CR2 Converter

How to Convert CR2 to Any Format

1. Upload Your CR2 File: Drag and drop your Canon RAW photos or click "Add Files". Batch is supported — drop in a whole shoot's worth of .cr2 files and each one converts in parallel, then download them together as a ZIP.
2. Pick an Output Format and Quality Preset: Choose the target — JPG, PNG, TIFF, WebP, AVIF, HEIC, BMP, PPM, GIF, or PDF. The default Quality Preset is "Very High (Recommended)"; drop it to High, Medium, or Low to trade detail for a smaller file, or switch to Specific file size to cap output at an exact MB target. For a TIFF or PNG that keeps every edit, set Lossless to "Yes".
3. Resize, Set Bit Depth, or Choose DPI (Optional): Under Image resolution, keep original, pick a Preset Resolution (8K / 4K / 1440p / 1080p / 768p / 720p / 480p / 360p), scale by percentage, or enter a custom Width × Height with aspect ratio locked. For a TIFF or PNG archive, set Bit Depth to 16-bit to preserve the wide tonal range of the RAW capture; for print or PDF output, raise the DPI (300 for print, 600 for archival).
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert a CR2 File?

CR2 (Canon Raw version 2) is the RAW format Canon introduced around 2004 with the EOS 20D and EOS 350D (Digital Rebel XT). Built on the TIFF/EP standard, a CR2 stores the near-raw signal straight off the camera's sensor — 12-bit on early bodies and 14-bit on most later EOS DSLRs — together with the embedded JPEG preview and the full set of shooting metadata. That linear sensor data is what gives RAW its editing latitude: you can recover blown highlights, lift shadows, and reset white balance after the fact in a way a baked JPEG never allows. The catch is that almost nothing outside dedicated photo software can display a CR2 — and the format is proprietary to Canon, so it was never meant to be a sharing or delivery format. Converting turns that editing master into a file the rest of the world can actually open. Common reasons people convert a CR2:

• Sharing, uploading, or printing (JPG) — A CR2 won't upload to most websites, attach to email cleanly, or open in a basic image viewer, and a single RAW is often 20-30 MB. Converting CR2 to JPG bakes in the current exposure and white balance and produces a file a fraction of the size that opens on every phone, browser, and print kiosk. This is the most common conversion by far.
• Editing in apps that don't read RAW (PNG / TIFF) — Many editors, design tools, and document workflows can't import a Canon RAW directly. Exporting to a lossless PNG or 16-bit TIFF hands those apps a full-quality, fully-rendered image with no proprietary decoding required. A 16-bit TIFF keeps the wide tonal range for further retouching; a PNG is the right target for graphics work and transparency.
• Long-term archiving (TIFF / DNG) — Because CR2 is proprietary, archivists worry that Canon could one day drop support for old variants. A 16-bit TIFF is a stable, openly-documented master that any imaging program can read decades from now. Adobe's DNG is the open RAW-archival alternative and is typically 15-20% smaller than the original RAW while keeping the sensor data intact.
• Modern web delivery (WebP / AVIF) — For a portfolio or gallery, WebP and AVIF deliver the same visible quality as JPG at a meaningfully smaller size, which speeds up page loads. Both are supported in current Chrome, Firefox, Edge, and Safari.
• Contact sheets and proofs (PDF) — Wrapping a set of converted photos into a single PDF makes a clean proof sheet or client deliverable that opens anywhere without a gallery app. See CR2 to PDF for the multi-image flow.

What "Converting RAW" Actually Does

A CR2 is not a finished picture — it's the sensor's measurements plus instructions. When you open a RAW, software demosaics it: it reconstructs full color from the camera's Bayer color-filter grid, then applies white balance, a tone curve, and color rendering to produce a viewable image. Converting a CR2 to JPG, PNG, or TIFF runs exactly that pipeline on our servers and writes out the rendered result. That's why the conversion is one-directional in practice: a JPG or TIFF made from a CR2 is a developed photo, and you can't fully reconstruct the original RAW latitude from it afterward — keep your CR2 originals.

