How it works
Add your images
Drag and drop, paste, or pick files. They upload over an encrypted connection.
Pick a quality or a target size
Use the quality slider, or tell it exactly how many KB or MB you need.
Download
Save each file, or grab them all at once as a ZIP.
Websites often need a picture of a document: the cover of a report beside its download link, the first page of a menu, a preview of a brochure, a certificate in a gallery. WebP is the format to make that picture in. It is displayed by every current browser, and for a page of text and graphics it is markedly smaller than a JPG of the same clarity.
Add a PDF and its first page is drawn at 200 dots per inch on a white sheet, about 1650 by 2340 pixels for A4, and saved as a WebP at quality 85. When the PDF has several pages, a page number appears in the editor; change it and that page is drawn in its place. One page is converted at a time.
PDFs are uploaded over an encrypted connection, drawn on our own servers and deleted within one hour. Password-protected PDFs are refused; remove the password in a PDF program first.
Size the picture for its place on the page
The full rendering is far larger than a preview needs. A thumbnail in a list of documents is shown 200 to 300 pixels wide; a preview beside a download button perhaps 600. Open Resize and enter the width the layout uses, doubled if you want it crisp on high-density screens. A 600 pixel preview of a text page is typically 20 to 40 KB as WebP, small enough to load instantly.
Keep the large version only where visitors are meant to read the page from the image itself, and even there 1200 pixels of width is plenty for a screen.
Lossy for covers, lossless for small print
At the starting quality of 85 a WebP handles mixed pages well: photographs, coloured areas and headlines look clean. Small body text is the weak spot of every lossy format, WebP included. Thin strokes pick up a slight softness, and coloured text loses a little of its edge.
If the image has to be read, and not just recognised, switch the mode to Lossless. The page is then stored exactly as it was drawn, and because a printed page is mostly flat white, the lossless file is often no bigger than the lossy one. For a cover or a thumbnail, lossy at 75 to 85 is the lighter choice.
A picture of a page is not the document
It is tempting to publish documents as images because images are easy to place. Resist that for anything people need to use. The text in a picture cannot be selected, searched or enlarged cleanly. Screen readers cannot read it aloud. Search engines index it poorly, so the content of your report does little for your site.
The good pattern is both together. Show the WebP as a preview, give it an alt text that says what the document is, and link it to the PDF itself. Visitors see what they are about to open, and the real document remains available to people and to search engines.
Frequently asked questions
Can I convert all pages of the PDF at once?
No. One page is converted for each conversion. Choose the page number in the editor, download, and choose the next.
What resolution does the WebP have?
The page is drawn at 200 dpi, about 1650 by 2340 pixels for A4. Use Resize to make the preview size you need.
Is the background transparent?
No. A PDF page is drawn on white, the way it would print.
WebP, PNG or JPG for a PDF page?
WebP for a website, since it is the smallest. PNG when the image must open in older software. JPG when an upload form asks for it.
Will the text in the image be searchable?
No. The page becomes pixels. Keep the PDF available alongside the image if the text matters.
Does it work with scanned PDFs?
Yes. A scanned page is drawn like any other, and as a photograph of paper it suits lossy WebP well.
