Is this tool really free?
Yes. Every tool on this site is free, with no account or sign-up required.
Are my files uploaded to your servers?

In what order are files merged?
In the order shown in the file list. Use the up and down arrows to reorder before merging.
Batch Process applies one operation to many PDF files at once. Add up to 50 PDFs, pick rotate, compress or merge, press Process, and download each result or grab them all as one ZIP. Everything runs in your browser.
The operation you pick applies to all files in the batch. Files that need different operations go in separate runs. Merging is the exception: it combines everything into a single PDF instead of one result per file.
It does not mix operations in one run, and it does not edit page content. Rotation turns all pages, compression shrinks files, and merging joins files. For page level work on one file, use the single file tools.
How many files can I add?
Up to 50 PDFs in one batch.
Do I get one file or many?
One result per file, except merging, which makes a single PDF. Download each result or grab them all as one ZIP.
Are my files uploaded?
No. Everything runs in your browser.
