Combine PDFs. Stay local.
Private by design — nothing leaves this device.
Combine multiple PDF files into one local merge. Reorder files or pages, free of charge — nothing is uploaded to process your documents.
No. Merging runs in your browser with pdf-lib. Bento Tools does not upload your PDFs for the merge.
Yes. Add several PDFs, drag to reorder, and download one combined file. Advanced mode also lets you arrange or remove individual pages.
Encrypted or passworded PDFs are not supported yet. You’ll get a clear error so you know why a file could not be added.
Practical limits come from your device memory, not a cloud quota. Very large batches may be slower on phones.
