Frequently Asked Questions
Will resizing reduce image quality?
Enlarging an image beyond its original size can look soft, but downscaling uses high-quality smoothing to keep results crisp.
Are my images uploaded anywhere?
No. Resizing happens entirely in your browser using the Canvas API. Nothing is uploaded.
Which formats are supported?
Any image your browser can open — JPG, PNG, WebP, GIF and more. The output keeps the original format where possible.
