Why AI Cannot Replace This Tool
AI chatbots can describe image resizing or tell you the dimensions you need, but they cannot actually resize your image. Pixel-level operations like resampling, interpolation, and format conversion require real computation on actual image data. This tool performs those operations precisely on your device, with zero privacy risk.
Frequently Asked Questions
Is my image uploaded to any server?
No. All image processing happens entirely in your browser using the Canvas API. Your image never leaves your device.
What image formats are supported?
We support JPG, PNG, WebP, GIF, and BMP as input. You can output as JPG, PNG, or WebP.
Will resizing reduce image quality?
Enlarging an image beyond its original size will reduce sharpness. Reducing size typically preserves quality well. Our tool uses high-quality bicubic interpolation for the best results.
What is aspect ratio lock?
When locked, changing the width automatically adjusts the height (and vice versa) to maintain the original proportions. Unlock to set width and height independently.
