Frequently asked questions

In what order will my PDFs merge?
They merge in the order you add them. Drop the first PDF, then the second, and so on. To reorder a batch, remove a file and add it back in the right position.
Will bookmarks, links, and form fields survive?
Internal page references, hyperlinks, and basic form fields are preserved by the underlying PDF library. Some advanced interactive features (signed forms, encrypted PDFs, complex JavaScript actions) may not carry through cleanly.
Is there a file-size limit?
No fixed limit on our end. Everything runs in your browser, so the practical limit is your device's memory — typically several hundred megabytes total without issues.
Can I merge password-protected PDFs?
Not yet. You'll need to remove the password first. An Unlock PDF tool is on the roadmap.
Are my files really not uploaded?
Correct. Every conversion in this tool runs in your browser using JavaScript and the local file APIs. There is no server-side processing, no file upload, no temporary storage, and no log of what you converted. You can verify this by opening your browser's network tab while converting — the only traffic is loading the page itself.
Do I need an account or to install anything?
No. Open the page, drop your file, download the result. No signup, no email, no extension, no app.
Is there a file-size limit?
Not from us. The practical limit is your device's memory — browser tabs typically handle files in the hundreds of megabytes range without issues. Very large files may take longer to process on phones than on laptops.
