Roblox Thumbnail resizer — exact 1920×1080

A YouTube thumbnail is 1280×720 pixels (16:9). YouTube requires at least 640 pixels wide and files under 2 MB — JPG, PNG, or WEBP. Pick the 1280×720 preset above, enable the 2 MB optimizer, and download.

A YouTube banner is 2560×1440 pixels, but only the center 1546×423 shows on every device. TVs display the full image while phones crop the sides, so keep logos and text in the middle. The banner preset exports exactly 2560×1440.

The Roblox thumbnail size is 1920×1080 pixels (16:9), minimum 768×432. Game icons are separate at 512×512 pixels. Export PNG or JPG and keep text minimal for small displays.

An Instagram story is 1080×1920 pixels — full 9:16 vertical, the same canvas as Reels covers. Keep faces and captions centered because the reply bar and username cover the top and bottom.

A Facebook event cover photo is 1920×1005 pixels. Keep the bottom-left corner clean because the event title overlays it in feed previews, and export JPG or PNG.

A Facebook cover photo is 851×315 pixels. It displays at 820×312 on desktop and 640×360 on mobile, with your profile picture overlapping the bottom-left — so design around a centered safe zone.

A LinkedIn cover photo is 1584×396 pixels for personal profiles (company pages use 1128×191). Keep the bottom-left empty since your headshot covers it, and place your headline value center-right.

The official YouTube thumbnail size is 1280×720 — but 1920×1080 also works because both are 16:9 and YouTube downscales it cleanly. Stick with 1280×720 to stay comfortably under the 2 MB limit.
