Drop your PNG images below and shrink them by up to 90% — losslessly. AVIF keeps every pixel and every transparent background at a fraction of PNG’s size. Bulk conversion, everything happens locally in your browser.
PNG is lossless but notoriously heavy — screenshots, logos and UI graphics often weigh hundreds of kilobytes. Lossless AVIF typically reduces them by 80-90% while keeping every pixel identical, which makes pages load dramatically faster.
Yes. Tick the "Lossless" box and the output is pixel-for-pixel identical to your PNG — just dramatically smaller. Leave it unticked and use the quality slider instead for even smaller files that are visually indistinguishable.
Yes. AVIF supports a full alpha channel just like PNG, so logos, icons and graphics with transparent backgrounds convert cleanly.
All modern browsers (Chrome, Edge, Firefox, Safari 16.4+) open AVIF natively. Some older apps and image editors do not support it yet — for those, keep the original PNG or convert AVIF back to PNG.
Yes. No account is required, no watermarks are added, and images are not shared with third parties. Conversion happens entirely in your browser — files are never uploaded to a server.
