Honest limits
Very large images can hit browser memory or canvas size limits. HEIC and WebP support depends on the browser. JPG output cannot preserve transparency.
Questions
Can I keep aspect ratio?
Yes. Keep aspect ratio enabled to update width and height together.
Does resizing upload the image?
No. Canvas resizes the image in this browser tab.
Will resizing reduce file size?
Usually yes when dimensions get smaller, especially for photos.
