Frequently Asked Questions
What's the maximum size I can resize to?
There's no strict maximum, but very large dimensions (above 8000 px) may be slow on mobile devices.
How do I keep the original proportions?
Enable the 'Lock aspect ratio' toggle. Changing width will automatically update height and vice versa.
Will resizing reduce quality?
Downscaling is lossless in terms of content; upscaling may look soft. For AI-powered upscaling, use the AI Upscaler tool.
Can I resize to percentage?
Yes — switch the unit toggle from 'px' to '%' and enter a percentage like 50 to halve the dimensions.
