    Working…

    Done

    Your files are processed on this device and never sent to a server. Reload the page to clear everything from memory.

    GIF is limited to 256 colours and a single on-or-off level of transparency, which is why old logos, icons and diagrams are often still GIFs. PNG does everything a still GIF does, with better compression, full colour and smooth transparency, and every editor and upload form takes it. The conversion is lossless: the PNG holds exactly the pixels of the GIF.

    Your browser decodes the GIF inside this tab and writes the PNG. Transparent areas stay transparent. An animated GIF becomes a PNG of its first frame; this page does not split animations into separate frames, so use it for still images or when the first frame is the one you want.

    How it works

    1. Drop your GIF files onto the page, or tap to pick them. Batches are fine.
    2. There are no quality settings: PNG is lossless, so the output matches the decoded image exactly.
    3. Download each PNG, or all of them as one zip.

    In your browser, not on a server

    Stayput first reads the opening bytes of each file, where every image format writes its signature, so it knows what the file really is whatever it is called. Your browser decodes JPG, PNG, WebP, GIF, BMP, AVIF and SVG itself; HEIC goes through the libheif WebAssembly decoder, and JPEG XL (or AVIF, in a browser without native support) through the Squoosh decoders, all served from this site and cached. The browser re-encodes JPG, PNG and WebP; PDF, ICO, GIF, BMP and TIFF files are written by small encoders in the page. Nothing here needs a server.

    Compared with upload-based tools: Online converters upload your image, convert it on their machine, keep it for hours and cap you at a few files a day. This does the same conversion on your device, for as many files as you like, in less time than the upload.

    Verify it yourself. Load this page, turn off Wi-Fi or switch to airplane mode, and run the tool. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.

    Questions

    What happens to an animated GIF?

    You get a PNG of the first frame only. Splitting an animation into one PNG per frame is not something this tool does yet.

    Is the transparency kept?

    Yes. A transparent GIF becomes a PNG with the same transparent areas.

    Will the PNG be smaller than the GIF?

    Often slightly smaller for flat graphics, sometimes a little larger. PNG compression is usually better than GIF’s, but the browser does not reduce the palette the way an optimiser would.

    Are my files uploaded?

    No. Everything happens in your browser tab; the GIF never leaves your device.
