FAQ
Does resizing reduce image quality?
Enlarging images can reduce quality. Reducing size generally looks great. Our tool uses high-quality interpolation for the best results.
Can I resize without changing the aspect ratio?
Yes. The 'Lock aspect ratio' option is enabled by default, so the height adjusts automatically when you change the width.
What's the maximum image size?
There's no file size limit since everything runs in your browser. Very large images may be slower on older devices.
Can I resize to a percentage?
Yes. Use the percentage presets (50%, 75%, 150%, 200%) or enter custom dimensions.
Are my images uploaded to a server?
No. All processing happens locally in your browser. Your images never leave your device.
