Free PDF tools: merge, split, compress, unlock, convert images to PDF, protect with password, rotate and sign — plus PDF to Markdown and Markdown to PDF conversion. All in your browser, no upload.
PDFs are where documents go to be final — signed, archived, submitted. These 19 tools cover the whole document lifecycle: merge and split, compress for email limits, protect with real encryption, unlock what you own, sign, rotate, watermark, number pages and repair damaged files — plus the Markdown bridge in both directions.
The differentiator is architecture: every operation runs locally in your browser. Contracts, medical records and financial statements never touch a server — read our compression guide to see realistic size-reduction numbers by document type.
