TinyFast▲319I am a developer. I have been building stuff for the last 13 years. One common challenge in all my projects is compressing assets to make them as small as possible. I used to end up using online compressors, but this has a lot of privacy concerns. So, I finally set down for couple of weeks and built this simple app. I can just drag and drop assets in it and it shrinks them. It currently supports around 25 file types. I built a lot of iOS apps but this is the first time building a macOS app, so any feedback is welcome.

I built heicconvert.it — a fast, private, and completely browser-based HEIC/HEIF image converter that supports output conversion to JPEG, PNG, WebP, or even AVIF. Why I made it: - Photos from iPhones often come in HEIC format, which isn’t broadly supported everywhere. - Existing tools tend to require uploads, compromise privacy, or feel clunky. - I wanted a zero-friction, client-side tool where conversion happens instantly, in your browser, without ever touching a server. Try it - https://www.heicconvert.it - No signup, no tracking, and no data is sent to anyone. What’s…

Hey HN, I built a small web tool to convert JPG, PNG, and WebP images into AVIF — no sign-up, no compression limits, no backend storage. It started as a weekend side project after I got frustrated with most AVIF converters being either too slow, paywalled, or without preview/download flexibility. Key features: - Drag & drop or multi-file upload - AVIF output with 100% quality (or configurable in backend) - Live image preview + original vs AVIF size savings - Individual or ZIP download - Built with Laravel, Tailwind, and vanilla JS - Images auto-delete after 2 hours No ads, no analytics.…

Smallimg▲7Hi HN, I built a free image compression tool called Smallimg.cc that runs entirely in the browser. The main motivation was privacy. I was never comfortable uploading potentially sensitive images to a third-party server just for compression. This tool solves that by using JavaScript and WebAssembly to perform all the processing on the client-side. Your files are never transferred over the network. Key features: Total Privacy: Your images never leave your computer. Incredible Speed: No upload/download time, just instant processing. Full Control: You can adjust quality, resize, and convert…
