Viewing, inspecting and verifying. You get the image (or the embedded full-size preview, for camera RAW) rendered on screen. File details, exact byte size and the detected signature are always shown.
How to open a .cr2 file
If double-clicking a CR2 file did nothing useful, that is normal: the format is fine, your operating system just has no default application registered for it. This page explains the format and gives you a way to read one immediately.
What is a .cr2 file?
Canon RAW version 2 is an image format developed by Canon, first appearing in 2004. It is normally produced by Canon EOS cameras (2004-2018).
TIFF-based, with 'CR' at offset 8 as a secondary marker. Superseded by the CR3 format on newer EOS bodies.

Open a .cr2 file in your browser
OpenAnyFile routes .cr2 to its TIFF/RAW decoder, which decodes the image (or the embedded full-size preview, for camera RAW) rendered on screen.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .cr2 file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
- The extension is detected and the file is handed to the TIFF/RAW decoder.
- Your CR2 opens on its own viewer page: the image (or the embedded full-size preview, for camera RAW) rendered on screen.
- Use fullscreen for a closer look, or download the file back out unchanged. Nothing is transmitted anywhere — the parsing happens in your own browser process.
What you can and cannot do with it here
Does not work
Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.
Local-only by design, not by promise
Plenty of sites promise they delete your uploads. OpenAnyFile avoids the promise by avoiding the upload. When you drop a .cr2 file in, the browser grants the page temporary read access to those bytes and nothing more — the page has no path to send them anywhere. You can verify it in seconds: open DevTools, switch to the network tab, and open a file. The request list stays empty.
Frequently asked questions about CR2 files
Can I open a .cr2 file without installing special software?
Yes. OpenAnyFile's TIFF/RAW decoder runs in your browser, so you can read a CR2 file with nothing installed. You get the image (or the embedded full-size preview, for camera RAW) rendered on screen. For full editing you still need the original application — this is a viewer, not an editor.
How can I check a file really is a CR2 file?
Look at the first bytes rather than the extension. A genuine CR2 begins with 49 49 2A 00 .. 43 52. Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .cr2 by mistake is easy to spot.
Is it safe to open a CR2 file online?
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.
What is a .cr2 file, exactly?
Canon RAW version 2 — an image/x-canon-cr2 format created by Canon since 2004. TIFF-based, with 'CR' at offset 8 as a secondary marker. Superseded by the CR3 format on newer EOS bodies.
Does the same viewer handle formats related to CR2?
Yes — the same engine also opens .arw, .dng, .nef, so you can compare related files without switching tools.
