Frequently asked questions
Are my images uploaded anywhere?
No. Resizing happens entirely in your browser using the canvas API, so the file never leaves your device.
What does “Lock aspect ratio” do?
It keeps the original proportions: change the width and the height follows automatically, so the image never looks stretched.
Can I enlarge an image?
Yes, you can enter dimensions larger than the original, but enlarging can't add detail that isn't in the source file.
Which formats are supported?
JPG/JPEG, PNG, and WebP, both as input and as output. Choose WebP for the smallest files on the web.
