Frequently asked questions
Is my image uploaded anywhere?+
No. Your image is decoded and resized entirely in your browser using the Canvas API. Nothing is uploaded to a server.
Will resizing reduce the quality of my image?+
Enlarging beyond the original dimensions can soften details. Shrinking is generally lossless visually — you'll get a sharp, smaller image.
What file formats are supported?+
Any image format your browser can decode, including JPG, PNG, WebP, and GIF. The output keeps the original JPG or PNG format.
Why should I lock the aspect ratio?+
Locking the ratio keeps your image proportional so people and objects don't appear stretched or squashed. Turn it off only when you need an exact non-proportional size.
