PDFCharger: Free Online PDF Tools

I built PDFCharger because I kept hitting the same wall: you need to compress a contract or redact something sensitive, and every tool you find wants you to upload the file to

their servers first. For tax documents, NDAs, medical records — that always felt wrong to me.

So I spent several months building something different. Every tool runs entirely in your browser using WebAssembly. The file never leaves your device. There's no account, no file

size cap, no ads, and no "free tier with a catch." It ended up growing to 130+ tools — merge, split, compress, OCR, redact, sign, convert Word/Excel/PowerPoint, and a lot more.

The feedback that would help me most right now:

- Which tools feel broken or slow on your machine/browser?

- Is there a tool you expected to find that's missing?

- Does the privacy angle actually change whether you'd use it — or is that just marketing noise to you?

- Any friction in the first 30 seconds — confusing UI, unclear what to do?

Genuinely grateful for any of that. Harsh is fine.
