100% Client-Side Privacy
Zero data is sent to external servers. Your image dimensions, canvas properties, and output files stay inside your local browser memory.
Adaptive Fallback Downscaling
If compression alone does not fit the target size, we automatically downscale the dimensions dynamically to meet the size limit.
