Frequently asked questions
Is this PDF merger really free?
Yes — merge up to 20 PDFs (100 MB each, 500 pages total) as often as you like. No account, no watermark, no email required.
Are my files uploaded anywhere?
No. Merging runs entirely in your browser. Your PDFs never leave your device, which makes it safer than server-side tools for sensitive documents.
Will merging reduce quality?
No. Pages are combined losslessly in the order you set — text stays selectable and images keep full quality.
How do I change the page order?
Use the up/down arrows on each file to reorder before merging. Files merge top to bottom, exactly as listed.
Can I remove a file I added by mistake?
Yes — press the ✕ button on any file to drop it from the merge, or Clear all to start over.
Can I combine single-page scans into one PDF?
That's the most popular use: scan each page, drop all the one-pagers here in order, and merge. Then optionally compress the result if it's too big to email.
What do I do after merging?
Download the combined PDF, then open it in SimpleSign on iPhone to sign, annotate, or back it up to Google Drive.
