WebP to PDF

Upload one or more WebP images, drag to reorder, choose the page size, and generate the PDF.

Not sure? Turn your internet off and try — it still works.

How it works

The PDF does not store WebP directly: the browser decodes each image and the tool converts it to PNG before placing it in the PDF. If the original WebP had compression loss (the most common case), that loss was already there; it is kept, and the conversion adds none. Since PNG is lossless, the PDF is usually larger than the source WebP files. It is useful for sending web images to printing and document-submission services that do not accept WebP. WebP transparency is kept in the PDF; since the page is white, transparent areas show as white in most viewers. The layout (A4, Letter, Auto and margin) is explained in Images to PDF.
