About

I run Codeniverse, a small software studio in Bangkok building AI agents, automation and custom systems for clients. LightUtils is the thing I build on the side. It is 37 file tools (PDF, image, video, CSV) that run entirely in your browser. Not "we delete your files after two hours" but a Content Security Policy that forbids the page from making any network request at all. You can verify it in DevTools in ten seconds. I built it because the people who most need these tools, accountants and HR teams handling payroll files, are the ones who are not allowed to upload anything. It also handles Thai properly, which nothing else in this category does.

LightUtils - 36 file tools that physically cannot upload your files

Every other free PDF tool uploads your file and promises to delete it later. LightUtils cannot upload it. The site ships a Content Security Policy with connect-src 'none', so the browser itself forbids this page from making any network request. Verify it in DevTools in ten seconds. 36 tools for PDF, image, video, audio and CSV. No account, no watermark, no daily limit, no size cap, because there is no server cost per file. Full English and Thai.
