Order and rotation

Files are sorted by name (01, 02 …) when added. Use ↑ ↓ to move them and ↻ to rotate a landscape scan in 90° steps. Rotation applies to the whole file.

Does the file get bigger?

Pages are copied as they are, so the merged file is usually about the sum of the originals. Fonts repeated across files can add a little. To shrink an image-heavy document, export it with PDF → image at a lower quality and rebuild it with images → PDF.

Password-protected PDFs

They will not open. A viewing password should only be removed by someone entitled to read the document, so remove it in the original program first.

Forms and signatures

Fillable form fields and digital signatures may not survive page copying. If a document is signed, check the signature area after merging.

Frequently asked

Are my documents uploaded?

No. Reading and rebuilding the PDF happens inside your browser. It keeps working if you go offline after the page has loaded.

How many files can I merge?

There is no limit. Several very long documents can use a lot of memory on a phone, though.

Can I interleave individual pages?

This tool orders whole files. Extract the pages you need with Split PDF first, then merge.
