What Image collage to PDF does

Image collage to PDF takes a set of JPG, PNG or WebP images and packs them automatically into A4 pages, in a grid whose density you control with two sliders. Every image keeps its proportions, nothing is cropped, and the pages fill up in the order you added the files. The PDF is generated in your browser, so there is no upload and no limit on the number of images.

It is the fast way to put many pictures on few sheets: the photos from a site visit, the screenshots of a bug report, the pages of a photographed notebook, the items of a small inventory. Instead of placing each image by hand, you set how much space you want between them and how small they may get, watch the live preview, and generate.

How to create a collage PDF

  1. Add your images. The order in which you add them is the order in which they are placed.
  2. Press Create collage PDF to open the layout screen.
  3. Set Padding, from 0 to 72 points, which is both the outer margin and the space between images. The default is 18 points.
  4. Set Minimum image size, from 40 to 300 points. A larger value means fewer images per page and therefore more pages; the default of 120 points fits up to 20 images on a page.
  5. Check the Live preview, which shows the first three pages and tells you how many images will land on how many pages, then press Create collage PDF. The file is downloaded with the suffix _collage and a timestamp.

How the layout works and its limits

The two sliders decide how many columns and rows fit on an A4 page. The images are then taken in groups of that size, and on each page the grid is stretched to use the full width and height available. Each image is scaled to fit its cell without cropping and centred in it. On the last page, which is usually not full, the cells and therefore the images come out larger than on the others.

Privacy: the collage is built on your computer

The preview is drawn from local copies of your images and the PDF is assembled by a library running in your browser tab. No image is uploaded, no preview is sent anywhere and no third-party script is loaded. The only download is OléPDF's own code from its own domain. Your photos exist only where you stored them.

That makes it usable for pictures of people, private property or unpublished work without thinking twice.

Typical uses

Frequently asked questions

Is the collage tool free?

Yes. Creating collage PDFs from any number of images is free and unlimited, with no account, no watermark and no batch restriction.

Are my images cropped or distorted?

No. Each image is scaled to fit its cell while keeping its proportions, and it is centred in the cell. Nothing is cut off.

How do I get more images on a page?

Lower the Minimum image size and, if you want, the Padding. With padding at 0 and the minimum at 120 points, up to 28 images fit on a page; the preview updates as you move the sliders.

Can I add names or numbers under the pictures?

Not in this tool. The Contact sheet tool builds a captioned, numbered grid with paper and orientation options; the collage tool focuses on packing images fast.

Which formats can I use?

JPG, PNG and WebP, mixed freely. Other formats must be exported to one of these first.
