— frequently asked questions

Is my image uploaded to a server?

No — compression runs entirely in your browser using the Canvas API. Your images stay on your device.

What quality setting should I use for the web?

70–80% quality typically cuts file size by 50–70% with minimal visible quality loss for JPEGs. For PNGs, the quality setting controls how aggressively colour depth is reduced.

Does it support animated GIFs?

GIF compression is limited — the format itself is lossless. The tool can reduce palette size but not apply JPEG-style quality compression to GIFs.

Can I compress a PNG to a JPEG?

Yes — choose JPEG as the output format for PNG inputs to convert and compress in one step. Note that JPEGs do not support transparency.

Is this free?

Yes — free with no sign-in.
