How to use the Image Resizer

Select or drop an image file. Enter your desired width or height in pixels, or select a preset such as Full HD (1920×1080) or Instagram Square (1080×1080). Keep Maintain Aspect Ratio checked to avoid image distortion. Click Resize Image to generate and download the resized file.

Aspect ratio lock

When aspect ratio lock is enabled, updating either width or height automatically recalculates the other dimension proportionally based on the original image’s dimensions.

Privacy notice

Image resampling is computed directly in your browser using high-quality bicubic canvas interpolation. No file is sent over the network.

Frequently asked questions

What happens if I enlarge an image?

Enlarging an image beyond its natural dimensions scales existing pixels, which can cause softening. For best results, downscale high-resolution originals.

Which presets are available?

Presets include 1920×1080 (Full HD / Landscape), 1280×720 (HD / 16:9), 1080×1080 (Square / Social), and 1080×1350 (Portrait / 4:5).
