How to merge PDF files on your phone
Many forms allow only one upload for “all documents”. You don’t need a laptop or an app to combine PDFs — your phone’s browser is enough.
Merge my PDFs Free, no sign-up. Files deleted after 24 hours.
Before you merge
- If some documents are photos, turn them into a PDF first with JPG to PDF.
- If any PDF is password-protected, unlock it first.
- Rename files with numbers (1 10th, 2 12th…) so they sort in the right order.
After you merge
Check the total size. If the form has a limit such as 2 MB or 500 KB, compress the merged PDF to that size.
Step by step
- Open Merge PDF in your phone’s browser.
- Tap “Choose files” and pick all the PDFs.
- Drag them into the right order.
- Press Merge and download one PDF.
- Compress it if it is over the upload limit.
