Add your CR2 file
Drop one or more .cr2 files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Developing a .cr2 camera file into .jpg turns unprocessed sensor data into a finished image any app can open. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Developing a .cr2 camera file into .jpg turns unprocessed sensor data into a finished image any app can open. A .cr2 file is a Canon RAW photograph, the second-generation format Canon's DSLRs wrote from 2004 until the switch to CR3 in 2018. It records the sensor's mosaiced readout before white balance, sharpening, or color rendering are baked in, giving full latitude to reprocess the shot later.
A .jpg file is a photograph or other continuous-tone image compressed with the JPEG standard, the most widely used image codec ever shipped. Nearly every camera, phone, and website produces or accepts .jpg files, which makes it the default interchange format for photos. For this route the practical draw is opens everywhere, from 1990s software to the newest phone and excellent size-to-quality ratio for photographic content — balanced against every re-save re-compresses the image, so quality erodes across editing generations, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .cr2, files run 20-40 MB where a JPEG would be a few megabytes. Switching to .jpg buys you opens everywhere, from 1990s software to the newest phone, which is why it is the better fit for publishing photographs on websites where file size and universal support matter. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | Canon RAW 2 (.cr2) | JPEG image (.jpg) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossy — discards detail it judges invisible to shrink files |
| How it stores data | tIFF container with multiple IFDs holding the raw sensor image and several embedded JPEG previews | compresses 8x8 pixel blocks with a discrete cosine transform followed by quantization, which is where detail is discarded |
| Strongest at | developing photos from Canon DSLRs with full exposure and white-balance latitude | publishing photographs on websites where file size and universal support matter |
| Weak spot | files run 20-40 MB where a JPEG would be a few megabytes | every re-save re-compresses the image, so quality erodes across editing generations |
| Metadata | full EXIF including lens and exposure data, extensive Canon MakerNotes, and XMP sidecar or embedded metadata are all standard; MakerNotes hold camera-specific details generic tools may not parse | carries EXIF (camera settings, GPS, orientation), XMP, and IPTC records in APPn marker segments, plus embedded ICC color profiles and thumbnails |

Select .jpg in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if JPG is selectable, the route is real and validated.
Press Convert. A LibRaw WebAssembly decoder demosaics the sensor data in your browser and renders a developed image ready for export.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid JPG file. Outputs keep the original filename with the .jpg extension.
Some. Since cr2 is lossless-oriented and jpg is lossy-oriented, the encoder will discard detail it judges least visible; the quality slider controls how aggressive that is. Keep the original .cr2 if you may need a pristine master later.
Yes — the .cr2 file is processed inside your browser tab and never uploaded. A LibRaw WebAssembly decoder demosaics the sensor data in your browser and renders a developed image ready for export. Close the tab and the file is gone from memory.
JPEG is supported by every mainstream operating system, browser, image editor, and printer driver in use today. It decodes natively on iOS, Android, Windows, macOS, and Linux without any add-on codecs, and every browser has rendered it since the format reached the web in the 1990s.
Smaller, usually dramatically so — that is the main reason this route exists. The quality slider trades size against fidelity; the default sits at the point where most people cannot spot the difference.
In .cr2, full EXIF including lens and exposure data, extensive Canon MakerNotes, and XMP sidecar or embedded metadata are all standard; MakerNotes hold camera-specific details generic tools may not parse. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