Two choices control how much of the RAW's quality survives. Bit depth decides tonal range: an 8-bit JPG holds 256 levels per channel, while a 16-bit TIFF or PNG preserves the smooth gradients of the 12- or 14-bit capture, which matters if you'll edit further. Compression decides file size: JPG and WebP are lossy (smaller, fine for delivery), while PNG and TIFF can be lossless (larger, ideal as a master). Pick lossy 8-bit for sharing, lossless 16-bit for archiving and re-editing.

Output Format Comparison

CR2 vs CRW vs CR3 vs DNG

If your files are .cr3 rather than .cr2, that's Canon's newer RAW from DIGIC 8 cameras (most Canon bodies since 2018) — a different format that needs its own converter. CRW is the earlier Canon RAW from the first EOS digital bodies.

Frequently Asked Questions

Does converting CR2 to JPG lose quality?

Some, but it's controllable. A CR2 holds far more tonal data than an 8-bit JPG can store, so the conversion bakes in the current exposure and white balance and discards the editing latitude you'd have kept in RAW — that part is unavoidable when you leave RAW. The visible quality, though, depends on the Quality Preset: "Very High (Recommended)" produces a JPG that's hard to tell from the rendered RAW on screen, while lower presets trade detail for a smaller file. The key habit is to keep your original .cr2 files; the JPG is a developed deliverable, not a replacement for the master.

Should I convert CR2 to TIFF or PNG to keep full quality?

Both are lossless, so pick by tonal depth and use. Choose a 16-bit TIFF when you want a print-ready or archival master that preserves the wide tonal range of the 12- or 14-bit capture for further retouching — set Lossless to "Yes" and Bit Depth to 16-bit. Choose PNG when you need the image for graphics work, screenshots, transparency, or an editor that reads PNG but not TIFF. PNG tops out where most viewers expect 8-bit, so for serious re-editing of highlights and shadows, TIFF is the safer master.

Why won't my CR2 file open or upload anywhere?

Because CR2 is a proprietary Canon RAW format, not a standard image. Most websites, email clients, basic photo viewers, and editors can't decode it without specific RAW support, and even systems that show a thumbnail (from the embedded JPEG preview) often can't display the full image. Converting to JPG or PNG turns it into a file that opens on every phone, browser, and viewer. In our testing, a 22 MB CR2 from an EOS-series body converted to a roughly 4-6 MB JPG at the "Very High" preset, openable anywhere.

What's the difference between CR2 and CR3?

CR2 (Canon Raw version 2) is the RAW format Canon used from around 2004 until 2018, built on the TIFF/EP standard. CR3 replaced it starting in 2018 with the DIGIC 8 processor: it uses the ISO Base Media File Format with Canon's crx codec and adds a lossy "C-RAW" option that's roughly 40% smaller than full RAW with little visible difference. They're different formats with different internals, so a CR2 tool and a CR3 tool aren't interchangeable. Check your file's extension — .cr2 versus .cr3 — to know which you have.

Can I batch-convert a whole CR2 photo shoot at once?

Yes. Drop in as many .cr2 files as you like and each converts in parallel with the same output format and settings, then you download them as one ZIP. This is the typical workflow for clearing a card after a shoot — convert all the keepers to JPG for a client gallery in one pass, while keeping the RAW originals on your drive. There's no fixed file-count cap; the practical limit is how long the upload of many large RAW files takes on your connection.

Is converting CR2 to DNG better for archiving than TIFF?

They solve the problem differently. DNG (Adobe Digital Negative) is an open, documented RAW container that keeps the sensor's editing latitude intact while being about 15-20% smaller than the original CR2 — a good hedge against a proprietary format losing support. A 16-bit TIFF is not RAW anymore: it's a fully-rendered, openly-documented pixel master, ideal when you've finished developing and want a stable file any imaging program will read for decades. Use DNG to preserve re-editing flexibility; use TIFF for a finished archival master.

What's the largest CR2 file I can convert?

There's no fixed per-file cap. Conversion runs on our servers, so the practical limit is your upload size and connection speed — even high-megapixel CR2 files of 30-50 MB convert routinely, and batch jobs have no quantity limit. If you're clearing a large card over a slow connection, the upload is the slow part, not the conversion; queue the batch and grab the ZIP when it finishes.
