Turn WebP images into a PDF

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

WebP to PDF turns one or more WebP images into a single checked PDF without uploading them. The browser decodes each WebP into lossless pixels and preserves its dimensions and transparency. Choose A4 or US Letter, or match each page to its own image, and the finished PDF is reopened and verified before download.

How to convert WebP to PDF in your browser

  1. Choose WebP images

    Pick one or more .webp files, or drag them onto the page. The browser decodes each image in this tab, so nothing leaves your device.

  2. Put them in order

    Use the arrow buttons to set the page order. Each WebP image becomes one PDF page, and the order you see is the order you get in the file.

  3. Choose the page fit

    Match each page to its image for graphics of varying shapes, or use A4 or US Letter for a document that prints on standard paper. Add no margin, a narrow margin, or a standard margin.

  4. Read the receipt, then download

    The completed PDF is opened again inside the browser. Its page count, page sizes, and embedded image dimensions must all match before the download button appears.

How does WebP to PDF preserve pixels and transparency?

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 only.

WebP is a web delivery format: compact for transfer, but outside the browser it often has nowhere to go. The decoded pixels, width, height, and alpha channel all survive the conversion. 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 any PDF reader can open, and Compress PDF takes the size back down when it matters. Size breakdown shows which pages carry the weight before you compress.

When should I convert WebP to PDF here?

This WebP to PDF converter is free with no account needed. The browser decodes each WebP and the PDF is written in this tab, so no file content reaches a server: usage data events carry only action names, counts, sizes and durations. Files are held in memory on your device, so very large sets depend on what your browser can hold.

Sending web-saved images to someone who cannot open WebP. When an email client or reader refuses WebP, a PDF page is the version other people can open without installing anything.

Archiving product or marketing images. WebP files saved from a website keep their quality when placed in a PDF, which any client or stakeholder can review without a browser.

Submitting images to a portal that accepts PDF only. When a portal accepts PDF but not WebP, convert your files here and download one PDF that meets the requirement.

Printing web graphics. When a print shop asks for PDF instead of WebP, the converted pages carry the decoded pixels and transparency into print.

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.

WebP to PDF frequently asked questions

Are my WebP files uploaded to a server?
No. The WebP decoder, PDF writer, and all output checks run in this browser tab. No file content leaves your device; usage data events carry only action names, counts, sizes and durations.
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.
Can I mix portrait and landscape WebP files in one PDF?
Yes. Fixed paper sizes turn automatically for landscape images. Match image gives every page the shape of its source image.
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.
Is there a file size or page limit?
No account is required and there is no queue. Files are processed in this tab and held in memory, so very large sets depend on what your browser and device can handle.
Does it preserve transparency?
Yes. The alpha channel is kept in the PDF. A PDF viewer normally shows the unpainted page beneath it as white.
What does the WebP to PDF verification check cover?
It reopens the completed PDF and checks the page count, every page size, and the pixel width and height of each embedded image. A failed result is not offered for download.
