Need help?Convert PDF to WebP Online
Turn each page of a PDF into a WebP image — a modern web format that is roughly 25-34% smaller than JPEG and 26% smaller than PNG at matching quality, per Google's WebP study. It is ideal when you need lightweight page previews, thumbnails, or document images for a fast-loading website. The output is a flat raster image of each page, so the text becomes part of the picture rather than selectable copy.
How to Convert PDF to WebP
- Upload Your PDF File: Drag and drop your PDF onto the page or click "Add Files." Multi-page PDFs produce one WebP image per page, returned together in a ZIP.
- Set Conversion Quality (DPI): Pick the render resolution under Conversion Quality. 72 or 96 DPI keeps files tiny for web thumbnails; 300 DPI (the default) is sharp enough for on-screen reading; 600 DPI suits archival or fine detail.
- Choose Color and Lossless (Optional): Set the page background under Color (White by default, since WebP fills transparent PDF areas). Leave Lossless on "No (Recommended)" for the smallest files, or switch it to "Yes" to keep every pixel exact.
- Convert and Download: Click Convert and download your WebP images. No sign-up, no watermark.

Frequently Asked Questions
Why is the text in my WebP not selectable?
WebP is a raster image format, so this conversion renders each PDF page as a flat picture — the letters become pixels, not searchable text. If you need the words back, run OCR on the WebP, or keep the original PDF for copy-paste and use the WebP only for display.
How are multi-page PDFs handled?
Each page becomes its own WebP file. A 10-page PDF produces 10 images, delivered together in a single ZIP so page order is preserved. There is no merged "long strip" output; convert to a single PDF first if you want one combined file.
Should I leave Lossless off for smaller files?
Yes, for most web use. Lossy WebP (Lossless set to "No") gives you the format's headline 25-34% size advantage over JPEG. Turn Lossless on only when you need pixel-exact text or diagrams and can accept a larger file — lossless WebP still lands about 26% under an equivalent PNG.
What happens to transparent areas in the PDF?
By default they are filled with the Color you pick (White is preselected), because a flattened page usually looks best on a solid background. WebP itself supports an alpha channel, but if true transparency matters more than file size, convert PDF to PNG instead and choose "Unchanged."
What DPI should I pick for a website thumbnail?
In our testing, a US-Letter page rendered at 96 DPI lands near 900x1160 px and a few dozen KB as lossy WebP — plenty for a card preview or modal. Step up to 150-300 DPI only when readers will zoom into the page text. Need a different target instead? Convert PDF to JPG for the widest-compatibility raster.
