Frequently Asked Questions
What quality setting keeps compression invisible?
Generally 75% or higher produces no visible quality loss at normal viewing sizes while still reducing file size meaningfully.
Is my image uploaded to a server?
No — compression happens entirely in your browser using the Canvas API.
