Let’s be honest: there are a million PDF converters. PrivateTools includes the basics, but focuses on unique, micro-niche tools (like Webtoon Croppers or Discord 8MB compressors). The difference? Everything runs 100% locally in your browser via WebAssembly. Zero server uploads, zero tracking, unlimited file sizes, and completely free. Open-source and built for true data privacy.

Hey Product Hunt! 👋 I'm Sikandar, the maker of PrivateTools.
Why I built this: Let’s be honest—there are already a million "PDF to JPG" converters out there. I included those basics because they are essential, but my real mission is building unique, micro-niche tools that solve specific, annoying problems (like our Webtoon Panel Cropper or Discord 8MB Video Compressor).
The problem with all these tools, basic or niche, is that they force you to upload your files to a server. PrivateTools changes that. Everything runs 100% locally in your browser using WebAssembly. Your files literally never leave your device. Because it's local, you also get unlimited file sizes and unlimited usage—no paywalls, no queues.
I’d love your specific feedback on:
What micro-niche tool do you wish existed but can't find?
Which of our current unique tools is most useful for your daily workflow?
How does the performance feel on larger files?
The project is open-source (link in the description), so feel free to check the code! I'm actively researching new ideas, so drop your suggestions below. Thanks for checking it out! 🚀
🚧 Sneak Peek: Tools Currently in Development
Hey everyone! While the current tools are live and working, I'm actively building 3 new micro-niche tools that should be ready soon:
1️⃣ EPUB Checker - Validate and fix EPUB files before sending to Kindle
https://www.privatetools.in/tools/document/epub-checker
2️⃣ CSV & JSON SQL Query Tool - Run SQL queries directly on CSV/JSON files in your browser (powered by DuckDB WebAssembly!)
https://www.privatetools.in/tools/developer/csv-json-sql-query
3️ VCF to CSV/Excel Converter - Convert iPhone/Android contacts to clean CSV/Excel format
🔗 https://www.privatetools.in/tools/data/vcf-to-csv
All of these are still in active development, but I wanted to share them early. The SQL Query tool is probably the most exciting one—it lets you run full SQL (SELECT, JOIN, GROUP BY) on your CSV files without ever uploading them anywhere.
Would love your early feedback: What features would you want in these tools? Any other micro-niche problems you wish I'd solve next?
The goal is to keep building unique, privacy-first tools that run 100% locally. No uploads, no tracking, just useful utilities. 🛠️
