Show DEV: A Free PDF Editor That Runs Entirely in Your Browser (No Uploads)

Most "free" PDF editors ask you to upload contracts, invoices, and IDs to their servers before you can touch them. I built an alternative I'm comfortable using on my own documents.

ToolsMonk PDF Editor edits PDFs locally in the browser — the file never leaves your device.

What it does

• Edit — add text, images, shapes and annotations directly on pages
• Merge & split — combine documents or extract exactly the pages you need
• Compress — shrink files without the usual quality collapse
• Sign — draw or place signatures on contracts
• OCR — pull text out of scanned documents
• Convert — PDF ↔ Word / Excel / PowerPoint, both directions

Why on-device matters here

A PDF is usually the final version of something sensitive — an offer letter, an NDA, a bank statement. Privacy policies are nice; not uploading the file at all is nicer. Everything above runs client-side. The few tools on ToolsMonk that do use a server (some AI features) are listed openly at toolsmonk.com/where-your-files-are-processed.

Three ways to use it

• 🌐 Web: toolsmonk.com/tool/pdf-editor
• 🖥️ Windows desktop app: same tools as an Electron app, v1.1.24 via GitHub Releases
• 📱 Android app: built with Flutter, on Google Play

No account, no watermark, no "upgrade to export" wall.

If you try it, tell me which PDF task you reach for most — merge and compress are the heavy hitters in my own usage, but I'm curious what yours are.
