Generic image compressors are tuned for photographs. Memes are not photographs — they are screenshots, flat colour fields, and impact-font text, and they react very differently to compression. A screenshot meme saved at default quality compresses 80-90% with almost no visible change, because the image carries so little real detail. The failure mode is specific: push too far and the thin white outline around caption text breaks up first, long before the background shows any damage. That is why a meme compressor needs a quality check step, not just a size target.\n\nCompress on the quality slider, look at one meme at 100%, then batch the rest with the same setting. Skwish runs entirely in the browser, so nothing is uploaded and you can process an unreleased draft without it leaving your machine.
