CR3 to JPG converter
Convert Canon CR3 files to JPG at full resolution, on your own device.
CR3 replaced CR2 from the EOS M50 and EOS R onward. It uses a different container format and compresses more efficiently, which is why older software often cannot open it.
Nothing here is uploaded. CR3 files routinely run from 20 to 80 MB, which is exactly the size that upload-based converters reject or throttle. Invo reads the file straight from your disk in the browser, so size is not a constraint.
How it works
Your Canon camera writes a full JPEG preview inside every CR3 file — that is what the rear screen shows you. Invo locates it in the file's directory structure and extracts it directly, usually at full sensor resolution and in under a millisecond.
At 100% quality those original bytes are handed straight to you, so there is no re-encoding and no quality loss whatsoever. If the file has no usable preview, Invo falls back to a full LibRaw decode with your camera's recorded white balance.
When to convert, and when not to
Convert to JPG for sharing, uploading, printing through a lab, or sending client selections. Keep the CR3 as your negative — it holds the highlight and shadow latitude that makes serious editing possible, and a JPEG has already discarded it.
Need a smaller file afterwards? Compress it or resize it.
Questions
Can I open CR3 files without Photoshop or Lightroom?
Yes. This page converts CR3 to JPG in your browser with nothing to install.
Is there a size limit for CR3 files?
No. Files are read locally rather than uploaded, so even a 100 MB file is fine.
Will the JPG be full resolution?
In almost all cases. Canon embeds a full-resolution preview in CR3 files. Where a camera embeds only a small preview, Invo performs a complete decode instead.
Does converting lose quality?
At 100% quality the camera's own JPEG is copied byte for byte, so no. Lower settings re-encode and trade some quality for size.
Are my CR3 files uploaded?
No. Everything happens in your browser.
