Encrypted PDFs are not supported in this version. If a file opens with a password, please unlock it in a desktop tool first. Large or image-heavy files use more memory — work in smaller batches if you experience slowdowns.

FAQ

About merging PDFs

Are my PDFs uploaded?

No. Your selected files are read and processed in your browser. Their contents are not transmitted to our servers.

Do you keep my files after I close the tab?

No. Files live in memory only. Closing or reloading the tab discards them. Use the download button to save the merged result.

What about encrypted PDFs?

Encrypted PDFs are rejected with a clear reason. Open them in a desktop tool to remove the password, then add them here.

Is there a page-count limit?

No fixed limit — your device's memory sets the practical limit. For very large or image-heavy documents, working in smaller batches keeps things stable.
