Most "free" PDF tools are a privacy nightmare. So I built a serverless one.

Hey Product Hunt community! 👋

I’ve been a long-time user of "free" online file compressors, but I recently went down a rabbit hole of reading Privacy Policies for some of the biggest tools in the space.

It’s alarming how many of them upload your sensitive files (think bank statements, IDs, and contracts) to their servers before processing. Even if they "delete them after an hour," that window of risk is there.

I decided to solve this for myself by building SlimDoc.

The technical challenge: I wanted to see if I could handle heavy lifting like PDF and Office document compression 100% in the browser. No cloud uploads, no server-side processing, just pure client-side magic.

Why I’m sharing this now: We are gearing up for our official launch [https://www.producthunt.com/products/slimdoc], and I’m curious about how this community handles document security:

  1. Do you blindly trust online tools for sensitive files, or do you stick to heavy desktop apps like Acrobat?

  2. If you’re a dev: What are your thoughts on the "Local-First" movement for utility tools?

  3. What’s one file type you always struggle to get under that "email size limit"?

I’d love to hear your thoughts and get some early feedback on the browser-based approach!
