HOW IT WORKS
Resize without sending the image away
The browser decodes your image, redraws it at the dimensions you choose, then creates the downloadable result locally.
Resize
Set exact dimensions or scale the image from 10% to 300%.
Save
Choose the output format and download the resized image.
ASPECT RATIO
Keep proportions by default
The width and height stay linked unless you unlock them. This prevents accidental stretching while still letting you choose custom dimensions when needed.
IMAGE QUALITY
Upscaling cannot invent real detail
Making an image larger increases its pixel dimensions, but it cannot restore detail that was not present in the original image. JPG and WebP quality can also affect the output file size.
