Questions and answers
Is it safe to merge PDFs online with Pagestro?
Yes. Pagestro merges your files inside your browser, so they are never uploaded to a server. Nobody else can see them, and nothing is stored after you close the tab.
How many PDFs can I merge at once?
There is no fixed file count. Each file can be up to 100 MB and a merge can contain up to 300 pages. Very large jobs depend on your device’s memory.
Can I change the order of the files?
Yes. After adding files, drag the cards (or rows in list view) into the order you want before you merge.
Will merging reduce the quality of my PDF?
No. Pages are copied as they are, so text stays sharp and images are not recompressed. If the result is too large, run it through Compress PDF afterwards.
Can I merge password-protected PDFs?
Yes, if you know the password. Pagestro asks for it, opens the file in memory and then merges it. The merged PDF has no password.
Does it work on iPhone and Android?
Yes. Open the page in Safari, Chrome or Firefox, add files from your phone and download the merged PDF. There is no app to install.
Is Merge PDF really free?
Yes. Merging is free with no sign-up, no watermark and no daily limit.

Everything a merge should be
Built for the five-minute job you do between meetings.
Your files never leave your device
Pages are combined by your browser, so there is no upload, no server copy and nothing to delete afterwards.
Original quality
Pages are copied as they are. Text stays sharp and images aren’t recompressed.
Fast on any connection
Nothing to upload first, so the result is ready in seconds.
Works on your phone
Merge attachments from your mail app without switching to a laptop.
Drag to reorder
Card and list views make it easy to put twenty files in the right order.
Password-protected files
Enter the password once and the file is opened in memory before merging.
Free, with no watermark
Use it as often as you like. No sign-up, no daily limit and no logo stamped on your pages.
Private by design
Merged in your browser, never on our servers
Most merge sites upload your documents, process them on a server and ask you to trust that they’re deleted. Pagestro joins them right here in your browser instead, so contracts, payslips and medical forms stay on your device the whole time.
- No upload, so no copy on anyone’s server
- The joining happens in this browser tab
- Close the tab and nothing is left behind
Merge on your phone, where the files are
Got a scan, an invoice and a signed form as separate attachments? Open Pagestro in your phone’s browser, add all three and send one PDF back, without installing an app.
- Works in Safari, Chrome and Firefox on iOS and Android
- Pick files with your phone’s own file picker
- Saves the merged PDF straight to your phone
