Turn WebP images into a PDF

or drop them here
Choose at least one JPG or PNG image first.

Choose WebP images, put them in order, and build one checked PDF without an upload. The browser decodes each WebP into lossless pixels and preserves its dimensions and transparency. Match each page to its image or use A4 or US Letter with the margin you choose. The finished page count, page sizes and embedded image dimensions are verified before download.

How to turn WebP images into a PDF

  1. Choose WebP images

    Choose one or more .webp files, or drop them on the page. The browser decodes each image in this tab.

  2. Line up the saved images

    Images saved from web pages often carry long generated names. Use the preview beside each row to put them in order, and remove the ones you saved by mistake.

  3. Choose a page

    Match image keeps each picture's proportions at 96 pixels per inch. A4 or US Letter suits a set you will print or send as a document.

  4. Build, check and download

    The new PDF is reopened and each page image is measured against the decoded WebP. The download appears only when every width and height agrees.

What goes into the PDF

Each WebP is decoded by the browser and written into the PDF as a lossless PNG image. This keeps its decoded width, height and alpha channel. It does not keep the WebP compression stream, so the PDF can be larger than the source files. Animated WebP files contribute their first frame.

Where WebP to PDF fits

pdfpix is a free WebP to PDF converter that needs no account and sets no daily cap. The page is online, but nothing about the convert step is remote: the browser decodes each WebP and the PDF is written in this tab, so the images never reach a server.

WebP is a web delivery format. It is what a site sends to a browser, and it is usually the last thing an email client, a print shop or a document reader will accept. A PDF page is the version other people can open without installing anything. Every WebP the browser can display works here, lossy and lossless alike, and an animated WebP contributes its first frame as one page.

The decoded pixels, the width, the height and the alpha channel all survive. What does not survive is the WebP compression stream itself, because a PDF has no way to store one: the image is rewritten as a lossless PNG instead. Expect a PDF noticeably larger than the WebP files that went into it. That is the trade for a file everything can open, and Compress PDF takes the size back down when it matters.

To place these pages inside an existing document, use Merge PDF. Files already saved as PNG belong in PNG to PDF, camera photos in JPG to PDF, and a mixed folder in Images to PDF.

Questions

Are my WebP files uploaded?
No. Your browser's own WebP decoder reads each file, and the PDF is written in the same tab.
Does WebP to PDF change image quality?
The browser decodes each WebP once and stores those pixels as a lossless PNG image inside the PDF. The pixel width, height and transparency are kept, but the original WebP compression stream is not.
What happens to an animated WebP?
The first frame becomes the PDF page. A PDF page does not animate.
Why can the PDF be larger than the WebP files?
WebP is compact. The PDF stores lossless PNG data so it can preserve the decoded pixels and transparency, which can take more bytes.
Can it read lossy and lossless WebP?
Yes. Any WebP this browser can display is accepted, lossy, lossless or with an alpha channel.
Will a renamed file work?
The tool reads the file's first bytes, not its name. A WebP saved with a .jpg extension is still read as WebP, and a file that is not WebP is refused.
