What happens when you convert CR2 to TIFF
- The CR2 is developed by LibRaw, the open-source camera RAW decoder, on our conversion server: the sensor data is turned into a full-colour picture with the white balance the camera recorded, AHD demosaicing and standard sRGB colour.
- ImageMagick then saves it as a TIFF with lossless ZIP compression, at the camera's full resolution, 8 bits per channel. The photo is turned the way the camera was held.
- This is a neutral, straight development, much like the camera's own JPG settings switched off: no lens corrections, noise reduction or creative styles are applied, so it can look flatter than an edited version.
- This conversion runs on our server: the file is uploaded, converted, and deleted together with the result as soon as the result has been sent back to you. Nothing is kept. Files up to 25 MB are accepted.
How to convert CR2 to TIFF online
- Press "Choose CR2 files" and select one or more files, or drag them onto the box. Files up to 25 MB each can be converted.
- There are no settings to choose: the converter keeps everything the target format can hold.
- Press "Convert to TIFF". The file is uploaded to our conversion server, converted in a few seconds, and deleted together with the result as soon as the result is sent back.
- Save each TIFF with its download button. Our server has already deleted both your CR2 and the TIFF by then.
Why convert CR2 to TIFF?
CR2 files usually come from Canon EOS cameras made from 2004 to about 2018. People convert them to TIFF because TIFF is the format printers, scanners and archives trust for lossless images.
In short, CR2 is good at what it was made for, and TIFF is the more practical choice when the file has to open, upload or print somewhere else. CR2 does not open in browsers; Windows Photos (with the Raw Image Extension), macOS Photos and Preview, Lightroom and darktable open it, while Safari shows TIFF; Chrome, Edge and Firefox download it instead of displaying it.
How to convert CR2 to TIFF on Windows, Mac, iPhone and Android
On Windows
Open this page in Chrome, Edge or Firefox, drag your CR2 files in from File Explorer, and press Convert. Each TIFF is saved to your Downloads folder.
On a Mac
Safari, Chrome and Firefox all work. Drag the CR2 files from Finder onto the drop zone and the TIFF files land in Downloads. Preview can do single images too: open the file, choose File, then Export, and pick TIFF.
On iPhone and iPad
Open the page in Safari and tap Choose CR2 files. You can pick from Photos or from the Files app. The converted TIFF appears in Files, in the Downloads folder; to put it in your photo library, open it there, tap Share and choose Save Image.
On Android
Open the page in Chrome, tap Choose CR2 files and pick them from Files or your gallery. The TIFF is saved to the Download folder, where any file manager can find it.
Best settings for CR2 to TIFF
There are no settings: camera white balance, sRGB colour and the full sensor resolution, up to 16,384 pixels a side.
For exposure, colour and lens corrections, develop the CR2 in Lightroom, darktable or RawTherapee instead; this converter gives a quick, faithful result without edits.

About CR2 and TIFF files
What is a CR2 file?
CR2 is the raw format of Canon's EOS cameras, from the EOS-1D Mark II in 2004 until Canon moved to CR3 around 2018. It is built on TIFF and holds the unprocessed sensor data together with a full-size JPEG preview.
What is a TIFF file?
TIFF is the format printers and archives trust because it can store uncompressed or losslessly compressed pixels, CMYK colour and several pages in one file. It is also why a single scan can run to 100 MB.
CR2 to TIFF not working? Common problems
- "Files up to 25 MB can be converted." Server conversions have a size limit, and raw files from high-resolution cameras can pass it. Switch the camera to its compressed raw setting, or develop very large files in a desktop raw editor.
- "This file is not really in CR2 format." The converter checks every file before it runs anything, so a file of another format renamed to .cr2 is refused. Choose the page for its real format.
- "The photo could not be read." The decoder on our server, LibRaw 0.20, knows cameras released up to about 2020. Raw files from newer models, and Canon CR3 and Sigma X3F files, may not open.
- The colours look flat. The photo is developed neutrally, without the contrast and styles a camera adds to its own JPGs. Adjust it in a photo editor.
Convert CR2 to TIFF from the command line
LibRaw and ImageMagick do the same on your own computer:
dcraw_emu -w -o 1 -q 3 -T input.cr2
magick input.cr2.tiff output.tiffConverting on your own computer keeps the file entirely local, which is worth it for very large or very sensitive documents. For everything else, the converter on this page does it without installing anything.
CR2 to TIFF converter FAQ
Will I lose quality converting CR2 to TIFF?
The TIFF is 8 bits per channel, while the CR2 held 12 or 14 bits of sensor data, so the extra room for adjusting exposure and colour is gone. Keep the CR2 for editing.
Why is the TIFF a different size from the CR2?
Often larger than the CR2, because a lossless TIFF of a developed full-colour picture holds three values per pixel, where the CR2 held one.
Are my CR2 files uploaded?
Yes, for this conversion. A faithful CR2 to TIFF conversion needs LibRaw and ImageMagick, two open-source tools, which cannot run in a browser. The file travels over an encrypted connection, is converted in a private temporary folder, and is deleted together with the TIFF as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several CR2 files to TIFF at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open a TIFF file?
Safari shows TIFF; Chrome, Edge and Firefox download it instead of displaying it. TIFF is common for print production, scanning, archiving and medical imaging.
Is this CR2 to TIFF converter free?
Yes. There is no sign-up and no watermark. Because this conversion uses our server, there is a fair-use limit of 25 MB per file and a number of files per hour, which stops the service being overloaded.
Can I convert CR2 to TIFF on my phone?
Yes. It works in Safari on iPhone and iPad and in Chrome on Android. The conversion happens on our server, so it is as fast on a phone as on a computer; the TIFF is saved to your Downloads folder.
