Frequently Asked Questions
Will resizing reduce image quality?
Enlarging an image beyond its original size may reduce sharpness. Shrinking always maintains quality. Use the quality slider to control output size.
How do I maintain aspect ratio?
Enter only width OR only height — the other dimension is calculated automatically to maintain the original aspect ratio.
Is my image uploaded to a server?
No. Everything happens in your browser using the Canvas API. Your images never leave your device.
