Questions and Answers
WebP is the modern web standard, offering up to 30% smaller files than JPG with the same visual quality. It is supported in every current browser (Chrome, Firefox, Safari, Edge).
To compress an image without perceptible quality loss, keep the quality slider above 70%. In that range the visual difference is imperceptible in most photos. For images with text, graphics, or fine detail, stay above 85% to preserve sharpness.
No. Compression happens directly in your browser, so your images are not uploaded or stored on any server.
There is no hard limit, but since processing uses your browser memory, we recommend images up to 50 MB for a smooth experience. Very large files may slow down depending on your device.
