toolkit Canon's newer CR3 raw files convert to JPG here without an upload: add as many as you like above and the whole batch is returned as one .zip. Decoding runs entirely on your own device, so a shoot under NDA can be converted without breaking it.
What CR3 is
CR3 arrived in 2018 with the EOS M50 and is what Canon's EOS R mirrorless bodies and its later DSLRs write. Unlike the TIFF-based CR2 it replaced, CR3 is built on the same ISO media container family as MP4, which is why older raw software often cannot open it — and why it has its own decode path and its own page here.
Whole shoots, not one file at a time
A batch here is a queue you can watch and steer. Files convert in the order you added them, each showing its own progress; you can cancel one that is running, drop the rest of the queue in a single click, or retry anything that failed, all without disturbing the photos that already converted. That control is the reason batches run one file at a time rather than all at once. However many you add, it is free.
Why convert CR3 to JPG
Support for CR3 still lags in older editors, operating-system previews and most online services, so a CR3 is often a file the recipient cannot open at all. A JPG is readable everywhere and far smaller. Convert a copy for sharing and keep the CR3 for editing.
Camera rotation is applied
A CR3 records whether the camera was held vertically, while the image data itself always stays in sensor layout. That rotation is applied during conversion, so no JPG needs turning afterwards.
JPG quality options
Pick 100%, 92%, 80% or 60% before starting; the choice applies to every file queued. The default 92% keeps the detail a modern Canon sensor resolves while cutting the file to a fraction of the CR3's size.
Frequently asked questions
Is a CR3 uploaded during conversion?
No. Everything runs locally in your browser via WebAssembly; a CR3 never leaves your device, which is what makes this usable for work under NDA.
Can I convert a batch of CR3 files?
Yes, with no limit on how many. They convert in the order you added them and each one has its own progress, cancel and retry, so a single awkward file never costs you the rest of the batch. The finished photos are offered as one .zip.
Is CR3 the same format as CR2?
No — CR3 is a different, newer container. Use the dedicated CR2 to JPG page if your file is a .CR2 instead.
Why won't my CR3 files open in older software?
CR3 uses a different container and different compression from CR2, so raw software released before 2018 and not updated since cannot read it. Converting to JPG here sidesteps that, and Adobe's free DNG Converter can turn a CR3 into a DNG for an older editor.
Is JPG to CR3 possible?
No. The conversion is one-way: this site decodes CR3 but has no encoder that writes it.
Does the JPG use my Canon Picture Style?
No. A Picture Style is an instruction to Canon's own processing, not part of the sensor data. This tool develops the raw data with its own rendering, so contrast and colour can differ from the camera's JPEG, and edits saved by a separate editor are not applied.
