Frequently asked questions

How to resize an image by a scale factor?
Select your file and enter a scale factor — values above 1 enlarge the image, values below 1 shrink it.
How does Scale by Factor work?
It multiplies the image width and height by a specified factor, increasing or decreasing the image size proportionally.
Does scaling up reduce image quality?
Yes — upscaling interpolates pixels and can introduce softness. Downscaling generally preserves sharpness better.
What file formats can I export?
You can export as PNG, JPEG, WebP, TIFF, BMP, or HEIC.
Is this tool free to use?
Yes — completely free, no account needed. Your images are processed entirely in your browser and never uploaded to a server. Downloads have no watermarks.
