WebP to PDF Converter

WebP is the image format most websites now serve, but it is awkward to print, attach to an application or archive. This tool places each WebP image on a PDF page — at its own size or fitted to A4 or Letter — and builds one PDF or one per image. Transparent images are stored losslessly with their transparency; photos can be stored as JPEG for a smaller file. Conversion happens in your browser.

How to use this tool

1. Select the WebP images in the order you want the pages.
2. Choose one PDF or one PDF per image.
3. Pick the page size and orientation, and a margin if you will print it.
4. Choose how images are stored: automatic, always lossless, or always JPEG.
5. Download the PDF.

Formula

Page size "Same as each image" uses 96 pixels per inch, so a 1200 × 800 px image becomes a 900 × 600 pt page (12.5 × 8.33 in). On A4 or Letter the image is scaled by min(available width ÷ width, available height ÷ height), never above 100% unless you tick "Enlarge", and centred.

Lossless storage keeps every pixel (RGB compressed with Flate, plus a separate alpha mask when the image has transparency). JPEG storage fills transparent areas with white.

Example

Two product pictures of 1000 × 1000 px with transparent backgrounds, converted with "Automatic" storage and A4 portrait, give a 2-page A4 PDF: each picture is 750 × 750 pt at full size, so it is shrunk to fit the 595 pt-wide page and keeps its transparent background over the white page.
