PDF Tools: Merge, Split, Compress and Watermark

Merge, split, compress, rotate, watermark and unlock PDFs in your browser. Ten tools that run on your device: no upload, no account, nothing installed.

Frequently asked questions

Are my PDFs uploaded anywhere?

Never. All eleven tools (merge, split, compress, rotate, page numbers, watermark, protect, unlock, organize, JPG to PDF, and PDF to Excel or CSV) run locally in your browser with pdf-lib and pdf.js. Files stay on your device.

How do I split a PDF by page range?

Enter ranges like 1-3, 5, 8-10 and download the extracted pages as separate PDFs. Ranges are validated against the document’s page count.

Can I merge PDFs in a custom order?

Add multiple files, reorder them with the up/down controls, and merge into a single document in that exact order.

How does compression avoid quality loss?

Compression is lossless: PDF object streams are re-packed and unused metadata is stripped. Text, images, and vector quality are untouched, with before/after sizes shown.
