Hey Product Hunt! I built brevtool because I kept having the same experience with online tools: 1. Need to merge two PDF contracts 2. Upload them to a 'free' tool 3. Hit a paywall after 2 files 4. Realize that tool now has copies of my contracts on their server That last part bothered me the most. So I built something where it's architecturally impossible for your files to leave your device. Brevtool processes everything directly in your browser using WebAssembly. There is no upload step — because there is no server processing. What you get — completely free, no signup: • 78 tools across 9 categories • PDF — merge, split, compress, convert to/from Word • Image — compress, resize, convert formats, remove background • Video — full timeline editor • Developer — JSON formatter, JWT decoder, regex tester, 15+ more • Text tools, calculators, data converters, generators The catch? Non-intrusive ads. That's it. No premium tier. No watermarks. No daily limits. I'd love your feedback — especially on the video editor. It supports trimming, filters, text overlays, transitions, speed control, and crop. All running client-side. Verify for yourself: open DevTools → Network tab while using any tool. Zero file uploads. brevtool.com

I built BrevTool because I kept running into the exact same frustrating loop:

  1. Need to quickly merge two sensitive PDF contracts.

  2. Find a "free" tool on Google.

  3. Hit a $19.99/mo paywall after the second file.

  4. Realize my private contracts now live on a random server forever.

That last part bothered me the most. We are constantly trading our digital privacy for basic utility. So, I built a platform where it is architecturally impossible for your files to leave your device.

BrevTool is a suite of 78+ everyday tools powered entirely by WebAssembly. Because everything runs locally in your browser, there is zero server processing. No uploads. No waiting. No data harvesting.

🧰 What you get (100% Free, No Sign-ups):

  • 📄 PDF: Merge, split, compress, Word conversions.

  • 🎬 Video: A full timeline editor (trim, crop, transitions, speed, filters).

  • 🖼️ Image: Compress, resize, format convert, background removal.

  • 👨‍💻 Developer: JSON formatter, JWT decoder, regex tester, +15 more.

  • 🔀 Plus: Text tools, calculators, data converters, and generators.

The Catch? Just non-intrusive ads. That’s it. There are no premium tiers, no watermarks, and no hidden file-size limits.

My Ask For You: I’d love your feedback—specifically on the Video Editor. Building a full, responsive video editor that runs entirely client-side was a massive challenge. Let me know how it handles your files!

🕵️‍♂️ The DevTools Challenge: Don't trust my privacy claims? I don't blame you. Open your browser's DevTools → Network tab while using any tool on the site. You will see exactly zero file uploads.
