Every app here works on your own machine. No account, no subscription. You buy it once and it is yours.
An audio editor for game audio. Three lanes, crossfades, effects, and loop points that travel inside the file, so RPG Maker, Unity, and friends play them the way you set them.
Compress PDFs and images to the size you need. Drag a target, see the result, keep the text sharp.
The same idea for video. Pick a preset and get a much smaller file that still looks great, without learning a codec. Works on whole batches, and a video never comes out larger than it went in.
A capture log for notes. Plain Markdown files in a folder you choose, so your notes outlive the app.
