How it works
This tool uses your browser's built-in Canvas API to decode the image, then re-encodes it to WebP or JPEG using canvas.toBlob(). Quality is controlled by the slider — higher values produce larger files with finer detail; lower values produce smaller files with more compression artifacts.
WebP is supported in every modern browser and reliably delivers 25–35% smaller files than JPEG at equivalent quality.
Want this automated for your WordPress site?
