Frequently asked questions
Are my images uploaded?
No. Resizing happens entirely in your browser — your image never leaves your device.
What is 'lock aspect ratio'?
When locked, changing the width updates the height automatically (and vice-versa) so your image doesn't look stretched.
Can I make an image larger?
Yes, but enlarging beyond the original size can look soft, since there's no extra detail to add.
Which formats are supported?
JPG, PNG and WebP. PNG transparency is preserved; other formats are saved with a white background as JPG.
