Why pick Convertify for this?
Files stay on device
Convertify processes everything in your browser using JavaScript. Your file is never uploaded — confirm with DevTools → Network. That makes this safe for sensitive material like contracts, IDs, and financial documents.
No upload wait
Because nothing uploads, processing starts the instant you click. For typical files (under 50 MB) the whole job finishes in seconds — no progress bar, no queueing behind other users.
No daily quota
Free without limits, including no "3 conversions per day" cap that competing services impose. Run as many merge pdf jobs as you need.
No watermark
Your output is clean — no Convertify branding, no metadata stamp. Same as if you'd run a paid desktop app.

Frequently asked questions
Is there really no file size limit?⌄
Correct. Because merging runs in your browser instead of on a server, there is no upload cap — large files and many pages are handled on your own device.
How many PDFs can I merge at once?⌄
There is no fixed limit. You can add dozens of files in one session; the only practical constraint is your device's available memory.
Do I need to register or pay?⌄
No. There is no sign-up, no email required, and no payment — merging is free and unlimited.
Why do other free mergers limit file size?⌄
Most upload your files to a server, which costs them bandwidth, so they cap size or add daily limits. Convertify avoids this by processing locally.
Will big merged files keep their quality?⌄
Yes. Pages are copied exactly, so text stays selectable and images keep full resolution regardless of the total size.
