Photos into a PDF, PDFs into one

Two jobs that usually mean uploading private documents to a stranger's server. Both run here in your browser instead, and both let you drag things into the right order first.

Why this one

Order matters, and so do proportions

The two things most browser PDF tools get wrong: they merge in whatever order the file picker handed over, and they stretch photos to fill the page.

Photos keep their shape

Each image is fitted to the page at its own aspect ratio and centred, so a portrait snap is not squashed into a landscape box. Auto orientation gives each page the shape of its picture.

Drag into order

Both tools show a numbered stack you can drag, nudge with arrows, sort by filename, or prune. What you see is the order you get.

Documents stay private

Nothing is uploaded. Bank statements, contracts and ID scans are read and assembled inside the browser tab, so there is no copy on a server to worry about.

Sensible file sizes

Phone photos are resized before they go into the PDF. Three quality settings let you choose between an email-friendly file and a print-ready one.

Page setup that fits

A4 or US Letter with a margin of your choosing, or let each page take the exact shape of its image for a borderless photo book.

Honest about failures

If a PDF is encrypted or damaged, you are told which file and why, instead of a generic error after the whole batch has run.

How to use it

Three steps, either tool

Add your files

Drop images into the left card or PDFs into the right one. Add more at any time and they join the end of the stack.

Set the order

Drag rows, use the arrows, or sort by filename. For images, pick a page size, orientation and margin.

Build and download

Name the file and press the button. The finished PDF appears with its size, ready to save.

Questions

Frequently asked

Are my files uploaded anywhere?

No. Both tools read your files locally and build the PDF inside the browser tab. Nothing is transmitted, which is why they keep working if your connection drops after the page has loaded.

Why is my photo not filling the whole page?

Because it would have to be stretched to do so. Each image is scaled to fit the page at its own proportions and centred, leaving space at the sides or the top when the shapes do not match. To remove that space, set page size to "Fit each page to the image" and the margin to none.

What order will my files appear in?

Exactly the order shown in the stack, top to bottom. File pickers do not always hand files over in the order you selected them, so check the stack before building — you can drag rows, use the arrow buttons, or sort by filename.

Can it merge password-protected PDFs?

A PDF that is restricted against editing or printing will usually merge fine. One that needs a password just to open cannot be merged, because its contents cannot be read — remove the password in a PDF reader first, then merge.

How large will my PDF be?

For images, roughly 150 KB per page on Small, 400 KB on Standard and over a megabyte on High. Merging PDFs adds the source files together, so the result is about the sum of their sizes.

Does merging reduce quality?

No. Pages are copied across intact, so text stays selectable and images are untouched. Only the images-to-PDF tool re-encodes anything, and that is controlled by the quality setting.
