Frequently Asked Questions

Everything you need to know about Image Compressor (WebP/AVIF)

Will the output always be smaller?

No. Size depends on the source image, dimensions, quality and output format. The tool reports the actual size change, including increases.

Which output formats work?

JPEG, PNG and WebP depend on browser encoding support. AVIF export only works if the browser supports Canvas AVIF encoding; otherwise the tool reports an error. Display support alone does not mean export is supported.

What happens to transparency and animation?

JPEG uses a white background for transparent areas. Animated images become still images. PNG ignores the lossy quality slider. Review every output before use.

Are images uploaded?

No. Image conversion runs locally in your browser. Up to 20 files are processed per batch; failed files are listed separately.
