Hi HN,I built a collection of 40+ PDF tools using Kimi k2.5 (with about $50 worth of credits) and a lot of “vibe coding”.The site: https://pdfuck.com (almost forgot I owned this domain )What it does:40+ PDF-related toolsCompletely freeNo downloads, everything runs in the browserAll processing is done locally in your browser for better privacyIt’s deployed on Cloudflare, so the running cost is basically close to zero.This started as a small experiment and slowly grew into a fairly complete PDF toolbox. I’d really appreciate feedback on performance, UX, and what tools you think are missing.
