Frequently Asked Questions
Is there a file size limit?
No. You can optimize images of any size, though very large files may take longer to process.
Do you upload my files to a server?
No. All optimization happens locally in your browser. Your files remain private.
What quality setting should I choose?
Most users find 80–90 is the sweet spot for reducing file size while keeping excellent image quality.
What’s the difference between lossy and lossless?
