Frequently Asked Questions
Which image formats are supported?
You can upload PNG, JPEG, and WebP images. The tool converts between all three formats using the browser Canvas API.
How does the quality slider work?
The quality slider (1-100) controls compression for JPEG and WebP output. Lower values produce smaller files with more compression artifacts. PNG output is always lossless, so the slider does not apply.
Is my image data safe?
Yes, all conversion happens entirely in your browser using the Canvas API. No image data is uploaded to any server.
Which image format offers the best compression for web?
WebP generally offers the best balance of quality and file size for web use, producing files 25-35% smaller than JPEG at equivalent quality. AVIF achieves even better compression but has less browser support. Use JPEG for photographs when broad compatibility is needed, and PNG when you need transparency or lossless quality.
