Convert to AVIF for the smallest images on the web
AVIF is the most efficient widely-supported image format for photographs — frequently half the size of a JPEG at the same quality. Optimagio encodes AVIF with avifenc and libavif, with an automatic libvips fallback, so you get tiny files without a fragile toolchain.
- Often ~50% smaller than JPEG at comparable quality
- Encoded with avifenc/libavif, fallback to libvips
- Serve AVIF with a WebP fallback for full coverage
Real product capability — not a placeholder.
What is AVIF?
AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec. It delivers excellent compression for photographic content, supports wide color gamut and high dynamic range, and handles transparency — making it the smallest practical format for most photos today.
AVIF trade-offs to know
AVIF encoding is more CPU-intensive than JPEG or WebP, so conversion takes a little longer. Browser support is now broad across current Chrome, Firefox, Safari, and Edge, but a common pattern is to serve AVIF first with a WebP fallback for the long tail. Optimagio can produce both formats so you can ship a complete <picture> strategy.
AVIF without the headaches
Robust encoding
avifenc/libavif handles the heavy lifting, with an automatic libvips fallback if a source needs it.
Photo-grade results
Wide-gamut and HDR-adjacent color survive the conversion for portfolios and product photography.
Pair with WebP
Generate AVIF and WebP variants so you can ship AVIF-first with a safe fallback.
Batch and API
Convert thousands of images in one job, or call the API with format=avif.
Resize together
Downscale to display size in the same pass to compound the savings.
Safe defaults
EXIF stripped by default, orientation baked in, decompression-bomb guard always on.
Need AVIF across a whole catalog?
Pro handles 50,000 images a month and Business 100,000 — both at file sizes large enough for high-resolution photography (100 MB and 150 MB per file). Scale goes beyond 500,000 with custom limits.
Frequently asked questions
Is AVIF smaller than WebP?
For photographic content AVIF is usually smaller than WebP at the same quality, sometimes significantly. For simple graphics and very small images the difference narrows, and WebP encodes faster.
Do browsers support AVIF?
Current versions of Chrome, Firefox, Safari, and Edge support AVIF. Because some older clients do not, many sites serve AVIF with a WebP or JPEG fallback — Optimagio can generate every variant you need.
How do I convert images to AVIF with Optimagio?
Upload an image and choose AVIF as the output, or send format=avif to the optimize API. For large jobs, run a batch and download the converted files as a ZIP.
