What is AVIF compression?
AVIF compression reduces the file size of a AVIF file while keeping it as visually close to the original as possible. Instead of uploading files to a remote server and waiting for processing, Pixvert's AVIF compressor runs the entire operation locally in your browser using the Canvas API, so AVIF files never leave your device.
AVIF is built on the AV1 video codec and typically produces files 50% smaller than JPG at equivalent visual quality, making it one of the most efficient formats for web delivery today.
AVIF achieves extraordinary compression ratios. Even a lightly compressed AVIF is significantly smaller than JPG or WebP at the same perceived quality — ideal for modern web delivery. Whether you're preparing files for a website, an email, or cloud storage, compressing AVIF images first means faster uploads, less bandwidth used, and quicker load times for anyone who opens them.

Frequently Asked Questions
Is AVIF supported by all browsers?
AVIF is supported by all major modern browsers (Chrome, Firefox, Edge, Safari 16+). For older browser support, keep a WebP or JPG fallback.
Why compress an already-efficient AVIF file?
Camera exports and design tools often use conservative AVIF quality settings — recompressing can still reduce size further for web delivery.
Is it safe to compress my images here?
Yes. Everything happens locally in your browser using the Canvas API — your files are never uploaded to a server.
Is there a file size limit?
There is no hard limit set by Pixvert, but very large files depend on your device’s available memory to process smoothly.
Can I compress multiple files at once?
Yes, drop several files at once and click Compress All — every file is processed and can be downloaded individually or as a ZIP.
Can I use the compressed images commercially?
Yes, Pixvert only reduces file size — it does not alter your rights over the image or add any watermark.
