Frequently asked questions
How do I choose the order of the merged PDF?
Reorder the files in the list before merging. The pages are combined from the top file to the bottom one, and each file keeps its own page order.
Is there a limit on how many PDFs I can merge?
There is no fixed limit. The practical limit is your device's memory, so very large PDFs may need to be merged in smaller batches.
Are my files uploaded anywhere?
No. Merge PDF runs entirely in your browser. Your files are processed on your device and are never sent to a server.
Is there a file size limit?
No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.
Is Merge PDF really free?
Yes. There's no account and no watermark. A short optional ad, or a 20-second wait, unlocks each download. That's how we keep it free.
Does it work offline?
Once the page has loaded, processing happens locally, so it keeps working even if your connection drops.
