About formats

CRW is Canon's first-generation RAW image format, based on the Camera Image File Format (CIFF) specification developed jointly by Canon, Kodak, and other imaging companies in the late 1990s. Used by Canon's consumer and prosumer cameras from approximately 1998 through the early 2000s — including the PowerShot G-series, EOS D30, EOS D60, and EOS 10D — CRW files store the unprocessed 12-bit sensor readout in a heap-based container structure that differs fundamentally from the TIFF-derived approach used by most other camera manufacturers. The CIFF container organizes data into a hierarchical directory of heap entries, each identified by type and tag, containing the raw image data, JPEG thumbnail, EXIF information, and Canon's proprietary metadata including White Balance tables and Picture Style parameters. CRW was eventually replaced by the CR2 format starting with the EOS-1D Mark II in 2004, as Canon moved to a TIFF-based container that aligned more closely with industry conventions and supported higher bit depths. One advantage of CRW files is historical completeness: they preserve the full original sensor data from an important transitional period in digital photography, and the 12-bit captures from cameras like the EOS D30 still produce excellent results when reprocessed with modern RAW converters. Broad legacy support is another strength — despite its age, CRW remains readable by Adobe Lightroom, Photoshop, RawTherapee, and other modern converters, ensuring these early digital negatives remain accessible.
Developer: Canon
Initial release: 1998
AVIF (AV1 Image File Format) is a modern image format derived from the AV1 video codec, developed by the Alliance for Open Media and specified in February 2019. The format leverages the intra-frame coding tools of AV1 — a royalty-free video codec backed by Google, Apple, Microsoft, Amazon, Netflix, and other major technology companies — to compress still images with substantially higher efficiency than JPEG, PNG, or even WebP. AVIF stores images in the HEIF (High Efficiency Image File Format) container, supporting both lossy and lossless compression, HDR (high dynamic range) with wide color gamuts up to 12-bit depth, alpha transparency, and animated sequences. At equivalent visual quality, AVIF files are typically 30-50% smaller than WebP and 50-70% smaller than JPEG, representing the largest compression improvement in mainstream image formats in over a decade. One advantage is exceptional compression efficiency — AVIF delivers visually indistinguishable images at dramatically lower file sizes, directly reducing bandwidth consumption and improving page load times for web content. The royalty-free licensing model provides another key strength: unlike HEIC/HEIF which relies on patent-encumbered HEVC, AVIF's AV1 foundation is free for anyone to implement without licensing fees. Browser support has reached broad adoption, with Chrome, Firefox, Safari, and Edge all rendering AVIF natively. The format is rapidly gaining adoption for web images where quality-to-size ratio is paramount.

Frequently Asked Questions

What are the reasons to convert CRW to AVIF?

CRW captures Canon's original RAW data in an aging format — transformation to AVIF migrates your classic digital photos into a modern, widely supported standard.

How do I open an AVIF file?

AVIF works with Chrome, Firefox, Safari, Edge, GIMP, and Photoshop 2024+.

Is my CRW file safe during conversion?

Yes — uploaded CRW files are deleted immediately after conversion, and the AVIF output is removed from servers within 24 hours for your privacy.

Does the converter work on all devices?

Convertio works on any device with a web browser — desktop computers, laptops, tablets, and phones across all operating systems.

Does converting CRW to AVIF affect quality?

Your CRW image data is processed carefully during conversion. The resulting AVIF retains the maximum quality the target format can support.
