Check the destination first
WebP is the most efficient of the three formats and the least universally accepted. Every current browser reads it; some older desktop software and upload forms still do not. Confirm before you commit.
Add the PDF
Single-page files are converted in your browser. Multi-page files are zipped server-side, one image per page.
Convert
Pages render at about twice their nominal size and are encoded as WebP, which typically lands 25–35% below the equivalent JPG at comparable quality.
Compare against JPG if size is the goal
Convert the same page both ways and look at the two file sizes. On photographic pages the WebP advantage is largest; on flat text pages it narrows.
Use it on the web
This format exists for web delivery. On a page carrying several document images the saved bytes are worth having, and every browser your visitors use will display it.
Do not use it as an attachment
If the file is going to a person rather than a website, send JPG. The efficiency is not worth the chance they cannot open it.
About the PDF to WebP Converter
WebP was designed to replace both JPG and PNG for web delivery, and on the technical merits it does. It compresses more efficiently than either, supports both lossy and lossless modes, and handles transparency. The only real question is whether whatever receives your file can read it.
How much smaller, in practice
At visually comparable quality, WebP typically produces files 25–35% smaller than JPG, and its lossless mode frequently beats PNG as well. The advantage comes from better prediction: it can reference nearby blocks when encoding a new one, where JPEG treats every block independently.
The gain is not uniform. It is largest on photographic content with lots of texture, and smallest on flat pages of black text on white, where JPG is already efficient and there is little for the smarter algorithm to exploit.
| Page type | Typical saving vs JPG |
|---|---|
| Photograph or colour scan | Largest — toward the top of the range |
| Mixed text and images | Solid, around the middle |
| Plain black text on white | Smallest — JPG is already compact here |
The support question, answered honestly
Every current browser — Chrome, Firefox, Safari, Edge — displays WebP, and has for years. On the web it is safe.
Away from the web it is patchier. Older versions of Windows Photo Viewer, some document management systems, a number of government and university upload portals, and various older design tools still reject it. It is also less well recognised by people: a recipient who receives a .webp attachment may simply not know what to do with it.
So the decision is about destination, not quality:
| Going to | Use |
|---|---|
| Your own website or app | WebP — the saving is free |
| A form or portal you do not control | JPG, unless it names WebP |
| A person, by email or chat | JPG |
| Long-term archive | PNG for fidelity, or keep the PDF |
Where the format came from
WebP was released by Google in 2010, built on compression techniques developed for video rather than still images — which is why it predicts so much better than a format designed in 1992. Its adoption was slow for years because Safari held out until 2020; since then it has been effectively universal in browsers, and it now carries a large share of the images on the web.
Single page or several
One page converts in your browser: no upload, no limit. Several pages return as a zip built on the server, so those conversions upload the file and face the 10 MB server limit. Split PDF first if that is in your way.
Frequently Asked Questions
How much smaller is WebP than JPG?
Typically 25-35% at visually comparable quality. The saving is largest on photographic pages with plenty of texture and smallest on plain black text on white, where JPG is already efficient.
Can everyone open a WebP file?
Every current browser can, and has been able to for years. Away from the web it is patchier — some older desktop viewers, document systems and upload portals still reject it. Use it for websites; send JPG to people.
Why is WebP more efficient?
It borrows techniques from video compression and can reference nearby blocks when encoding a new one, where JPEG treats every block independently. That better prediction is where the saving comes from.
Should I use WebP for a page of text?
Only if it is going on a website. WebP handles text better than JPG, but PNG is lossless and therefore sharper still, and JPG is more widely accepted. WebP wins on bytes, not on either extreme.
Is my PDF uploaded?
Not for a single page — that runs entirely in your browser. Multi-page conversions are uploaded so the zip of images can be assembled on the server.
Does WebP support transparency?
The format does, but pages here are rendered onto white. A document page with a transparent background looks broken in most contexts you would paste it into.
When was WebP introduced?
Google released it in 2010. Adoption was slow while Safari held out, which it did until 2020; since then browser support has been effectively universal.
Can I convert WebP back to a PDF?
Yes — the Image to PDF Converter accepts WebP. Be aware that each round trip through an image format costs quality, so keep the original PDF rather than rebuilding from images.
