Why merge PDFs in your browser?
Most "free" PDF mergers upload your documents to a server, process them there, and often add a watermark or a paywall once the file gets large. meldpdf does the whole job on your own device. That means contracts, invoices, bank statements and other sensitive documents never travel across the internet — which is both faster and far more private.
Common uses
- Combining scanned pages into a single document to email or print.
- Joining a cover letter and CV into one PDF for a job application.
- Merging monthly invoices or receipts for bookkeeping.
- Assembling chapters or handouts into one file.
Frequently asked questions
Is there a limit on how many PDFs I can merge?
No fixed limit. Because processing happens on your device, very large jobs depend on your computer's memory rather than a server quota.
Will merging reduce the quality of my PDF?
No. Pages are copied exactly, so text stays selectable and images keep their original resolution.
Do you keep a copy of my files?
No. We have no server that receives your files — everything stays in your browser. See our privacy policy.
