Frequently Asked Questions
Can I maintain the original image aspect ratio?
Yes, the aspect ratio lock is enabled by default so entering a new width automatically scales the height proportionally.
Will resizing reduce the image quality?
Downscaling retains sharp quality. Upscaling beyond original dimensions is handled with smooth bicubic interpolation.
Can I export in a different format?
Yes! You can choose to export your resized image as JPG, PNG, or modern WebP format.
Are my images stored on your servers?
No. Resizing is performed 100% inside your browser memory.
