Set your exact width and height or start from a common size preset. Preview the result, keep or unlock its proportions, and download an appropriately sized image.
When should you use it?
Resizing changes the number of pixels in a file. Enlarging a small image does not automatically restore missing detail. For best results, avoid upscaling beyond the original resolution without a dedicated enhancement workflow.
How the conversion works
Choose target pixel dimensions and a format that suits the destination. Lock aspect ratio to avoid stretching. Canvas-based exports are created locally.

Frequently asked questions
Can I keep the aspect ratio?
Yes. Leave the aspect-ratio lock enabled to maintain the original proportions.
Can I resize multiple files?
Yes. The same output settings can be applied to a batch.
Does resizing improve resolution?
Upscaling increases pixel count but cannot recreate detail that was never present.
