How to compress images safely

Reduce image size while keeping quality, privacy and the final use in mind.

Practical steps

Choose JPEG, PNG or WebP, set a quality appropriate to the destination, and optionally cap the dimensions. JPEG quality around 80% is often a practical starting point for photographs. PNG works best for sharp graphics and transparency. Always compare the downloaded result with the original.

Privacy and safety

Your selected files stay on your device. Keep backups, work only with files you are authorized to use, and verify every result.
