WebP to PDF, decoded in your browser

Many websites serve their pictures as WebP, so images saved from a page often end up as .webp files that not every app will open. Here your browser decodes each one, draws it at its full pixel size, and that drawing is what goes into the PDF, stored losslessly.

Lossy WebP gets its small size by throwing detail away. The PDF keeps exactly what the WebP shows, but without that trick, so expect the PDF to be larger than the WebP files you started with.

Each WebP lands on a page sized for that picture alone, so a square icon and a wide banner in the same batch each keep their own shape instead of being forced onto a shared canvas.

Three steps

How to convert WebP to PDF

  1. Add the WebP files

    Drop them in. You can keep dropping more and they join the list.

  2. Arrange the pages

    Drag the thumbnails into order, then pick a Page Size and a Page Orientation.

  3. Convert to PDF

    Click Convert to PDF. Each WebP becomes one page of a single PDF.

Format details

What a WebP brings into the PDF

  • First frame only

    An animated WebP contributes its first frame. The page shows a still, not the animation.

  • Transparency kept

    See-through areas stay see-through in the PDF and show the white page behind them.

  • Lossless WebP stays exact

    A lossless WebP arrives with identical pixels, so graphics and screenshots saved as WebP lose nothing.

  • Named after the first file

    The PDF you download takes the name of the first WebP in your list, with the site's name added, whatever the batch size.

  • Every image, its own page

    Pages are sized one file at a time, so a batch of mismatched WebP files never forces a picture to stretch to match its neighbors.

  • One failure stops the batch

    If a single WebP cannot be read, the whole conversion stops with an error rather than skipping just that file, so no partial PDF is produced.

Going the other way?

Behind the button

Why WebP goes through a browser drawing, not a direct copy

A PDF page can only hold a JPEG or an uncompressed image directly, and WebP is neither, so the file cannot be copied in the way a JPG can. Instead your browser opens it like a normal picture and redraws it onto a hidden canvas, and that redrawing, not the original .webp bytes, is what the PDF stores.

That is also why a WebP that will not open in your browser cannot be converted: there is no separate reader behind this tool, only the one already built into it. A file with a .webp name that is actually something else fails the same way.

The redraw happens once per file and produces one image per WebP, so a still picture converts as cleanly as a photo, while an animation only ever contributes the frame the browser shows the moment it finishes loading.

Run it through Compress PDF, which trades some image quality for a smaller file.

Yes: choose Auto (Match Image) under Page Size. Each image pixel then counts as one point, 1/72 inch, so the page wraps the picture with no border.

The tool relies on your browser to decode the file. A damaged file, or one that is not really a WebP despite its name, can't be read and stops the conversion with an error.

Use Images to PDF for those: it takes any image format your browser can display, and current browsers display AVIF.

No. The browser draws the same colors it would show on screen, and those pixels are stored in the PDF exactly as drawn, with no color shift from the conversion itself.

Yes. Each file gets its own page sized for that picture, so a square thumbnail and a wide screenshot can sit one after another without either being distorted.

One. Every picture you add becomes a page in the same PDF, in the order shown by the thumbnails, so a batch of files always downloads as a single document.

Auto (Match Image) already sets the page to the picture's own width and height, so there is no fixed sheet left to turn sideways. Orientation only changes something on A4, Letter or Legal pages.
