Merge PDF files

Combine PDFs into a single file and put them in the right order. Pages are copied exactly — no quality loss. Your file never leaves your device. The tool runs entirely in your browser — nothing is uploaded, stored, or seen by us.

FramePDF combines, reorders, rotates and removes pages directly on your Android phone. Changes stack up on a copy, so your original is never touched — and nothing is uploaded.

When you need one PDF instead of many

Forms often have a single upload slot for things that come as separate files — a marksheet for each semester, the front and back of an ID card, or a certificate plus its annexure.

Merging keeps every page at its original quality. If the merged file is then too big for the portal, run it through Compress PDF afterwards.
