What is a CR2 file and which Canon cameras make them?

CR2 is Canon's RAW image format — the unprocessed sensor data a Canon EOS camera saves instead of a finished picture. Canon DSLRs from roughly the mid-2000s through the late 2010s write CR2, including the Rebel line, the 5D and 7D families, and many others. It holds far more information than a JPG, which is why photographers shoot it and why it needs converting before most software will open it.

Why won't my CR2 files open?

Because a CR2 is raw sensor data, not a standard image, most apps and devices can't read it without Canon's Digital Photo Professional or a dedicated RAW editor. Phones, web forms, and other people's computers usually show a blank thumbnail or reject the file outright. Converting to JPG produces a universal image that opens everywhere with nothing installed.

My Canon saves CR3, not CR2 — what should I use?

Newer Canon bodies, especially recent mirrorless models, write CR3 rather than CR2. This tool is tuned for CR2; for CR3 and every other RAW format, use our RAW to JPG converter, which covers the whole RAW family including Canon CR3.

Does converting to JPG lose my Canon RAW editing latitude?

Yes, and it's worth being clear about. A CR2 lets you recover highlights, lift shadows, and reset white balance long after the shot. The JPG locks in the as-shot settings and drops that flexibility. Convert for sharing and viewing, but keep the CR2 as your master if you intend to edit — the JPG cannot be developed back into a RAW file.

Why does the JPG look different from the image on my camera?

The picture on your camera's screen is Canon's own rendering, with its picture style, contrast, and color processing applied. This conversion does a neutral baseline demosaic at the recorded white balance and exposure — there are no exposure or white-balance controls here. The result is accurate but can look slightly flatter than the in-camera preview. That's normal for a straight RAW-to-JPG decode.

How much smaller will the JPG be?

Considerably smaller. CR2 files often run twenty to fifty megabytes each, while the JPG at quality 90 typically lands in the low megabytes or less, depending on the image. That size drop is what makes the shots easy to send, upload, and store.

Can I convert a whole shoot at once?

Yes. Drop up to 50 CR2 files in a single pass, each up to 100 MB. They share one quality setting unless you override it, and they download together as a single ZIP full of .jpg files — handy for delivering or culling an entire session.

Are my CR2 files uploaded anywhere?

No. Every CR2 is demosaiced and re-encoded inside your browser using WebAssembly. Nothing is sent to a server, nothing is stored afterward, and metadata including GPS is stripped by default. You can confirm it yourself in your browser's Network tab while a conversion runs.

Why your Canon CR2 files won't open — and what JPG fixes

CR2 is Canon's RAW format, the file a Canon EOS DSLR writes straight from the sensor. If you shoot a Rebel, a 5D, a 7D, or almost any Canon body from that era, your memory card fills with .cr2 files instead of ready-made pictures. A CR2 is not really an image yet — it is a dump of raw sensor readings plus the camera's notes on white balance and exposure, waiting to be developed. That is what gives RAW its famous editing latitude, and it is also why a CR2 lands on your drive weighing twenty, thirty, sometimes fifty megabytes each.

The problem shows up the moment you leave Canon's own software. Your phone won't preview a CR2. A web upload form rejects it. A client's laptop shows a blank thumbnail and no way in. Windows and macOS may or may not render it depending on codecs, and most apps simply shrug. Canon expects you to open CR2 files in Digital Photo Professional or a full RAW editor — fine at your desk, useless when you just copied a card and want to see your shots. JPG is the opposite: every phone, browser, and program reads it instantly, and the file is a fraction of the size.

AnyResizer bridges that gap without any Canon software. It performs a baseline demosaic of each CR2 — reading the sensor data at the as-shot white balance and exposure the camera recorded — and re-encodes it as a clean JPG at quality 90. Drop one file and the JPG saves straight to your device; drop a whole shoot and they come back zipped with tidy .jpg names. Every decode and encode runs inside your browser through WebAssembly, so no file is ever uploaded, and metadata including GPS is stripped by default.

Opens where CR2 can't

CR2 needs Canon software or a RAW editor to show anything. A JPG previews on a phone, sails through an upload form, and displays on a client's machine with nothing installed.

Slashes the file size

A single CR2 can run past forty megabytes. The JPG that comes back is usually a small fraction of that — light enough to text, email, or post without a second thought.

Runs in your browser

Your Canon files never leave your machine. Open the Network tab while a batch converts and you will watch nothing get uploaded.

Where a CR2-to-JPG swap pays off

Delivering proofs to a client

Nobody wants a folder of files they can't open. Convert the shoot to JPG and the client previews every frame on their phone or laptop, no photo software required.

Files copied off an SD card

You pulled the CR2 files off the card and now they won't open on your computer. A quick convert to JPG lets you actually see the shots you took.

Uploading to a site or form

Job portals, marketplaces, and print services almost always reject CR2. Convert to JPG first and the same photo uploads without an error.

Sharing to social and chat apps

Instagram, WhatsApp, and the rest won't touch a raw Canon file. A JPG posts and shares everywhere the CR2 gets turned away.

Quick previews before the full edit

Need to cull a shoot fast? Batch the CR2 files to JPG, flip through them anywhere, and take only the keepers back into your RAW editor.

Emailing shots to a friend or editor

A CR2 blows past most attachment limits and won't preview in the message. As a JPG it sends in seconds and shows inline for whoever opens it.

Built for getting Canon shots out of CR2 and into JPG

Quality 90 by default — clean enough for proofs and delivery
Batch a whole shoot — up to 50 CR2 files in one pass
GPS and metadata stripped by default so the JPG stays lean and private
One unreadable CR2 never halts the rest of the batch

Three steps from CR2 to JPG

Add your Canon RAW files
Drag in a single CR2 straight off the card or a whole shoot of fifty. They queue together, all sharing the same settings unless you change one.
Choose your quality
Quality 90 is the default and holds detail well for delivery and proofing. Slide it lower when a smaller file matters more than the last sliver of sharpness.
Save your JPG
One file downloads on its own; a batch returns as a single ZIP, every shot carrying a fresh .jpg name.

Getting the best CR2-to-JPG results

Tip 1:
Always keep the original CR2 if you plan to edit. Converting to JPG bakes in the as-shot white balance and exposure and throws away the RAW editing latitude — you cannot get it back from the JPG.
Tip 2:
Expect the JPG to look a touch flatter than the preview on your camera's screen. That in-camera image uses Canon's picture styles and processing; this conversion is a neutral baseline demosaic, not a full RAW development.
Tip 3:
Leave quality at 90 or above for anything you will deliver or print, so fine detail and clean edges survive the encode.
Tip 4:
Shooting a newer Canon that writes CR3 instead of CR2? Use the RAW to JPG tool, which handles CR3 and other RAW formats.
