About the JPG to AVIF Converter
This tool converts JPG and JPEG photos into AVIF, the AV1-based image format that delivers roughly 50% smaller files than JPEG at the same visual quality. Choose a quality level, convert, compare the before/after size, and download the .avif file.
AVIF is now viewable in all major browsers, making it a top choice for performance-focused websites chasing perfect PageSpeed scores. Smaller images mean faster Largest Contentful Paint and better SEO.
Encoding uses your browser's built-in AVIF encoder, so files never leave your device. Note that AVIF encoding (as opposed to viewing) requires a recent Chromium browser — the tool tells you clearly if yours can't encode it.
Frequently asked questions
Is AVIF better than JPEG?
For compression, dramatically — AVIF files are commonly half the size of a JPEG that looks the same. It also supports transparency, HDR and wide color gamuts. JPEG only wins on universal support in very old software.
Which browsers can create AVIF files?
Encoding AVIF in the browser currently works in recent Chrome, Edge and other Chromium-based browsers. Firefox and Safari can display AVIF but generally can't encode it via canvas — if conversion fails here, switch to Chrome or Edge.
What quality setting should I use for AVIF?
AVIF stays sharp at surprisingly low settings: 50–65 is excellent for web photos, and 70–80 is essentially indistinguishable from the original. Start at 60 and only raise it if you notice smoothing in fine textures.
Should I use AVIF or WebP for my website?
AVIF compresses better (often 20–30% smaller than WebP), while WebP encodes faster and has slightly wider legacy support. The ideal setup serves AVIF with a WebP fallback via the HTML picture element.
Does converting JPG to AVIF lose quality?
Both formats are lossy, so re-encoding discards a little data — but AVIF is so efficient that at moderate settings the difference is invisible while the file shrinks by half. Keep your original JPG as the master copy.
