WebP gives you the same page picture at roughly half the size of a PNG. Pick your pages, resolution and quality, and the conversion runs here in this tab.

WebP was designed to replace both PNG and JPG on the web, and for page images it usually wins on size. A typical A4 page rendered at 150 dpi might be 180 KB as a PNG and 70 KB as a WebP that looks the same on screen. On a site with a dozen page previews, that is the difference between a page that loads instantly and one that does not.
WebP also keeps transparency, which JPG cannot, so it covers both jobs with one format. The trade-off is that the quality slider is lossy: at low settings fine print softens and thin lines pick up faint fuzz. For text-heavy pages, keep the quality at 85% or above and you will not see the difference.
There is one place PNG still wins outright: an image that will be edited and re-saved several times. Every lossy save throws a little more away, so for a working file that will go through several rounds of changes, convert to PNG and only move to WebP when the picture is final and about to be published.
Two settings decide what you get. Resolution controls how many pixels the page becomes: 150 dpi makes an A4 page about 1240 by 1754 pixels, which is comfortable on any screen, and 300 dpi doubles that in each direction for printing. Quality controls how hard the picture is compressed once it has been drawn.
The useful rule is to set the resolution from how the image will be used, and the quality from how much detail the page holds. A page of plain text survives a lower quality than a page with photographs on it. If a file still looks too large, lowering the resolution usually helps more than lowering the quality, because it removes pixels rather than detail.
It is worth converting one page first and looking at it properly, at the size it will actually be displayed, before converting a hundred. Judging quality on a zoomed-in view leads people to pick settings far higher than they need, and the files end up three times larger for a difference nobody will ever see.
Every current browser can show WebP, and has been able to for years. Encoding is a different matter: the tool needs your browser to write WebP, not only read it. A handful of older browsers can display WebP but not create it, and some canvas implementations quietly hand back a PNG when asked for a WebP instead.
Rather than give you a PNG with a .webp name on it, this page checks whether real WebP encoding is available before it starts, and says so plainly if it is not. If you see that message, use PDF to PNG or PDF to JPG instead; the pages will be identical, only larger.
If the images are destined for a website and you want to be careful about older visitors, the usual approach is a picture element that offers WebP first and a JPG as the fallback. That way modern browsers take the small file and everything else still sees an image.
Files are not uploaded - everything happens in your browser. The PDF is read by JavaScript in this tab, each page is drawn on a canvas, and your browser encodes the WebP in memory. No copy of the document is sent to us or to anyone else, and there is nothing for us to delete afterwards because nothing arrived.
The practical side of that is a tool with no queue, no file-size rules imposed by a server, and no account. The only download is the rendering code itself, fetched once and only after you have chosen a file.
It also means the limits you meet are your device's limits, not ours. A long document at 300 dpi will be slower on an old phone than on a laptop, and the tool works through the pages one at a time precisely so that a modest phone keeps responding while it does.
If you already have WebP images and need a document, WebP to PDF puts them in order on PDF pages, which is the reverse of this tool. If you need the images in a format an older program will accept, WebP to JPG does that conversion, also in the browser.
And if your real problem is a PDF that is too big to send, PDF Compressor shrinks the document itself rather than turning it into pictures, which keeps the text selectable.
Choose the PDF here, set the resolution and quality, and press Convert. Each page becomes a WebP image you can download.
For page images, usually by 30 to 60 per cent at a quality nobody can tell apart on screen. The saving is largest on pages with photographs or shading.
In a browser, yes. Some older desktop programs still cannot, so use PNG or JPG if the file is going to someone who may have old software.
Keep it at 85 to 95% for pages with text. Go lower only when the file size matters more than crisp lettering.
Yes. Type something like 1-3,8 in the pages box. Leave it empty to convert everything.
Yes, and so does this tool. Tick the transparency option and empty areas of the page stay see-through.
No. The whole conversion runs in your browser, which is why it works without an account and keeps working on a poor connection.
