Need help?How to Convert CRW to JPG Online
- Upload Your CRW Files: Drag and drop one or many .crw files (and any companion .thm thumbnails — they're harmless if included). Batch is supported, so you can drop a whole shoot from a Canon EOS D30, D60, 10D, 300D, or PowerShot G/Pro/S folder at once.
- Pick a Quality Preset: "Very High" is the recommended default. Choose "Highest" for archival prints, "High" or "Medium" for web galleries, or "Low / Very Low / Lowest" only when you need very small files for messaging or thumbnails.
- Resize (Optional): Keep original resolution, scale by percentage (1–100%), pick a preset (4320p down to 144p), or enter a custom Width × Height. Aspect ratio is preserved when you fill only one dimension.
- Convert and Download: Click Convert. Files process in your browser session — no sign-up, no watermark, no Adobe license required to render the legacy CIFF data inside.
Why Convert CRW to JPG?
CRW is Canon's first digital-camera RAW format, written in the Camera Image File Format (CIFF) container Canon published in 1997. It carried unprocessed sensor data from Canon's earliest DSLRs and prosumer compacts between roughly 2000 and 2004 before being superseded by the TIFF-based CR2. Two decades later, those .crw files are still on hard drives, SD cards, and CD-Rs — but the software that reads them keeps shrinking. Converting to JPG turns them back into something every phone, browser, and print kiosk can open.
- Old shoots from 2000–2004 Canon bodies — EOS D30 (2000), D60 (2002), 10D (2003), 300D / Digital Rebel (2003), PowerShot Pro1, G1–G6, and S30–S70 wrote CRW. JPGs from those files are immediately viewable in Photos, Preview, Google Photos, and any browser.
- Apps that no longer ship CRW decoders — Modern Lightroom, Photoshop, and Capture One still read CRW via Adobe Camera Raw / DNG Converter, but mobile apps, Windows Photos, macOS Quick Look thumbnails, and most cloud galleries can't. JPG bypasses the decoder problem entirely.
- Email, messaging, and social uploads — A 6–8 MB CRW from a 6 MP DSLR won't preview in Gmail, iMessage, WhatsApp, Instagram, or Facebook. A "High" quality JPG of the same image lands around 1–2 MB and previews everywhere.
- Photo lab and online print services — Shutterfly, Snapfish, Walgreens, Mpix, and Costco Photo all require JPG (or sometimes TIFF). They will reject a .crw upload outright.
- Long-term archives — CRW reading depends on a small number of libraries (libopenraw, dcraw, ExifTool, Canon DPP). JPG is an ISO/IEC 10918 standard that will be readable for decades. Convert once, archive both, lose nothing.
- Genealogy and family history projects — Scanning old family photos with an early-2000s Canon left many people with stacks of CRW files they can no longer open. JPG copies make sharing with relatives possible again.

CRW vs JPG — What the Conversion Actually Changes
| Property | CRW (input) | JPG (output) |
|---|---|---|
| Pixel data | Linear sensor RAW (10–12 bit) | 8-bit per channel, processed |
| Typical size (6 MP) | ~6–8 MB | ~1–2 MB at "Very High" |
| White balance / exposure | Adjustable post-capture | Baked in |
| Universal viewer support | No | Yes (every OS, every browser) |
| EXIF metadata | Preserved | Preserved (when "Highest"/"Very High") |
| Lossless | Yes | No (DCT-quantised) |
Quality Preset Quick Guide
| Preset | Approx JPEG quality | Best for |
|---|---|---|
| Highest | ~95–100 | Archival, large prints, before further editing |
| Very High (default) | ~85–90 | Photo libraries, family albums, general use |
| High | ~75–80 | Web galleries, blog posts |
| Medium | ~60–70 | Email attachments, messaging |
| Low / Very Low / Lowest | ≤50 | Thumbnails, contact sheets only |
Frequently Asked Questions
Which Canon cameras actually wrote CRW files?
CRW shipped with Canon's first DSLRs and the matching prosumer compacts of the era: EOS D30 (2000), D60 (2002), 10D (2003), and 300D / Digital Rebel (2003), plus the PowerShot Pro1, G1, G2, G3, G5, G6, and the S30, S40, S45, S50, S60, S70. With the EOS-1D Mark II in 2004 Canon switched to the TIFF-based CR2 format. See the exiftool CRW reference for the full model list.
Why won't my modern phone or photo app open a .crw file?
CRW uses the CIFF container, which almost no consumer software ships with anymore. Windows Photos, macOS Photos, iOS Photos, Google Photos, and the gallery apps on Android phones don't include a CIFF decoder. Adobe Camera Raw, Canon's Digital Photo Professional, RawTherapee, darktable, and ExifTool still read CRW, but those are desktop pro tools — not the casual viewers most people use. Converting to JPG is the simplest fix.
What's the difference between a CRW file and the .thm next to it?
The .crw is the raw sensor capture; the .thm is a small JPEG preview plus EXIF metadata that the camera wrote alongside it so the in-camera review screen could show a thumbnail without decoding the RAW. You can ignore .thm during conversion — uploading both is fine, and you can drop the .thm files after.
Will I lose detail compared to opening the CRW in Lightroom?
A bit, yes. CRW holds 10–12 bits per channel of linear sensor data, while JPG is 8 bits per channel after gamma encoding and DCT compression. For viewing, sharing, and most reprints the difference is invisible. If you plan to push exposure or white balance dramatically, edit the CRW in Lightroom or Canon Digital Photo Professional first and export the JPG from there. For archival, converting to TIFF or PNG preserves more headroom than JPG.
How big will a converted JPG be compared to the original CRW?
A 6 MP CRW from a 10D or 300D is typically 6–8 MB on disk. Converted at "Very High" quality, the JPG usually lands at 1–2 MB — about a 75–85% reduction with no perceptible quality loss for normal viewing. "Highest" produces 2–4 MB JPGs that retain almost all visible detail. "Lowest" can drop below 200 KB but introduces visible blocking.
Do I need Adobe Camera Raw or DNG Converter installed?
No. xconvert decodes CRW server-side (or in-browser, depending on your file size) — your machine doesn't need any RAW software. If you separately want to keep an editable copy, Adobe's free DNG Converter can transcode CRW to the open DNG format, which most modern editors still accept.
Can I batch-convert a whole shoot at once?
Yes. Drop multiple CRW files in one go and they'll all be converted with the same Quality Preset and resolution settings. This is the usual workflow for archive migrations — point at a folder, pick "Very High", convert, download a zip.
Is CRW the same thing as Canon's "RAW" or "C-RAW"?
No. "Canon RAW" is a marketing umbrella that covers three different formats: CRW (CIFF, 2000–2004), CR2 (TIFF-based, 2004–2018), and CR3 (ISO BMFF, 2018–present). "C-RAW" is a lossy compression option inside the CR3 container introduced with the EOS M50 — it's not a separate file format and never applied to CRW.
After converting, can I re-edit the JPGs the way I would a RAW?
Only within JPG's tighter limits. Recoverable highlight and shadow detail beyond what's already visible in the JPG is gone after the RAW develop. Small edits — crop, resize, compress further, straighten, light tonal tweaks — work fine. For aggressive recovery you'll want to keep the original CRW files and re-develop them in a RAW editor.
