## Image Compressor

Shrink JPG, PNG & WebP photos with no visible quality loss.

Your files never leave your device. Compress images, merge PDFs, convert video to GIF, generate Excel formulas, beautify screenshots, and transcribe audio — no uploads, no accounts, no tracking.

Every YuliusBox tool runs on your device using modern browser technology — WebAssembly, the Canvas API, and on-device AI models like Whisper. When you drop a file into a tool, it is processed by your own CPU and GPU; nothing is sent to a server, stored in a database, or logged. That means no queues, no file-size quotas imposed by server costs, and no privacy trade-offs — your tools even keep working offline once the page has loaded.

Files are processed on your device and never sent to a server.

Every tool works instantly. No accounts, no email walls.

All core tools are free to use, with no watermarks.
