Frequently Asked Questions
Will compression reduce image quality?
At 80-90% quality, the difference is nearly invisible to the human eye while file size drops dramatically. Use the side-by-side preview to find your sweet spot.
Is there a file size limit?
The web version handles images up to ~50MB efficiently. For batch processing of larger files, the desktop app offers better performance.
