PNG screenshots and logos to WebP: smaller pages, same picture, nothing uploaded
Processed in your browser. Nothing is uploaded. Updated on 24 Oct 2026.Two formats, two different jobs: PNG and WebP. PNG is lossless and keeps transparency, which is why logos, screenshots and interface graphics use it. WebP, by contrast, gives you roughly a quarter off the file size at the same visible quality, transparency included. WebP is lossy, so a little detail is thrown away. Add a file, check the choice we have already made for you, and press the button once.
Choose the PNG images; WebP is already set and keeps the transparent background.
Move the Quality slider to trade size for detail, since WebP is saved lossy here.
Press Convert to WebP; the totals above the box then show the size before and after.
Press Download to save them, several at once as a zip.
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.
Two jobs are refused on purpose. GIF is not written, because a good GIF needs a hand-chosen 256-colour palette and a bad one looks worse than the original. Camera RAW and Photoshop PSD files are not opened, because both need decoders far too large for a browser; export a JPEG or TIFF from your camera software, or a PNG from Photoshop, and bring that here. Nothing becomes an SVG: tracing pixels into shapes is a different job with different results.
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.
Twenty files per batch and 50 MB per file. Nothing is uploaded: the conversion runs in your browser, the TIFF and HEIC readers load only when one of those files arrives, and the converted files are built on your own device.
