MyPDFHero’s merge tool is tuned for people stitching receipts, contracts, coursework, and onboarding packets. Instead of installing a heavy desktop app, drag up to ten PDFs and keep their order with simple arrows or drag handles. The engine preserves bookmarks, hyperlinks, and page sizes so the final document feels as if it was authored in Acrobat—minus the subscription.
It also handles mixed sources such as scanned pages, exported slide decks, and e-signed agreements. Because the merger runs on the same secure infrastructure as our compressor, files are encrypted in transit and deleted shortly after export. The output arrives in seconds, ready to email, print, or re-upload to e-sign platforms.

Merge PDF FAQs
How do I merge PDF files without losing quality?
Upload them to MyPDFHero, keep each file under 20 MB, arrange the order, and export. We never downsample pages, so images and annotations stay intact.
Can I merge password-protected PDFs?
Unlock the file first in your PDF viewer, then re-save it without a password before uploading. Once unlocked, MyPDFHero can merge it with the rest.
Does the tool work on Windows, Mac, and mobile?
Yes. The merger runs entirely in the browser, so any device with Chrome, Safari, or Edge can upload and export files.
Is there a limit to how many PDFs I can combine?
You can merge up to ten PDFs per session. After you download the combined file, repeat the process with more batches if needed.
Will page numbers or bookmarks break?
No. Existing pagination and bookmarks remain untouched because we simply concatenate the PDFs instead of rasterizing them.
Can I merge PDFs on my phone?
Definitely. The interface is optimized for mobile so you can select files from iOS Files, Android Downloads, or cloud storage apps.
How long do you keep merged PDFs?
Just long enough to let you download them. Files are purged automatically minutes after completion for privacy.
Does MyPDFHero add branding to the merged file?
No. The final PDF is free of watermarks or footers, making it professional enough for clients and government offices.
