I understand this isn’t a small request. There’s bandwidth issues, overhead, etc. I get it. I also know the file size requirement is in part an incentive to pay for Nitro. Regardless:
Please bump up the max file size for free accounts up to a more reasonable 10 or 12 megabytes. In most cases 8MB is a reasonable amount, but as resolutions of screens have gotten larger, it’s become more of a hassle to share pictures with friends. This isn’t always an issue on desktop, although on occasion even a 1080p screenshot can exceed 8MB. On mobile, however, it’s a near constant issue. I have an iPhone X and 10.5 iPad Pro. Screenshots from those can easily exceed 8MB. It’s annoying having to always immediately crop it by some arbitrary amount just to slide under the number. This will only become more of a problem as phones and computers move beyond 1080p.
