Questions

Are my PDFs uploaded?

No. The PDFs are merged by your own browser and never leave your device. Nothing is saved.

Can I make the merged PDF smaller?

Yes. Choose Compress to shrink it for email or WhatsApp, and pick greyscale or black and white for the smallest files.

Does it work with scanned PDFs?

Yes. It detects scanned pages, and Enhance makes faint or grey scans clearer and easier to read.
