Frequently Asked Questions
Is resizing free and unlimited?
Yes. Process as many images as you like with no signup or watermarks.
Are my files uploaded?
No. Canvas resizing runs entirely on your machine.
What does “fit inside width × height” mean?
With aspect ratio on, each image scales uniformly so it fits within the box without cropping or stretching.
Why JPEG output?
JPEG keeps file sizes reasonable after resizing. Your download names end in .jpg.
Very large images?
Extreme dimensions may hit browser memory limits. If something fails, try a smaller target size.
