Frequently asked questions

How do I merge PDF files into one?

Choose two or more PDFs — and photos too, if you like — put them in the order you want, and select Merge PDF. PDF pages are copied without re-rendering, so text stays sharp and searchable; images become new pages.

How do I merge PDFs without uploading them?

Use this tool: the files are read and merged by your browser on your device. Nothing is sent to a server, which you can confirm by disconnecting from the internet after the page loads.

Is there a limit on the number of files?

There is no fixed file count. The combined size is limited by your device's memory; around 100 MB total works well on most computers.

Does merging reduce quality?

No. Pages are copied directly, so text, vector graphics and images remain exactly as they were.

Can I merge PDFs and photos together?

Yes. Add JPG, PNG or WebP images alongside your PDFs. Each image becomes a page (fitted to A4, Letter or its own size) and PDF pages are copied unchanged, so text in the PDFs stays selectable.

Do I need to create an account?

No. Every tool works without sign-up or login.

Is it safe for confidential documents?

Files are processed locally in your browser and never uploaded. Close the tab or select Clear to release them from memory.
