How to merge PDF files online

Select multiple PDF files, arrange them in order, and merge into a single document. FixPilot processes everything in your browser — files never leave your device.

Is there a limit?

You can merge up to 20 PDF files at once, each up to 50MB. Since processing happens locally, larger files may take a few seconds longer.

Can I reorder pages?

Yes — files are merged in the order shown. Remove any file by clicking the X button and re-add in your preferred order.
