Which image formats are supported?

NovaKit supports JPEG, JPG, PNG, and WebP. You can also cross-convert formats during compression.

Is there a limit on how many images I can compress?

No. Because compression runs on your device rather than our servers, there are no limits, no subscriptions, and no paywalls.
