Frequently asked questions

How do I resize an image without losing quality?
Downscaling (making an image smaller) rarely causes visible quality loss. When upscaling, some blur is unavoidable. For best results, keep the aspect ratio locked.
Can I resize images to a specific width only?
Yes. Lock the aspect ratio, type the width you want, and the height is calculated automatically to prevent distortion.
Are my images uploaded anywhere?
No. Resizing happens locally in your browser via the Canvas API. Your images never leave your device.
Which units can I use?
Dimensions are set in pixels, which is what almost all websites, apps and design tools expect.
What formats are supported?
You can resize JPG, PNG and WebP images. The output keeps the original format.
Is there a cost or limit?
The tool is completely free with no usage limits and no account required.
