About WebP to PDF

PDF has no native WebP support — no embedder can copy WebP bytes into a document the way JPG bytes can be copied — so this tool decodes each WebP in your browser with the Canvas API and re-encodes it before pdf-lib writes the file. The policy is spelled out rather than silent: images with any transparency are saved into the PDF as lossless PNG so the transparency survives, and fully opaque images are saved as JPEG at quality 0.92, which keeps a photo-heavy PDF from ballooning. An animated WebP contributes its first frame only, and the tool tells you so on screen the moment the file is added — the loss is never silent. Reorder the pages by dragging, then choose A4, US Letter (image centered inside a 40-point margin, never upscaled), or fit-to-image, where each page matches its image exactly. Because WebP compresses harder than JPEG or PNG, the PDF will usually come out somewhat larger than the source files — the price of putting the pixels in a format PDF viewers understand.

Questions

How does a WebP end up inside a PDF?

PDF has no WebP embedder, so the image is decoded in your browser with the Canvas API and re-encoded first: as lossless PNG if it carries any transparency, or as JPEG at quality 0.92 if it is fully opaque.

What happens to animated WebP files?

Only the first frame becomes a PDF page, and the tool says so on screen the moment you add the file — before you convert — so the loss is never silent.

Does WebP transparency survive?

Yes. Transparent WebPs take the PNG path, and the alpha channel rides into the PDF as a soft mask that viewers composite over the white page.

Why is the PDF larger than my WebP files?

WebP compresses harder than JPEG or PNG, and PDF viewers cannot read WebP data — so the re-encode usually costs some bytes. That is the trade for a file every PDF reader can open.

Is my file uploaded to a server?

No. Transmute processes everything locally in your browser using JavaScript and WebAssembly. Your files never leave your device — there is no server, no upload, no cloud processing.
