What Is Social Banner Generator?
Social Banner Generator creates correctly sized header and cover images for Twitter/X, Facebook, LinkedIn, YouTube, and other platforms. Each platform has different dimension requirements — this tool handles the sizing so your banners look sharp without getting cropped.
How to Use This Tool
Select your target platform to load the correct dimensions, then customize the design with text, colors, gradients, and layout options. Preview how the banner will appear on the platform, then download the image. The entire process runs in your browser with no uploads or account needed.
Why Use Social Banner Generator?
Social media banners get cropped differently on mobile vs desktop, and every platform has unique aspect ratios. This tool provides platform-specific templates with safe zones marked, so your text and key visuals never get cut off. It’s free and runs client-side for complete privacy. For a detailed walkthrough, see our step-by-step guide.
Frequently Asked Questions
What sizes does the Social Banner Generator support?+
Four: X header at 1500×500 (3:1), LinkedIn personal profile background at 1584×396 (4:1), YouTube banner at 2560×1440 with its 1546×423 safe area, and a Facebook cover at 820×360. Facebook shows covers at 820×312 on computers and 640×360 on phones, so the 820×360 canvas covers both and the tool keeps text inside the 640×312 area they share. LinkedIn company pages use a different size (1128×191) that the tool does not offer.
Why is YouTube channel art 2560×1440 with a safe zone?+
YouTube shows the same upload at different crops: the whole image on TVs and progressively narrower strips on desktops, tablets and phones. Only the central 1546×423 area appears everywhere, so the tool lays out text inside it and outlines it with a dashed line in the preview. The outline is not part of the exported PNG.
How is the PNG exported?+
The live preview is rasterised with html2canvas 1.4.1 and saved as a PNG at the platform's size: 1500×500, 1584×396, 2560×1440 or 820×360, or at twice that with 2x retina export (not offered for YouTube, which is already 2560 wide). We checked all eight combinations for exact dimensions. html2canvas redraws the page itself rather than taking a screenshot, so very unusual CSS can differ slightly from the preview. Copy to Clipboard puts the same PNG on the clipboard.
Do uploaded logos ever leave my browser?+
No. Uploaded logos are read into a browser File API object via FileReader and rendered directly into the preview. Nothing uploads to a server, nothing logs, nothing persists after the tab closes. You can verify with the DevTools Network tab — zero requests leave your browser after the initial page load and the html2canvas CDN fetch at export time. This matters because social banners often include unreleased product logos, prototype brand marks, or client assets under NDA that shouldn't be transmitted to third-party services.
What text length works best on each banner size?+
Short. X, LinkedIn and Facebook banners are wide strips, so a headline of up to about 50 characters stays on one line at the default size and a subhead works best under 100. YouTube's safe area is a wide strip too (1546×423, about 3.7:1), so keep the channel name and a short tagline. Text sizes are set per platform from the banner height (the safe-zone height for YouTube and Facebook), so long text wraps rather than shrinking.
How do I actually upload the banner to each platform?+
For X: Profile → Edit profile → click the header area → Upload photo. For LinkedIn: Profile → camera icon on the banner → Upload photo → crop. For YouTube: Studio → Customization → Branding → Banner image → Upload. For Facebook: Profile → camera icon on the cover → Edit cover photo → Upload photo. Every platform lets you reposition after upload, but if you used the generator's native size, positioning should be centered by default. After uploading, check the result on both desktop and mobile — platforms occasionally re-crop, and what looks right on one device may need a position tweak on the other. The companion guide walks through all four upload flows with screenshots.
Which platforms and banner sizes are supported?+
X header (1500×500), LinkedIn personal profile background (1584×396), YouTube banner (2560×1440, 1546×423 safe area) and Facebook cover (820×360 canvas, 640×312 safe area). YouTube and Facebook show the safe area as a dashed outline and keep text inside it; X and LinkedIn use simple padding.
Why do my banners look cropped on mobile but fine on desktop?+
Platforms crop banners differently by device. Facebook shows 820×312 on computers and 640×360 on phones, YouTube narrows to its central strip on phones, and on X and LinkedIn your profile photo covers part of the banner. Keep key text inside the dashed safe area where one is shown, and away from the profile-photo corner on X and LinkedIn.
