CRW
CRW is the camera RAW format of early Canon digital cameras, used before CR2. It stores unprocessed sensor data from the camera. Modern software support for CRW is limited, so converting it to JPG, PNG, or TIFF keeps old photos accessible.

AVIF
AVIF is a modern image format based on the AV1 video codec. It offers much better compression than JPG at similar quality and supports transparency, high dynamic range, and wide color. Current browsers support AVIF, but some older apps and editors cannot open it yet.
What happens when CRW becomes AVIF
Source format
CRW is the image source or target format for this conversion path.
Target format
AVIF can use lossy or lossless compression and supports transparency and high bit depth.
What changes
The CRW pixels are decoded and written using AVIF compression and color capabilities.
- What is preserved
- Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
- What may be lost
- Layers, editable vectors, camera-raw controls, animation, high bit depth, and metadata are preserved only when AVIF supports them.
- Codec and quality implications
- Color profile handling, bit depth, chroma sampling, and compression settings can change appearance or file size.
- Realistic limitations
- Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.
Conversion steps
- Upload a CRW file no larger than 1 GB.
- Confirm that AVIF is selected as the target.
- Download the AVIF file and check the result before deleting your source.
Troubleshooting
- The CRW file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The AVIF file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
- Transparency, color, or animation changed.
- Choose a target that supports the needed feature and keep the original file; JPG cannot store transparency or animation.
Privacy and file retention
Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
