Years ago I made a small Windows-only image converter. Its last release, v0.4.3, came out in 2019, and then nothing for 7 years. This year I rebuilt it from scratch (in Rust) for Windows, macOS and Linux. It's called Skidbladnir, and it's free and open source. What it does Named for the Norse ship that carried every god aboard and still folded into a pocket. Skidbladnir does the same for your images: every pixel aboard, but a fraction of the size. It turns your JPEG and PNG images into WebP, AVIF, JPEG XL or HEIC, which are typically far smaller than JPEG/PNG at the same visual quality. The screenshot is a real example, a 1.81 MB image in, a 183 KB WebP image out, that is a ~90% reduction in size but almost no perceivable loss in clarity. Some of the biggest features are live before/after preview, the ability to batch whole folders and even include sub-folders, full control over every compression setting for the most consistent results, and of course, no account, no subscription, no limits, no ads, and you images never leave your machine. Be aware that it isn't code-signed so your OS will warn you about installing, but I'm working on that.

And if you're on a Mac: nobody has opened the Mac build on real hardware yet, so please tell me if it even launches.   submitted by   /u/physics515 [link]   [comments]
