's full bit depth, so the file scales directly with the megapixel count. Here is the arithmetic for a 14-bit sensor, pixels times 14 bits divided by 8 to get bytes:

Camera resolution RAW sensor data (14-bit)
12 MP About 21 MB
24 MP About 42 MB
45 MP About 79 MB
61 MP About 107 MB
One frame of RAW, by sensor resolution uncompressed 14-bit sensor data, before in-camera compression 25 MB free upload cap 12 MP 21 MB 24 MP 42 MB 45 MP 79 MB 61 MP 107 MB Pixels times 14 bits divided by 8. Bar length proportional to bytes.

Those are the uncompressed sensor-data figures. Real RAW files run somewhat smaller because most cameras apply lossless compression, but they stay far larger than the JPEG the same shot becomes, and they routinely blow past limits a JPEG sails under. The free tier on this site caps uploads at 25 MB per image, so a 24 megapixel RAW may not fit at all, on top of the tool not reading RAW in the first place. Export to JPEG and that size problem mostly disappears.

Common RAW File Extensions

Every RAW file carries a maker-specific extension. The common ones:

  • Canon: .cr2, .cr3
  • Nikon: .nef
  • Sony: .arw
  • Fujifilm: .raf
  • Olympus and OM System: .orf
  • Adobe's universal RAW: .dng

If your file ends in one of these, it is RAW, and it needs the export step below before anything will treat it as a normal photo.

Does Converting RAW to JPEG Lose Quality?

Yes and no. Converting bakes in your edits and drops the extra editing headroom RAW carries, but a high-quality JPEG still looks the same as the RAW at normal viewing size. What you give up is latitude, not visible sharpness.

A RAW file holds 12 or 14 bits of tonal data per channel; a JPEG holds 8. That matters the moment you push an exposure hard: pulling a JPEG's shadows or highlights aggressively can show banding or posterization because of the limited color and tonal range of an 8-bit file (Adobe, RAW vs JPEG). At normal edits and normal viewing, you will not see a difference between a quality 90 JPEG and its RAW.

Keep the RAW, Not Just the JPEG

Exporting is non-destructive: it creates a brand new file and never changes the data in your RAW. So converting costs you nothing as long as you keep the original. Think of the JPEG as a shareable print and the RAW as the negative it came from. Delete the RAW and you throw away the only copy of the sensor's full data, the copy that lets you recover a blown sky or a crushed shadow later.

How to Convert RAW Images to JPEG Without Special Software

You can convert RAW images to JPEG without buying anything, using the tools already on your computer or phone. The Photos app on Windows, Preview on a Mac, and the Files app on an iPhone each export a single RAW to JPEG in a few clicks.

Method Device Batches many files?
Photos, Save as Windows No, one at a time
Preview, Export Mac Yes, multi-select
Files, Quick Actions iPhone No, one at a time
Maker software Windows or Mac Yes

On Windows (Photos App)

Windows needs one free add-on before it will even preview most RAW files: the Raw Image Extension from the Microsoft Store, which teaches the Photos app to read formats like CR3 and ARW. Once it is installed, open the RAW in Photos, use the three-dot menu, choose Save as, and pick JPG. Photos converts one file at a time this way, so for a whole card of shots, use maker software or Lightroom below.

On a Mac (Preview)

To convert RAW photos to JPEG on Mac, open the file in Preview, choose File then Export, set Format to JPEG, drag the Quality slider, and Save (Apple, Convert image file types in Preview). Preview reads a lot of common RAW formats on its own, and it batches: select several RAW files in Finder, open them together, then export the whole set at once. It will not open a brand new camera's format until macOS adds the codec, which a system update usually handles.

On an iPhone (Files App)

If a RAW shot is already on your iPhone, save it into the Files app, touch and hold the file, tap Quick Actions, then Convert Image, and choose JPEG. It handles one image at a time, which is fine for the occasional shot and slow for a shoot. iPhones only produce RAW when you turn on Apple ProRAW or a third-party camera app, so most people never need this until they do.

Convert RAW to JPEG in Lightroom Classic

Lightroom Classic is the standard route for anyone shooting RAW regularly, and it gives you the most control over the JPEG on the way out. To convert RAW images to JPEG in Lightroom, you export rather than save as:

  1. Select the RAW photo or photos, then File then Export. Lightroom exports to your hard disk by default (Adobe, Export files to disk or CD).
  2. In File Settings, set Image Format to JPEG.
  3. Set Quality from 0 to 100. JPEG uses lossy compression, discarding data to make the file smaller, so a higher number keeps more detail at a larger size.
  4. Set Color Space to sRGB for the web, and use Limit File Size To if you need a hard cap.
  5. In Image Sizing, use Resize to Fit with a long-edge value to make a JPEG smaller than full resolution.
  6. Click Export. Presets like For Email set a small size and a low resolution for you.

Choosing a Quality Setting

Quality 80 to 90 suits a JPEG you may edit or print again, since it keeps most of what the RAW held. For a quick web copy or an email attachment, 60 to 75 usually looks identical at normal zoom and saves real space. The Limit File Size To field is the fastest way to hit a specific number, say a 5 MB upload cap, without guessing at the slider, and Lightroom exports a whole selection in one pass, so it doubles as your batch tool.

Convert RAW to JPEG With Free Camera Maker Software

Every major camera maker gives away software that opens its own RAW files and batch-exports them to JPEG, with no Adobe subscription required. This is the route the camera forums point to, and it is free.

