About this tool
The Image Resizer changes an image's dimensions — either to an exact width and height, or by scaling to a percentage of the original — with an option to lock the aspect ratio so the image doesn't stretch or distort. Resizing happens using your browser's built-in Canvas API, entirely on your device, so the image is never uploaded anywhere.
Frequently Asked Questions
Will resizing distort my image?
Only if you turn off 'Lock aspect ratio' and enter a width and height with a different proportion than the original — the image will stretch to fill those exact dimensions. Keep the lock on to scale proportionally with no distortion.
Can I make an image larger, not just smaller?
Yes, though enlarging an image beyond its original size doesn't add real detail — it stretches existing pixels, so the result may look softer or blurrier the more it's enlarged.
Is my image uploaded anywhere?
No — resizing happens entirely in your browser using the Canvas API. The image file never leaves your device.
