Techsinghe Smart Tools
67 free PDF & AI tools that run 100% in your browser
Unlike most "free" PDF tools, nothing here ever touches a server. All 67 PDF/image tools plus 45 AI tools run 100% client-side in your browser using pdf-lib, pdf.js, and JSZip — your file never leaves your device. No account needed for the core toolkit, no watermarks, no daily caps, works offline once loaded. Built solo, refined over time. Would love your feedback on what's missing!
Hey Product Hunt 👋
Maker here. The idea for this started from a really simple annoyance: I needed to merge a couple of PDFs one day, searched for a free tool, picked the first result, uploaded my file... and only afterward started wondering where that file actually went, who could see it, and how long it would sit on their server. That's not a great feeling when the file has personal or financial info in it.
So I started building tools that do the opposite — process everything locally in the browser instead of uploading anything. Turned out to be a fun (and occasionally painful) technical challenge, since browsers weren't originally built for this kind of file processing. Libraries like pdf-lib, pdf.js, and JSZip made it possible to do real PDF manipulation — merging, splitting, compressing, watermarking — entirely client-side.
One tool turned into a few, then a few turned into 67 PDF/image/office tools, and more recently I added a set of AI tools (writing, code, image generation, etc.) for people who want quick AI help without stacking five different subscriptions.
It's been a solo build, done in whatever hours I could find around everything else. Nothing about it is venture-funded or team-built — just something I kept adding to because I use it myself constantly and kept wanting one more tool.
Would genuinely love to hear what you think — what's missing, what feels clunky, or anything you'd expect from a toolkit like this that isn't here yet. I'll be around all day replying to comments. Thanks for taking a look! 🙏
