Frequently Asked Questions

Compression always involves some trade-off. This tool uses the highest possible JPEG quality that still meets your target size. The quality slider lets you control the balance — set it higher to prioritise quality, lower to prioritise size.

The tool accepts images up to 50 MB. Very large images may take a few seconds to process depending on your device.

Switch to the Resize tab, choose Centimetres (cm) mode, enter your desired width and height in cm, choose the DPI (300 for print, 72–96 for screen), and click Resize Image.

No. This tool runs entirely in your browser using JavaScript and the HTML5 Canvas API. Your images are never sent to any server. They stay on your device at all times.
