Frequently asked questions
How much smaller can my image get?+
Photos typically shrink 60–90% with little visible quality loss. Drag the quality slider and watch the live file-size readout to find your sweet spot.
Will compressing lose quality?+
JPG and WebP use lossy compression, so very low settings can soften detail. At 70–85% quality the difference is usually invisible. PNG stays lossless.
Is it really private?+
Yes — compression runs in your browser with the Canvas API. Your image is never uploaded, and metadata is stripped in the process.
