About this tool
What this tool does
Changes an image's width and height. The aspect ratio is kept by default to avoid stretching — can be turned off. The output format matches the input format.
How it works
Upload the image, enter width/height, download the resized image.
Privacy
This operation runs directly in your browser. Your file never leaves your device.
Limitations
1 image per operation, JPEG/PNG/WebP only (no HEIC).
FAQ