RAW file Camera brand Free first-party software
.cr2, .cr3 Canon Digital Photo Professional
.nef Nikon NX Studio
.arw Sony Imaging Edge Desktop
.raf Fujifilm X RAW Studio
.orf Olympus, OM System OM Workspace

Each of these opens a folder of RAW files, applies the maker's own color rendering, and exports the batch to JPEG in one pass, which is exactly what a full memory card needs. DNG, Adobe's universal RAW, is the exception: because it is documented, almost any editor reads it, so you rarely need brand-specific software for a DNG. If you are not sure which app matches your camera, the extension on the file tells you: match the row above to the letters after the dot.

How Do You Convert RAW to JPEG Without Adobe?

You do not need Adobe at all. Free, open-source editors like Darktable and RawTherapee read most RAW formats and export JPEG, and they are the tools photographers on forums like r/photography most often recommend for a free, cross-brand workflow. Both run on Windows, Mac, and Linux. You import the RAW, adjust exposure and color if you want to, then export to JPEG at a quality you choose, the same develop-then-export idea Lightroom uses. GIMP, the free editor many people already have, opens RAW files too once Darktable or RawTherapee is installed alongside it, because it hands the RAW off to one of them to develop before you export the JPEG.

There are also online options. Search and you will find a free raw to jpg converter on half a dozen sites, and they work for a one-off file. The tradeoff is that you are uploading the full sensor data of your photo, GPS location and all, to a stranger's server, so keep private shots on a local tool instead. The browser compressor on this site deliberately does not accept RAW; it reads JPG, PNG, WebP, and AVIF, so it fits in after you have exported, not before.

Should You Shoot RAW Plus JPEG Instead?

If your camera offers a RAW plus JPEG mode, turning it on skips the conversion entirely. The camera writes an editable RAW and a ready-to-share JPEG for every shot, so you get the negative and the print in one press of the shutter. It costs storage, since you are saving two files instead of one, but a memory card is cheap and the JPEG is small next to the RAW, so the cost is mostly the card filling faster. It is the only approach here with zero export steps, and it is a sensible default for anyone easing into RAW who is not ready to give up JPEG's convenience.

Compress the Exported JPEG for Uploads and the Web

A JPEG exported at quality 90 is already reasonably small, but it is often still larger than an upload form or a fast-loading web page wants. That is where compression, not conversion, takes over.

Exporting at 80 to 90 in Lightroom already does most of the work, so running that file back through a compressor will not shrink it dramatically. Where it earns its place is hitting a specific target: drop the exported JPEG into the JPG compressor to land under a form's cap, or turn it into WebP for a web copy that runs 25 to 35 percent smaller than the JPEG at the same visual quality. Files up to 25 MB need no signup, EXIF metadata, the hidden camera and GPS data your phone or camera writes into the file, comes off automatically, and uploads are deleted from storage within an hour.

Mistakes to Avoid When Converting RAW Files

A few habits cause most of the trouble people run into with RAW conversion.

Do not assume converting touches the original. Export creates a new file; the RAW behind it stays exactly as the camera wrote it, no matter how many times or at what settings you export from it.

Do not assume any app opens any RAW. Formats are proprietary and often undocumented, and a camera released after your software last updated may not open until an update adds support. That is a compatibility gap, not a corrupt file.

Do not email the RAW instead of converting it. Most RAW files are too large for email outright, which is the most common reason people need this conversion at all.

Do not delete the RAW once you have the JPEG. The RAW is your only copy of the sensor's full data, and once it is gone you cannot pull detail back out of a shadow or a blown sky the JPEG already discarded.

Questions

Does converting RAW to JPEG lose quality?

You lose editing latitude, not visible quality. A JPEG is 8-bit and compressed, so pushing its exposure hard later can show banding, but a quality 90 export looks identical to the RAW at normal viewing size. Keep the RAW as your master and the conversion costs you nothing you will notice.

How do I convert RAW to JPEG in Windows?

Install the free Raw Image Extension from the Microsoft Store so the Photos app can read your RAW files. Open the RAW in Photos, click the three-dot menu, choose Save as, and pick JPG. For a folder of shots, use your camera maker's free software or Lightroom, since Photos converts one file at a time.

How do I convert RAW to JPEG without Adobe or paid software?

Use your camera maker's free app, Canon Digital Photo Professional, Nikon NX Studio, or Sony Imaging Edge, which all batch-export RAW to JPEG. Free open-source editors Darktable and RawTherapee work across every brand on Windows, Mac, and Linux. On a Mac, Preview alone exports many RAW formats to JPEG with no install at all.

What is the difference between a CR2, NEF, and ARW file?

They are all RAW files from different makers: CR2 and CR3 are Canon, NEF is Nikon, and ARW is Sony. Adobe's DNG is a maker-neutral RAW some cameras write directly. All of them hold unprocessed sensor data and all need the same export-to-JPEG step before they are shareable.

Can I upload a RAW file to your compressor?

No. The browser tool reads JPG, PNG, WebP, and AVIF, not RAW formats like CR2, NEF, or ARW. Export your RAW to JPEG first in Lightroom, Preview, or free maker software, then bring that JPEG here if you need it smaller or in a different format. Once your shot is a JPEG and you need it to fit a form or load fast on a page, [compress it here](/compress-jpg) and keep the original RAW untouched as your negative.
