AVIF vs RAW
A detailed comparison of AVIF Image and Generic RAW Image — file size, quality, compatibility, and which format to choose for your workflow.
AVIF Image
Raster & Vector ImagesAVIF is a next-generation image format based on the AV1 video codec. It offers significantly better compression than JPEG and WebP while maintaining excellent visual quality, including HDR and wide color gamut support.
About AVIF filesGeneric RAW Image
Raster & Vector ImagesRAW is a generic term for files containing minimally processed data from a camera image sensor. Various camera manufacturers use proprietary RAW variants, but the term broadly refers to any unprocessed sensor capture that retains maximum editing flexibility.
About RAW filesStrengths Comparison
AVIF Strengths
- Best-in-class compression efficiency — 30-50% smaller than JPEG for the same quality.
- Royalty-free and patent-unencumbered (unlike HEIC).
- Supports alpha transparency, HDR, wide gamut (BT.2020), and up to 12-bit color.
- Progressive decoding: a blurry preview appears while the file is still downloading.
- Supported in all major browsers since late 2022 — no polyfills needed.
RAW Strengths
- Every bit of sensor data preserved for post-processing latitude.
- Higher bit depth (12-16 bits) than JPEG (8-bit) — smoother gradients.
- Non-destructive editing in raw processors.
- Rich metadata (EXIF, makernotes, camera settings).
Limitations
AVIF Limitations
- Encoding is CPU-expensive — an AVIF export can take 10-30× longer than JPEG.
- Older software (pre-2022) cannot open AVIF without plugins.
- Email clients still largely ignore it — stick to JPEG for attachments.
- Metadata support (EXIF, XMP) exists but tooling is less mature than for JPEG.
RAW Limitations
- Proprietary per brand — Canon CR2 will not open in a pure-Canon-free processor.
- Huge files compared to JPEG.
- Requires dedicated software (Lightroom, Capture One, Darktable, etc.).
- No universal standard — DNG aims to solve this but adoption is partial.

Frequently Asked Questions
AVIF (AV1 Image File Format) is a cutting-edge image format derived from the AV1 video codec, backed by the Alliance for Open Media. It delivers up to 50% smaller files than JPEG with equal or better visual quality, plus HDR and transparency support.
RAW (Generic RAW Image) is an image format used to store raster graphics — a two-dimensional grid of pixels describing a picture. It is part of the raster & vector images family and designed around a specific trade-off between file size, visual fidelity, and feature support (transparency, colour depth, compression type). Photographers, web designers, and content creators choose RAW when its particular strengths match the publishing target.
AVIF files open in Chrome, Firefox, Safari (from macOS Ventura), Edge, and GIMP 2.10+. Support is growing rapidly, but some older image editors may not yet handle AVIF natively.
Most desktop photo viewers (Windows Photos, macOS Preview, GIMP, Photoshop, Affinity Photo) open RAW natively. On mobile, iOS Photos and Google Photos display RAW in the gallery when supported by the OS. If the format is rare or new, convert to JPG or PNG first — both are universally readable — using our RAW to JPG or RAW to PNG converter.
AVIF provides better compression and quality than WebP, especially for photographs. However, WebP has broader software support today. Use AVIF for maximum performance on modern browsers and WebP as a reliable fallback.
Upload the RAW to KaijuConverter and pick a target format (JPG, PNG, WebP, HEIC, TIFF, BMP, SVG, PDF). The conversion runs in the browser via ImageMagick and returns a download in seconds. No account or installation required; both input and output delete automatically within two hours.
