Why this matters
Your channel art, cover photo, and page header are the first thing visitors see on almost every social platform. A blurry, misaligned, or incorrectly sized banner immediately signals low production quality, regardless of how good your actual content is. The problem is that each platform has different dimension requirements — YouTube wants 1280 by 360, Facebook needs 1200 by 628, Twitter uses 1500 by 500, and LinkedIn expects 1584 by 396. Creating one design and resizing it manually in image software is tedious and error-prone.
Most banner creation tools fall into two frustrating categories: fully featured design apps that require a learning curve and a paid subscription, or template pickers that lock you into someone else's layout with minimal customization. What many people actually need is something in between — a tool that lets you set the exact platform dimensions, choose your own colors and text, and export a clean PNG without watermarks, accounts, or file-size limits.
This banner maker uses the Canvas API to render gradient backgrounds with your custom headline and optional subtitle at the exact pixel dimensions required by each platform. The output is a PNG file at native resolution, ready to upload directly. There are no layers to manage, no fonts to install, and no export settings to configure — type your text, pick your colors, select your platform, and download.
Reference table
| Platform | Dimensions (px) | Aspect ratio | Use case |
|---|---|---|---|
| YouTube | 1280 x 360 | ~3.56:1 | Channel art / banner |
| 1200 x 628 | ~1.91:1 | Cover photo, ad creative | |
| Twitter / X | 1500 x 500 | 3:1 | Profile header |
| 1584 x 396 | 4:1 | Company or profile banner | |
| Custom | 1000 x 400 | 2.5:1 | General-purpose header |
How to use it
Type your headline text and an optional subtitle line beneath it.
Pick two gradient colors that will blend across the banner background and set your preferred font size.
Choose a preset size for your target platform — YouTube, Facebook, Twitter, LinkedIn — or select Custom for a 1000 by 400 default.
Click Download to export the banner as a PNG file at the exact dimensions you selected.
Testing your result
After downloading the PNG, open it in any image viewer and verify two things: the dimensions match the platform's requirements exactly (right-click the file and check properties), and the text is fully visible and not clipped at the edges. Then upload it to the target platform and check the live preview. Social platforms often crop banners on mobile differently than on desktop, so view both versions. If text is getting cut off on mobile, shorten your headline or reduce the font size.
Common mistakes
Using text that is too long for the banner width, which causes the text to extend beyond the visible area on smaller screens.
Choosing two gradient colors with similar brightness, which creates a flat, washed-out background with no visual contrast.
Forgetting that YouTube shows channel art differently on mobile — the safe area for visible content is much narrower than the full 1280 by 360 canvas.
Using a custom size that does not match any platform's requirements, resulting in automatic cropping or distortion when uploaded.
Edge cases and options
The Custom size option produces a 1000 by 400 pixel banner, which works as a general-purpose header for blogs, email headers, and Slack workspace backgrounds. The Canvas API renders text at the specified font size, but very long headlines may exceed the canvas width. If your text is getting clipped, the solution is to shorten the headline or reduce the font size. The tool exports PNG at the native canvas resolution with no compression artifacts, so the file is crisp at the intended display size but may look soft if scaled up significantly.
Real-world use cases

Frequently asked questions
Q: Is it free?
A: Yes, completely free with no limits and no watermarks.
Q: Are my designs uploaded?
A: No. Everything runs in your browser via the Canvas API. The PNG is generated and downloaded locally.
Q: What dimensions are supported?
A: YouTube (1280 x 360), Facebook (1200 x 628), Twitter (1500 x 500), LinkedIn (1584 x 396), and a 1000 x 400 custom size.
Q: What export format is used?
A: PNG at the native canvas resolution, ready to upload directly as channel art or a cover photo.
