Guide
Collecting images saved from websites into one PDF
Right-click a picture on almost any modern website, choose Save image, and you get a .webp file. That’s because websites switched to WebP to load faster. The format is fine for browsing, but plenty of software still refuses it: older versions of Word and PowerPoint, many print dialogs, some school and government portals. Gathering the images into a PDF gives you one file that opens and prints everywhere.
Building a reference PDF
A PDF of images is a handy way to keep visual research together:
- Study notes: diagrams and figures from course websites, in lecture order.
- Mood boards: colors, interiors, products or outfits for a project.
- Recipes and instructions: step photos saved from a blog.
- Print-outs: a set of images to print on one go.
Add all the files, then drag them into the order you want; the first file becomes page 1.
Page layout
A4 or US Letter creates printable pages, each image scaled to fit and centred, with landscape pages for wide images when orientation is on Auto. A small margin looks tidy; None makes images as large as possible. Same as image makes each page the size of the picture, which suits viewing on screen.
Quality and transparency
WebP images on the web are usually photos, so Smaller file is selected by default and pages are stored as high-quality JPEGs. Choose Lossless for diagrams, charts and screenshots, where crisp lines and text matter.
Logos and stickers often have transparent backgrounds. Lossless keeps them transparent (white on the page) or fills them with a color you choose; Smaller file always fills them, with white unless you pick another color.
Animated WebP
WebP can store animations like a GIF. A PDF can’t animate, so the first frame is used. To keep the animation, convert it with the GIF Maker or keep the original file.
Respecting copyright
Saving images for personal notes is generally fine; republishing them in a document you share is a different matter. Check the image’s license before distributing a PDF built from someone else’s pictures.
Everything happens in your browser
The images are decoded by your browser and the PDF is assembled locally. Nothing is uploaded, which also means there are no file-count limits and no waiting for uploads.
Related tools
To convert WebP files into regular images instead, use WebP to PNG or the Image Converter. For newer AVIF images, see AVIF to PDF. For photos from a phone, JPG to PDF, and if the result is large, Compress PDF.
A worked example: lecture diagrams
A student collects twelve diagrams from an online course for revision.
- Save each diagram from the course pages; they arrive as
.webpfiles. - Add them here and drag them into the order of the course.
- Switch to Lossless, because diagrams have text and thin lines, and choose A4 with a small margin.
- Create the PDF, then print it two pages per sheet with N-Up PDF to save paper.
Troubleshooting
- A file won’t open: it may not really be WebP. Some sites serve AVIF or JPG with a
.webpname; try AVIF to PDF or JPG to PDF. - The PDF is large: keep Smaller file for photos, or compress the PDF afterwards.
