About images to pdf

Images to PDF combines pictures into a single PDF document. Use it to turn a set of scans into one file for a form, to submit photographed evidence as one attachment, or to archive a set of images in a document format that prints predictably.

Page size and margin are the two settings that decide whether the result looks professional. Fitting each image to a page makes them all the same size, which looks consistent and is what most forms expect. Choosing a fixed page size such as A4 with a small margin looks tidier still, because the pages are genuinely document pages rather than images floating in space.

On compression: images placed into a PDF are normally stored losslessly, which produces an enormous file. Turning JPEG compression on re-encodes each page, which typically cuts the file size by 80 percent or more with no visible difference at print quality. Leave it off only when you are archiving images that must stay bit-identical, such as medical or legal scans.

Frequently asked questions

Why is my PDF so large?

Because images are stored inside it without compression by default. Turning JPEG compression on usually reduces the file by 80 percent or more with no visible difference at print quality.

Should I compress the images in the PDF?

Yes, for almost every practical purpose including scans and photographs. The visible quality is indistinguishable at print sizes. Leave it off only for legal or medical archiving where the images must stay bit-identical.

What page size should I choose?

Fit each image to a page if you are unsure, since it gives consistent results whatever the source. Choose A4 or Letter if the document needs to match a specific paper size for printing.

Can I reorder the pages?

Yes, drag the files in the list. The order you leave them in becomes the page order.

Does this reduce the image resolution?

No. Pages are placed at their native pixel resolution. The file grows large simply because a full page of image data is a lot of data.

Are my images uploaded?

No, the PDF is assembled in your browser and downloaded directly.
