About
ImgKit is a free, privacy-first web application designed to compress, resize, and convert images directly within your browser tab. Unlike traditional image tools, it processes everything locally on your device without uploading files to a server, ensuring your photos never leave your computer or phone.
The platform is built for anyone who needs to quickly optimize photos, remove backgrounds, blur faces, or convert formats like HEIC, JPG, PNG, WebP, and AVIF without creating an account or dealing with watermarks. It operates entirely client-side using WebAssembly and local models.
What sets ImgKit apart is its complete emphasis on privacy and speed. There are no upload waiting times, no storage buckets, no cookies or ad trackers, and the tools even continue to work completely offline when the internet is turned off.

Credit Karma ads model: helpful matching beats banner spam
Life360's aspirational ad model is Credit Karma: match driving-score data to insurance offers, or surface an Uber tap-to-book when the app detects a user just landed at an airport. Their internal bill of rights forbids any ad that interrupts the job-to-be-done. Ads that add genuine contextual value convert better than banner spam and preserve trust with the 87.5% of Life360's user base who are permanently on free.
I would recommend that people move very quickly because right now you can get OpenAI credits dirt cheap, and I don't think it'll be like that forever. They're just doing user acquisition right now on their end.
OpenAI credits are dirt cheap right now — this margin window won't last
AI infrastructure providers are subsidising inference to capture developers — the same playbook every cloud has run. Margins on AI wrappers are temporarily inflated, so the founders moving fastest into the gap capture the most. Building 'when the dust settles' means waiting for 30% margins instead of 90%.
There's a play for whatever you're stuck on.
