Frequently Asked Questions
What makes AVIF superior to WebP and JPEG?
AVIF (AV1 Image File Format) is an open-source format developed by the Alliance for Open Media (AOMedia). It leverages the modern AV1 video codec to achieve up to 50% smaller file sizes than WebP and up to 80% smaller sizes than traditional JPEG, with support for 10-bit and 12-bit color depth, transparency, and HDR.
Which browsers support the AVIF image format?
AVIF decoding is natively supported in Google Chrome, Mozilla Firefox, Apple Safari (iOS 16+ & macOS Ventura+), Microsoft Edge, and Opera. For browser-side encoding via Canvas, modern Chromium browsers (Chrome 116+, Edge) offer full acceleration.
Can I convert multiple images to AVIF at the same time?
Yes. SizeSnap allows you to upload multiple JPG, PNG, or WebP photos, choose your target quality, convert all files in batch, and download them individually or as a single ZIP archive.
Are my photos uploaded to a cloud server?
No. All processing occurs locally within your browser sandbox. Your images are never transmitted or stored on remote servers.
