Smolr

Make images Smolr - Compress images to modern formats

Smolr launched on January 27, 2026.

What it does

Smolr is a free, open-source macOS app that compresses and converts images to modern formats like WebP, AVIF, and JPEG XL. - Compress images with quality control - Convert to WebP, AVIF, JPEG XL from PNG, JPEG, GIF, WebP, AVIF, JPEG XL - Batch process multiple files at once - Quality slider for precise control (50-100%) - Strips metadata to reduce file size - 100% local processing - No subscriptions, no ads, no tracking - Open source - Simple drag & drop interface

Free, open-source macOS app to compress and convert images. Supports modern formats like WebP, AVIF, and JPEG XL. All processing happens locally on your Mac. No upload required.

For some things, smaller is better... or so I've been told... Smolr is a small tool that let you convert and optimize your image files to make them smaller and more usable. Nothing more. Convert images to your preferred format and optimise their size at the same time. Choose between lossless conversion or controlled quality reduction with optimization profiles. Convert multiple image files at once using the same output settings. Set default settings, add a custom suffix and select an optimization profile to match your needs. Fully open source , no required payment. Support is optional. Smolr is free but support goes a long way keeping small projects maintained and growing. If you have any…from smolr.io

    I 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.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

    Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
