Common questions

Can I resize to exact pixel dimensions?
Yes, set any width and height. Toggle aspect ratio lock to prevent stretching.
Does resizing reduce file size?
Yes. Reducing dimensions directly reduces pixel count and file size proportionally.
What is the maximum image size?
No hard limits. Very large files (50MB+) may take longer to process.
