How to use resize image
Select an image to see its current dimensions.
Enter a width/height or percentage, or pick a platform preset (each shows its exact pixels).
Choose fit behaviour: contain, cover (center-crop), or stretch.
Preview the resulting dimensions, then export.

- Presets for common social and document sizes, labelled with exact dimensions
- High-quality multi-step downscaling for sharp results
- Upscale warning before enlarging beyond the source resolution
How the result is verified
The exported image is re-decoded and its pixel dimensions are compared to your requested dimensions before download is offered.
Frequently asked questions
Will resizing distort my image?
Only if you explicitly choose Stretch. Contain scales the whole image inside your target box and Cover center-crops it to fill exactly — both preserve aspect ratio.
Is my file uploaded to a server?
No. The file is opened with your browser's File API and processed by code running in your tab. You can confirm this yourself: open your browser's developer tools, watch the Network panel, and process a file — no request carries your file's bytes. See our How it works page for a step-by-step verification guide.
