About WebP to PDF
WebP to PDF turns pictures in Google’s WebP format into an ordinary PDF that any computer, printer or email client can open. Your browser decodes each WebP, the picture is placed on a page, and the PDF is saved to your device, all inside this tab.
Most WebP files arrive by accident. Websites send WebP to browsers that support it, so "Save image as" on a product photo, a recipe or a news picture often hands you a .webp that other programs refuse to open. A PDF is the easy way to file it, print it, or attach it to a form.
How it works
- Choose the .webp files, or drop them on this page. Pictures in other formats can join them.
- Drag the thumbnails into the order you want the pages in, or use the Move button on one to type its position.
- Set the page size and margin, or choose Fit to image to make each page the size of its picture.
- Convert and download. If the PDF is bigger than you expected, see the section below on shrinking it.
Why the PDF is bigger than the WebP
PDF has no way to store WebP’s compression, so the picture has to be saved again in a form a PDF can hold. This tool saves it losslessly, which adds no new blur but gives up the very small file sizes WebP is known for. The growth can be large:
- A 1600 by 1200 picture saved from a website, 24 KB as WebP, became a 568 KB PDF.
- A 4032 by 3024 picture, 88 KB as WebP, became a 1.5 MB PDF.
Shrinking the result with Compress PDF
Open the finished PDF in Compress PDF and it re-saves the picture as JPEG, which is close to what the WebP was doing in the first place. Measured on the 568 KB PDF above:
- Good (JPEG 80%) at 144 ppi: 66 KB, with the picture kept at about 1587 by 1190 pixels, nearly all of it.
- Best (JPEG 92%) at 300 ppi: 108 KB, at the full 1600 by 1200.
- Medium (JPEG 65%) at 72 ppi: 19 KB, with the picture cut to about 793 by 595 pixels. Fine for a quick attachment, not for printing.
Animated and transparent WebP
An animated WebP, such as a chat sticker or a short looping clip, becomes one still page showing its first frame. We checked this with a two-frame file, red then blue: the PDF page was red. There is no option to lay the frames out as separate pages.
A WebP with a transparent background keeps it. The clear areas show the white page behind them rather than a solid block of colour.
Every current browser can decode WebP. If yours cannot open a particular file, the conversion stops and names it; opening the picture in another browser, or re-saving it as PNG, gets round that.
Frequently asked questions
A PDF cannot keep WebP’s compression, so the picture is stored again without loss. That avoids a second round of blur but costs space: a 24 KB WebP produced a 568 KB PDF. Compress PDF can bring it back down.
On that 568 KB example, Good quality at 144 ppi gave 66 KB while keeping nearly every pixel, and Medium at 72 ppi gave 19 KB by halving the picture’s width and height. Pick Good unless the file has to be tiny.
Many sites serve WebP to any browser that can show it, because it loads faster. "Save image as" keeps whatever the site sent, so a photo that looked like a JPG on the page lands on disk as a .webp file.
Only its first frame is used, as a single page. The rest of the animation is not included, and the tool cannot spread the frames across several pages.
Yes. The see-through parts stay see-through in the PDF, so a cut-out or sticker sits on the white page without a box behind it.
Yes. Add them together and drag them into order. A JPG goes in unchanged, so it will usually take less room in the PDF than a WebP of the same size.
The conversion stops and names the file your browser could not read. Try the same file in a different browser, or open it in an image viewer and save it as PNG, then add that instead.
No. Decoding the WebP, drawing it and writing the PDF all happen in your browser’s memory, and the result goes straight to your downloads.
