Convert WebP to PDF
Images downloaded from the web are increasingly in WebP format, which some applications still struggle to open. This tool decodes each WebP through your browser’s native decoder, then inserts it into a PDF — one page per image, sized on the real bitmap dimensions, the same way “image to PDF” already does for PNG and JPEG. Up to 20 files and 50 MiB total. Typical uses: attaching WebP captures to an administrative file, archiving visuals in a universal format, sending images to someone whose viewer does not read WebP. Everything runs on your device. The PDF is a static document rather than a collection of WebP files for the recipient to decode. Internally, the browser decodes the image to a bitmap, exports that bitmap as PNG and embeds the PNG into the PDF. There is no OCR step: words inside a screenshot remain pixels, not searchable document text. Page dimensions follow bitmap width and height in PDF points, so a large screenshot does not automatically become an A4 sheet. Images with different proportions produce differently shaped pages. Review those dimensions before printing, particularly for tall web captures. Transparent pixels are carried through the PNG intermediate rather than deliberately flattened onto a chosen background. No background-colour control is offered. Keep the WebP originals if you later need to edit or republish the web assets; the PDF is the assembled reading copy, not a source-image archive. Each input contributes exactly one page; this workflow does not arrange several screenshots into a contact sheet or add a title page between them.
FAQ
Does the PDF keep my image order?
Pages follow the order of your images — drop them in sequence or name them alphabetically for a correctly ordered document.
Why PDF rather than keeping the WebP files?
PDF opens everywhere, prints predictably and archives as one document — the format portals and recipients reliably accept.
Do the source images change?
No — the WebP files are only decoded for assembly; the originals on your device stay untouched.
Can I assemble more than 20 images?
Convert batches of at most 20 images, then merge the resulting PDFs within the file, byte and page limits shown by Merge PDF. A larger allowance does not remove the image adapter’s 20-image cap.
Will the images look identical in the PDF?
Decoded then re-encoded losslessly for embedding — what you see in the browser is what lands on the page.
How many images per PDF?
Up to 20 WebP files, 50 MiB total — one page per image, in drop order.
Is the quality preserved?
The WebP is decoded then losslessly re-encoded for PDF insertion — no second lossy compression.
What about animated WebP?
Only the first frame of an animated WebP is decoded — the target format is a static document.
Are my images sent anywhere?
No — decoding and PDF assembly happen entirely in your browser.
Can I mix WebP, PNG and JPEG?
Use Image to PDF for a mixed-format selection. The dedicated WebP picker advertises WebP files, while the shared image converter supports PNG, JPEG, WebP and AVIF.
What page size?
Each page takes the dimensions of the source image, as in “image to PDF”.
Does the PDF keep the WebP compression?
Images are embedded at their original quality — the converter repackages the pixels without recompressing. Files stay light, and multiple images can be combined into one document with one page each.
How to proceed
