WebP to PDF Converter
Turn WebP images into a single PDF. Choose the page size, put the images in order, and decide whether each page should be stored losslessly as PNG or compactly as JPEG.
Your files are processed locally in your browser tab. They are not uploaded to this server and they are not sent to any third party.
Drag a row to reorder it, or focus a row and press Alt with the up and down arrow keys.
Page setup
A PDF cannot store WebP, so each image is decoded by your browser and then written into the PDF as PNG or JPEG. Nothing is uploaded while that happens.
Your PDF is ready
How to convert WebP images to PDF
- Add one or more WebP images.
- Drag the rows into the order you want the pages to appear in.
- Choose a page size, and decide whether pages should be stored as PNG or JPEG.
- Press "Create PDF" and wait for the progress bar to finish.
- Download images.pdf.
Why the images are re-encoded, and what that costs
WebP is a modern format that PDF does not support. The specification allows JPEG, PNG, JPEG 2000 and a few others; WebP is not among them, and a PDF containing a WebP stream would simply fail to open in most readers. So this tool decodes each WebP in your browser and stores the result as something PDF does support. There is no way around that step, and any tool claiming to embed WebP directly in a PDF is either re-encoding it too or producing a file that will not open.
- Decoding is exact: the browser reproduces the WebP pixels faithfully.
- PNG storage is lossless, so the PDF holds the picture as decoded.
- JPEG storage re-encodes at 92 percent quality: much smaller for photographs.
- Transparency survives PNG storage and is composited onto white for JPEG.
- Images wider than 4000 pixels are reduced, and the list says which ones.
What this tool does not do
- It does not embed WebP directly: PDF does not support it, so re-encoding is unavoidable.
- It does not convert JPG, PNG, GIF, AVIF or TIFF. Use the matching tool for those.
- It does not run OCR, so a PDF made from images stays an image.
- It does not compress beyond the PNG or JPEG choice.
- It cannot decode a WebP variant your browser does not support; such a file is reported by name.
Frequently asked questions
Is the image stored in the PDF as WebP?
No, and this is worth being precise about. The PDF format cannot hold WebP; it supports JPEG and PNG only. So each image is decoded and then stored as one of those. Choosing PNG keeps the picture losslessly, so the version in the PDF is the version that was decoded. Choosing JPEG makes a much smaller file for photographs at the cost of some fine detail and all transparency.
Which should I choose, PNG or JPEG?
If the WebP contains screenshots, diagrams, text or transparency, choose PNG. If it contains photographs and the file size matters, choose JPEG. The result panel always states which one was used and reports the real output size.
Does the conversion reduce quality?
The decode is exact: the browser reproduces the WebP pixels. Storing as PNG adds nothing further, so the PDF holds the same picture. Storing as JPEG re-encodes, which is very slightly lossy, though at 92 percent it is hard to see.
Will my images be stretched?
No. Each image is scaled by a single factor until it fits inside the page, so its proportions never change. A tall screenshot leaves white space at the sides rather than being distorted.
What page sizes are available?
A4, Letter, or "page sized to the image", which makes each page exactly the size of its image with no margins. The last option is the one to pick for screenshots or when the PDF is really a container for pictures.
Which WebP variants are supported?
Whatever your browser can decode, which in practice covers lossy, lossless and alpha WebP. If a file cannot be decoded, it is reported by name when you add it rather than failing silently in the middle of the job.
Can I use a JPG or PNG here too?
No, this tool accepts WebP only and says so. Use JPG to PDF or PNG to PDF for those formats; each tool states exactly what it accepts.
