Save Picture as PDF from a Website: WebP and Screenshots

To save a picture as PDF when it comes from a website, first save the image or take a screenshot, then convert that file. The surprise is the format: sites can serve WebP or AVIF instead of JPG or PNG, and some tools reject them. Check the file extension after saving, and pick the route that fits.

Save picture as PDF: what the file really is

MDN’s guide to image formats names the formats used on the web today: APNG, AVIF, GIF, JPEG, JPEG XL, PNG, SVG and WebP. It says WebP and AVIF generally compress better than PNG, JPEG and GIF, which is why many sites serve them. If you save an image from a page, the saved file may carry one of those formats, so look at the extension. In a test on 2026-10-24, img2pdf 0.6.3 converted a WebP image to PDF without trouble; the PDF image was stored as decoded, Flate-compressed pixels, and the PDF was larger than the WebP file. Other tools may reject WebP, and image to PDF shows the behaviour of each format.

Two routes to save a picture as PDF

1. Save the image, then convert it. Open the saved file in a tool that reads its format and use print to PDF or a converter. If the tool refuses the format, convert the picture to PNG or JPG first, or use the screenshot route.
2. Take a screenshot of the picture. Apple says Mac screenshots are saved as PNG files by default, and the Windows Snipping Tool saves snips to a Screenshots folder and lets you choose a file type in the Save As dialog. A screenshot captures what is on screen, so it is limited to screen resolution; the saved image may be smaller than the original.

Either route ends with a PNG or JPG that any PDF tool reads. The print dialog route is explained in save photo as PDF.

Check the licence before you share

Having a copy of a picture does not give you the right to use it. Check the licence or ask the owner before you send a picture you saved to other people, put it into a document that you publish or print it commercially. For pictures that are yours, such as logos and artwork, make a picture to PDF covers transparency and sharpness, and PNG to PDF covers the PNG route in detail.

FAQ

Why can’t I convert the picture I saved from a website?

It may be WebP or AVIF, which some tools do not read. Check the file extension and convert it to PNG or JPG, or take a screenshot.

Does a screenshot lose quality compared with saving the picture?

It can, because a screenshot captures at screen resolution. Saving the original file keeps its full size.

Can I print a whole web page to PDF instead?

Yes, Chrome’s print dialog has a Save as PDF destination. That produces a page layout, not the picture on its own.
