ConvertFast
Hi HN, I built ConvertFast, a desktop tool for file conversion and utilities that works entirely offline. The motivation came from being frustrated with online converters — they upload files to unknown servers, have unclear privacy policies, impose file size limits, and are slow when handling multiple files. I wanted something private, fast, and unlimited. What it does: Converts files locally, no uploads or internet required Supports 2,500+ formats (PDFs, images, audio, video, etc.) Batch processing: convert dozens or hundreds of files at once PDF toolkit: merge, split, compress, extract…

What it does
I made ConvertFast because online converters are slow, limited, and risky. It works offline, supports 2,500+ formats, and includes premium PDF tools plus audio/video utilities. Fast, private, unlimited.
Convert, compress, edit, OCR, enhance, and organize files locally with ConvertFast, a private desktop workspace with 69 dedicated tools.
Convert, compress, edit, protect, and organize files with 2,388 conversion paths across 134 formats , all processed locally. If you have ever needed to convert a file quickly, you have probably encountered more than one of these problems. Every conversion becomes a gamble with your data, your time, and the quality of your files. From everyday office files to camera RAW and professional media formats. Different work. The same private foundation. Choose your role to see how ConvertFast turns unfinished files into ready-to-use results. Turn notes, scans, screenshots, and presentations into the exact file your class or email requires, without an upload queue. Private by design. Do not upload…from convertfast.co

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
