Frequently Asked Questions
Can I resize by percentage instead of pixels?
Yes. Switch to percentage mode to scale your image to 50%, 75%, 200%, or any custom percentage of the original size.
Will the image quality change when resizing?
Reducing image dimensions slightly reduces file size. Enlarging an image beyond its original dimensions may reduce sharpness (upscaling). For best results, resize down rather than up.
What image formats are supported?
JPG, PNG, WebP, and GIF formats are all supported. The output is saved in the same format as the input.
Are my images kept private?
Yes. All resizing happens locally in your browser. Your images are never uploaded to any server.
