Convert Any Image to AVIF — Maximum Compression, Alpha Intact

AVIF is the most efficient widely-supported image format available today. Built on the AV1 video codec, it consistently delivers smaller files than WebP and JPG at the same visible quality level — often dramatically so for photographs and graphics alike. Enhydra RPO processes a mixed batch of source formats in one run: RAW camera files, scanned TIFFs, PNGs with transparency, legacy BMPs, all converted to AVIF without re-uploading between tools.

One important limitation to know before you start: AVIF does not support animation. If your source is an animated GIF or animated WebP, only the first frame is encoded — the motion is not carried over. For transparency, AVIF handles alpha channels natively, so PNG and WebP sources with transparent areas convert without any background fill. EXIF metadata is stripped by default; a keep option is available if you need to preserve shooting data.

Why AVIF Compresses Better Than WebP and JPG

AVIF encodes images using the same perceptual model as the AV1 video codec — a technology developed by a broad industry alliance specifically to push compression efficiency forward. The practical result:

Photographs: AVIF lossy typically produces files 40–55% smaller than equivalent-quality JPGs, and noticeably smaller than WebP lossy at the same visual fidelity.
Graphics and illustrations: AVIF lossless competes with PNG and WebP lossless, often winning on file size for smooth gradients and photographic content embedded in design files.
HDR and wide color: AVIF natively supports 10-bit and 12-bit color depth, making it the only mainstream web format that can carry HDR captures from modern cameras without downsampling.

The trade-off is encode time: AVIF encoding is CPU-intensive and slower than WebP or JPG. For a batch of 200 files, expect the job to take longer than equivalent WebP batches.

Transparency, Color Accuracy, and RAW Development

Alpha transparency is a first-class feature of AVIF. Sources with an alpha channel — PNG, WebP with alpha, AVIF with alpha — produce AVIF output with the transparency intact. No white or black fill is applied; the transparent areas remain transparent.

For sources without an alpha channel (JPG, TIFF, BMP, most HEIC files), the output is opaque AVIF with no change to the visible image.

RAW camera formats (CR2, CR3, NEF, ARW, DNG, RAF, ORF, RW2) are developed using standard parameters before encoding. The RAW processor applies white balance and exposure compensation; the result is comparable to what a default camera JPEG would look like, then compressed to AVIF.

Browser and Platform Support

AVIF is supported in all current versions of Chrome, Edge, Firefox, and Safari (macOS 13 / iOS 16 and later). If your audience includes users on older iOS or older Safari, you may want to serve AVIF with a WebP or JPG fallback using an HTML <picture> element.

For workflows that do not involve web delivery — archiving, print prepress, digital asset management — AVIF is less universally accepted than TIFF or JPG. Check that your downstream software can open AVIF before committing a full archive conversion.

FAQ

Will my animated GIF be converted to animated AVIF?

No. AVIF does not support animation. Only the first frame of an animated source is encoded. If you need an animated output format, convert to WebP or keep the source as GIF instead.

Is alpha transparency preserved when converting PNG to AVIF?

Yes. AVIF supports alpha channels natively. Transparent areas in a PNG or WebP source remain transparent in the AVIF output — no background color is applied.

Why does AVIF conversion take longer than WebP?

AVIF encoding is computationally heavier than WebP or JPG encoding because it uses the AV1 compression algorithm. Larger batches and higher-resolution images will take noticeably more time to process.

Can I convert RAW files (CR2, NEF, ARW, DNG…) directly to AVIF?

Yes. RAW formats are developed first — white balance and exposure applied — then encoded to AVIF. No separate RAW converter is needed.

What happens to EXIF data during conversion?

EXIF metadata is stripped by default to minimize file size and protect privacy. If you need to keep shooting data — camera model, GPS, timestamps — enable the keep-EXIF option before starting the batch.
