01

02
Set size and quality
Choose a bounding box and format. Images are never enlarged. JPEG and WebP use the quality setting; PNG remains lossless and ignores it.
03
Check the measured result
The result shows actual before/after file sizes and output dimensions. Some format changes create larger files, so use the reported sizes rather than assuming a saving.
Know what to expect
Metadata is not retained. Animated files, RAW, HEIC and SVG are not supported; colour-critical work needs a dedicated review.
Source files stay in the current browser page and clear on reload. Save the output before leaving, and retain original files for important work.
