What is the Maximum image dimensions supported in desktop Chrome?
According to one site I came across, maximum image size in Chrome 4 to 26 and Opera 8 was 8192x8192. Granted that's rather outdated as I'm currently running Chrome 75.
IE 5.5 to 10, FF 19, Opera 9-12 supported (Chrome wasn't specified) will support 16384x16384, which I was able to view a PNG of that size. I attempted 32768x32768 and larger, but it wouldn't display. Browser didn't crash, but all I got was a little white box outline in the center of the page.
I can attempt the larger images from home later to see what happens, as I have substantially more ram on my desktop (if that's a consideration).
After some testing on my personal machine (Chrome v91.0) using ImageMagik to resize an image a bunch of times, I collected the following results - all dimensions are wxh:
- 65000 (ImageMajik maximum supported image dimension) x 8192 (19.5MB) - displayed
- 65000 x 9000 (20.9MB) - not displayed
- 8192 x 65000 (31.9MB) - displayed
- 8292 x 65000 (32.7MB) - not displayed
- 8292 x 8292 (7.1MB) - displayed
- 16384 x 16384 (14.5MB) - displayed
- 23150 x 23150 (23.1MB) - displayed
- 23165 x 23165 (23.7.5MB) - aspect ratio displayed, but image loaded white
- 23170 x 23170 (sqrt(2^29)) (23.8.5MB) - not displayed
So it seems the total size of the image must be less than 2^29 (539MP)
