Nothing leaves your PC
Files are processed locally. No upload, no clipboard, no network request.
Online compressors make you upload private files to a server. Compressy runs on your PC — your images never hit the network. JPG, PNG, WebP, AVIF, all local.
Every upload is a copy of your image in someone else's hands. Compress without the network — nothing leaves your disk.
Files are processed locally. No upload, no clipboard, no network request.

Keep the original or convert to WebP/AVIF for smaller files — all local.
No format requires uploading — every conversion stays on your disk.
No upload — just compress and save.
