Frequently asked questions
Can I resize by percentage instead of exact pixels?+
Yes. You can scale by percentage (e.g. 50% to halve dimensions) or enter exact width and height in pixels. Both options are available.
Will resizing reduce image quality?+
Downscaling rarely causes visible quality loss. Upscaling can introduce softness since new pixels must be interpolated. The tool uses bicubic resampling for the best results.
Can I maintain the aspect ratio?+
Yes. When aspect ratio lock is enabled, changing one dimension automatically adjusts the other to prevent stretching or squishing.
Can I resize multiple images at once?+
Yes. Batch resizing is supported. All images are resized to the same target dimensions or percentage.
Is this processed on a server?+
No. Resizing happens entirely in your browser using canvas APIs. Your files never leave your device.
