Questions and answers
How do I compress an image to 100 KB?
Choose the target size mode, enter 100 KB and add your image. The tool searches for the highest quality that stays under the limit, and reduces dimensions only if it has to.
Is the compression lossless?
PNG optimization can be fully lossless. JPG and WebP are lossy, but the default settings are visually very close to the original.
Do my images leave my device?
No. Compression runs in WebAssembly inside your browser tab.
