Convert PNG screenshots and logos to AVIF: the smallest modern web format
Processed in your browser. Nothing is uploaded. Updated on 24 Oct 2026.There is a trade in PNG to AVIF, and it is a simple one. What you are after is the smallest file of anything here at the same quality, and you want it because PNG stores every pixel exactly, which is generous for a logo and wasteful for a photograph. AVIF is lossy, so a little detail is thrown away. The whole conversion happens inside this browser tab, so the picture never leaves your device.
Choose the PNG images; AVIF is already set under Convert to and keeps transparency.
If AVIF is greyed out, this browser cannot write it: use Chrome or Edge, as Firefox and Safari usually cannot.
Set Quality; AVIF is lossy and gives the smallest files of any format offered here.
Press Convert to AVIF, then Download the .avif files.
Convert Image reads ten formats and writes seven. It opens JPEG, PNG, GIF, WebP, AVIF, BMP, TIFF, ICO, SVG and HEIC, and saves as JPEG, PNG, WebP, AVIF, BMP, TIFF or ICO. Drop up to twenty files in and each row shows the new size beside the old one as it finishes.
What a conversion costs is stated before it runs, not after the download. JPEG has no transparency, so transparent areas are filled with a colour you pick, white by default. BMP is the same. A multi-page TIFF gives you one file per page by default; an animated GIF or WebP keeps its first frame by default, with every frame available on browsers that can read them. An ICO is written as a genuine icon file holding 16, 32, 48, 64, 128 and 256 pixel versions, each stored as a PNG.
Everything runs on your device. TIFF uses a reader loaded only when a TIFF arrives; HEIC uses a decoder loaded only when a HEIC arrives; an SVG is stripped of anything that could run or fetch and then drawn in an isolated image, at a size you choose. Writing WebP and AVIF depends on the browser, and the tool disables a format it cannot write rather than quietly saving something else. Limits are 20 files per batch and 50 MB per file.
The rest of the article, and all 8 questions about Convert Image, are on the Convert Image page.
Reading works for JPEG, PNG, GIF, WebP, AVIF, BMP, TIFF, ICO, SVG and HEIC; writing works for JPEG, PNG, WebP, AVIF, BMP, TIFF and ICO. That is every pair those two lists allow, about sixty of them, and each pair has its own page with the target format already chosen for you.
Writing AVIF and WebP is done by the browser, and not every browser can. Chrome and Edge write both; Firefox and Safari often cannot write AVIF. A format this browser cannot write is disabled with a note naming the browsers that can, so nothing is silently saved in the wrong format.
Not here, and the page says so up front. Tracing pixels into shapes is a different job, done by Image to SVG on this site, and PSD files are now opened by PSD to PNG, which saves the picture and each layer. Camera RAW differs by manufacturer and needs a decoder too large for a browser; export a JPEG or TIFF first.
Yes. Scripts, event handlers, embedded HTML, external references and entity declarations are stripped out first, and the drawing is then rendered inside an isolated image, where browsers do not run scripts and the file cannot reach the network. It is never inserted into this page. You choose the pixel size it is drawn at.
