Free online CR2 to TIFF converter

A publishing, printing, scanning, or editing application may require TIFF even though a Canon camera produced the image as CR2. Converting creates a widely supported, high-bit-depth image for editing, archiving, or delivery, but the TIFF is usually much larger than a JPEG.

What the CR2 format is

CR2 (Canon Raw Version 2) is Canon's raw photograph format, used by many EOS DSLR cameras and some early mirrorless models. It stores mostly unprocessed sensor data rather than a finished RGB image, together with exposure metadata, a preview, and camera-specific information. CR2 files are created when the camera is set to RAW or RAW+JPEG.

A raw processor such as Adobe Lightroom, Adobe Camera Raw, Canon Digital Photo Professional, darktable, or RawTherapee interprets the sensor data. Its settings determine white balance, demosaicing, exposure, highlight recovery, noise reduction, color rendering, cropping, and output dimensions before a standard image file is produced.

What the TIFF format is

TIFF (Tagged Image File Format) is a tagged raster-image format supported by professional photo editors, desktop-publishing software, scanners, print workflows, and many archival systems. It can store 8-bit or 16-bit-per-channel RGB data, embedded ICC color profiles, resolution metadata, and, in some applications, layers or transparency.

TIFF supports lossless LZW and ZIP compression, as well as uncompressed output. It is suitable when image quality and editing latitude matter more than file size. TIFF is not a raw format: conversion renders the camera data into pixels, so later editing cannot recover information discarded by the selected exposure, white balance, color space, crop, or output resolution.

How to convert CR2 to TIFF

Using Adobe Lightroom Classic

1. Import the CR2 files and adjust exposure, white balance, lens corrections, noise reduction, and cropping as required.
2. Select the photographs and choose File → Export.
3. Under File Settings, set Image Format to TIFF. Select 16 bits/component for further tonal or color editing; use 8-bit output only when the destination requires it or the image is final.
4. Choose the color space required by the workflow. ProPhoto RGB retains a wide editing gamut, while sRGB is safer for general-purpose applications and unmanaged displays.
5. Choose LZW or ZIP compression, select the destination folder, and click Export. Both compression methods are lossless.

Using Canon digital photo professional

1. Open the CR2 files in Canon Digital Photo Professional and apply the required raw adjustments.
2. Select the images and choose File → Convert and save.
3. Set the output type to TIFF, select 16-bit output if available, choose the destination folder, and start the conversion.

Using darktable or RawTherapee

1. Import the CR2 files and make adjustments in the raw-processing workspace.
2. Open the export or batch-processing controls and select TIFF as the output format.
3. Set 16-bit output when additional editing is planned, choose the required ICC profile, enable lossless compression if available, and export the files.

These desktop applications are preferable when you need control over raw rendering, color management, output dimensions, metadata, or batch settings. Adobe Photoshop can also open CR2 files through Adobe Camera Raw and save the rendered image as TIFF, but it is less convenient than a dedicated raw processor for batch conversion.

Using 101convert.com

You can convert CR2 files to TIFF for free on 101convert.com without installing software: open the CR2-to-TIFF converter, add the file, start the conversion, and download the resulting TIFF. A desktop processor is preferable for irreplaceable photographs, confidential files, or workflows that require precise control over raw adjustments and color profiles.

Quality and compatibility considerations

• Keep the original CR2 files. A TIFF contains the rendered result, not the complete raw sensor data or the full set of nondestructive adjustment options.
• Use 16-bit TIFF when the image will receive substantial tonal or color editing. It reduces rounding and posterization compared with 8-bit output, but increases file size and may not be supported by every application.
• Embed an ICC profile so other software can interpret the colors correctly. Adobe RGB is common in some print workflows; sRGB generally provides broader compatibility.
• Check the exported pixel dimensions. An export preset can resample the image even when the original CR2 contains the camera's full resolution.
• LZW and ZIP reduce storage size without changing pixel data, but a compressed TIFF can still be much larger than a JPEG. Avoid JPEG TIFF compression when maximum lossless quality is required.
• TIFF support varies for layers, alpha channels, tiled images, BigTIFF, and uncommon compression types. For broad compatibility, use a standard RGB TIFF with 8- or 16-bit channels and LZW or ZIP compression.
