Turn .webp files saved from websites into one PDF.
On your device. No watermark. No sign-up.
This tool is processed locally with JavaScript inside your browser tab. The document is not uploaded, stored or seen by a server, which makes it suitable for contracts, invoices, CVs and medical or financial records.
WebP is the format most websites serve now, because it is smaller than JPG and PNG at the same visible quality. When you save an image from a web page in Chrome or Edge, you often get a .webp file on your disk.
Many PDF tools and form uploads do not accept it. This page takes .webp directly and builds the PDF on your device, so nothing has to be converted by hand first.
A PDF cannot store WebP. Your browser decodes the WebP, the picture is redrawn on a canvas, and that canvas is stored as a PNG inside the PDF.
The redraw is lossless from the pixels your browser decoded, so nothing is thrown away a second time. But PNG is a storage format, not a compressor like WebP, so the PDF is usually larger than the .webp files you started with — a 300 KB WebP photo can easily become a page several times heavier.
If the result is too big for an email or a portal, run it through Compress PDF afterwards. That is the right order: convert first, compress second.
An animated WebP works like a GIF: several frames in one file. A PDF page is a still picture, so only the first frame is used and the rest are ignored.
If the animation matters, export its frames as separate images and add them in order — each frame becomes its own page, which reads like a flip book in a PDF viewer.
WebP supports transparency, and a PDF page does not. Transparent areas show the white page behind the image, so a picture that floated over a coloured background on a website arrives on white.
A lossy WebP has already discarded detail before you ever see the file. Converting it does not restore that detail, and it does not damage it further: the PDF holds exactly what the browser decoded.
Some sites save the file with no extension at all, or with a name that the file picker hides. Rename it to something.webp and add it again.
A file that is really a JPEG with a .webp name still works, because the browser reads the content rather than the name. The same is true in reverse: a .jpg that is really a WebP opens fine in Images to PDF.
Fit to each image makes every page as large as its picture, one pixel to one point. A4 and Letter give every page the same size, with the image scaled to fit and centred.
Use the arrows to set the order, one image per page. Each run makes one PDF. For printing, choose A4 so the pages are the size a printer expects.
The decoding and the PDF are done inside this browser tab. Your WebP files are never sent to a server, so it is safe for anything you saved from a private page. After your first visit the tool also works offline.
Yes. There is no account, no daily limit and no watermark on the PDF.
No. The conversion runs in your browser and the .webp files never leave your device.
No. The WebP is decoded once and stored losslessly as a PNG in the PDF. Detail the WebP already lost cannot come back, but nothing is lost a second time.
WebP compresses hard; PNG does not. The PDF stores the decoded pixels losslessly, so it is usually several times larger. Compress the PDF afterwards if size matters.
Only the first frame is used, because a PDF page is a still picture. Export the frames separately if you need all of them.
It shows the white page behind the image. A PDF page cannot be transparent.
Not on this page, which takes WebP only. Use Images to PDF to combine WebP, JPG and PNG in one PDF.
Yes. Add them all, set the order with the arrows, and press Convert. Each image becomes one page.
The closest tool here is Resize Image to KB, which always outputs a JPG under a size limit you choose. An image editor can also save a WebP as JPG directly.
Yes. Choose the files from your gallery or Files app. Large images can take a few seconds on an older phone.
