WebP to PDF
One or many WebP images into a single document, one image per page, in the order you choose them. JPG and PNG work here too.

Why WebP needs converting at all
WebP is a web format. Browsers read it, and that is mostly where its support ends: print shops, document management systems, court filing portals, university submission systems and most desktop software either refuse it or render it wrong. PDF is the format all of those accept, so converting is usually about getting an image somewhere it will actually be opened — not about the image itself.
That also explains where WebP files usually come from. Saving an image
from a website in 2026 frequently gives you a .webp rather
than a JPG, which is why people hit this problem without ever choosing
the format.
Lossy or lossless — and why it matters here
WebP is two formats wearing one extension. Lossy WebP works like JPEG: detail was discarded when the file was made. Lossless WebP works like PNG: every pixel is preserved. Nothing in the filename tells you which you have.
It matters because a PDF cannot store WebP at all — the format has no WebP image type. The image is decoded and re-encoded on the way in, and what that costs depends on which kind you started with:
- Lossy WebP — the picture has already been through one lossy pass. Re-encoding costs a little more detail, usually invisible at reading size and visible if you zoom into text or a hard edge.
- Lossless WebP — nothing was lost yet, so the file is typically larger and the conversion has more to preserve. Screenshots and graphics are usually this kind.
If you also have the original JPG or PNG, convert that instead: Images to PDF carries JPG and PNG data into the document without re-encoding it at all, which WebP cannot avoid.
Two things to check in the result
Transparency. WebP supports an alpha channel, and many images saved from websites use it — logos and cut-out product shots in particular. Open the finished PDF and confirm anything that relied on a transparent background sits on the page the way you expected.
Animation. WebP can hold an animation, like a GIF. A PDF page has no time dimension, so an animated WebP becomes a single still. Check it is the frame you wanted.
Getting the page order right
Images are read in the order you choose them, and most file pickers hand
them over in name order. Renaming to 01-…, 02-…
before you start is faster than reordering afterwards — and note that
10 sorts before 2 unless the numbers are padded.
If the result is larger than you need — a batch of full-resolution images easily exceeds an email limit — send it to Compress PDF rather than shrinking the images first. That keeps your originals untouched and lets you see the real byte count before deciding what to trade away.
