⚡Quick Image Compressor
Compress and convert images privately, without uploading.
Why PixNimbus
Shipping the right image size is tedious: export a dozen variants, upload them, wire up srcset. PixNimbus stores one master and generates every variant on demand from the URL — width, quality, and format as query parameters, cached at the edge.
Two ways in: a free in-browser compressor for a quick one-off, and a hosted image CDN for images you serve repeatedly — upload the master once, then request /cdn/<id>?w=800&format=webp anywhere it is needed.
