About Resize Image

Resize Image scales an image to exact pixel dimensions or a percentage of its original size, with optional aspect-ratio lock. It's the right tool for prepping product photos for a webshop, fitting profile pictures into a required size, or downscaling huge screenshots for documentation.

FAQ

Can I lock the aspect ratio?
Yes - toggle the lock so changing one dimension automatically updates the other in proportion.
Can I resize by percentage instead of pixels?
Yes, switch the unit to ‘%’ to scale relative to the original (e.g. 50% halves both dimensions).
Is Resize Image free?
Yes. Every tool on docsntools is 100% free with no signup, no watermarks, and no upload limits.
Are my files uploaded to a server?
No. All processing happens entirely in your browser. Your files never leave your device.
Does it work on mobile?
