Frequently asked questions
Are my images uploaded anywhere?
No. Resizing runs entirely in your browser using the Canvas API. Your images never leave your device, so there are no upload limits and no privacy risk.
Will resizing keep the proportions?
Yes, when 'Lock aspect ratio' is on (the default). Set just the width and the height is computed to match, so images never look stretched. Turn it off to force exact width and height.
Can I enlarge a small image?
You can set dimensions larger than the original, but enlarging can't add detail that isn't there — the result will look softer. For best quality, resize down rather than up.
