    How it works

    Converting WebP, AVIF, BMP to PDF

    1

    Drop your files in

    WebP, AVIF, BMP and GIF. Your browser's own decoder reads them, which is why this page loads nothing extra.

    2

    Re-encoded once, at high quality

    PDF has no filter for any of these formats, so each is written again — JPEG at 92% for photographs, PNG where there is transparency.

    3

    Download the PDF

    Which every reader on every platform will open, unlike the file you started with.

    Why these formats need converting at all

    WebP is what most websites now serve, so it is what you get when you save an image from one. AVIF is its newer, smaller successor. Both are excellent on the web and unwelcome almost everywhere else: Word, PowerPoint, older photo software and most print workflows will not take either. BMP has the opposite problem — ancient, universally readable, and enormous, because it stores every pixel uncompressed.

    A PDF is the common denominator that all of them can become.

    These cannot be embedded untouched

    PDF defines image filters for JPEG and a handful of others. It has none for WebP, AVIF, BMP or GIF, so there is no version of this conversion that copies the file in unchanged — by anyone's tool, not just ours. Each image is decoded by your browser and written once: JPEG at 92% quality for photographs, PNG when the image has transparency or is graphics rather than a photo. Force PNG for everything with Image quality → Lossless if the size does not bother you.

    Animated GIF and animated WebP

    A PDF page does not move, so only the first frame is used. That is stated before you convert rather than as a surprise afterwards. If you need every frame, you need a different kind of tool.

    When a browser cannot decode the file

    AVIF needs Chrome 85+, Firefox 93+ or Safari 16+; WebP needs Chrome 32+, Firefox 65+ or Safari 14+. On something older, the tool names the versions that work rather than failing with a shrug. Since decoding happens on your device, the browser is the only thing that decides.

    BMP, and why your PDF may shrink dramatically

    A BMP stores raw pixels with no compression at all, so a 20 MB BMP is routine for an image a JPEG would hold in 800 KB. Converting to PDF compresses it for the first time, and the result is often a fraction of the original. That is not data being lost — it is compression finally being applied.

    FAQ

    WebP, AVIF, BMP questions

    Why can't I just put a WebP into a PDF as-is?
    The PDF format defines no image filter for WebP, so every converter must decode and re-encode it. Any tool claiming otherwise is describing something the format does not allow.
    Does converting WebP to PDF lose quality?
    One re-encode, at 92% JPEG quality by default, which is visually indistinguishable at normal viewing sizes. Choose Lossless under More options if you would rather have a much larger, pixel-exact file.
    Will my animated GIF still animate?
    No. PDF pages are static, so the first frame is used. The tool says so before you convert.
    Do I need to install anything for AVIF?
    No. Your browser decodes it, provided it is Chrome 85+, Firefox 93+ or Safari 16+.
