Frequently asked questions
Is there a file size or page limit?⌄
You can merge up to 50 files, up to 100 MB each. Everything runs in your browser, so the practical limit depends on your device's memory.
Are my files uploaded to a server?⌄
No. Merging happens entirely in your browser using an on-page engine. Your PDFs never leave your device, which makes this safe for confidential documents.
Can I reorder the pages?⌄
You reorder whole files by dragging them before merging. To reorder or remove individual pages, use our PDF Split tool first, then merge the pieces.
Why did my password-protected PDF fail?⌄
Encrypted PDFs must be unlocked before merging. Remove the password in your PDF viewer (or our upcoming decrypt tool), then try again.
