Frequently asked questions
What image formats are supported?
Any format your browser can read: JPG, PNG, WebP, GIF, BMP, and more. Output can be JPG or PNG.
Does resizing reduce quality?
Shrinking generally looks fine. Enlarging a small image will make it blurry — there is no magic way to add detail that was not there.
Can I resize multiple images at once?
Currently one image at a time. For batch resizing, process each image individually.
What does 'lock aspect ratio' mean?
When locked, changing width automatically adjusts height (and vice versa) to prevent stretching or squishing.
Is my image uploaded anywhere?
No. Resizing happens entirely in your browser using canvas. Your image never leaves your device.
