Social Media Image Maker

Every social network shows your image at a specific size, and getting that size wrong is the fastest way to look unpolished: text gets cropped, photos blur from upscaling, and banners end up letterboxed with awkward bars. The Social Image Maker above fixes this by locking the canvas to each platform’s exact pixel dimensions, so what you design is exactly what people see. Pick a platform, add your text and a background, and download — free, with no watermark and no account.

The sizes that matter

Here are the current upload sizes the tool builds in. Designing at these exact dimensions means no surprise cropping when you upload.

• YouTube thumbnail — 1280×720 (16:9). The most click-sensitive image you’ll make. Short, bold text wins.
• X / Twitter header — 1500×500 (3:1). A wide banner; your avatar overlaps the lower-left.
• Facebook cover — 1640×924. Uploaded large for sharpness; displayed around 820×312 on desktop and 640×360 on mobile.
• LinkedIn banner — 1584×396 (4:1). The strip behind your headshot; keep text upper-right.
• Twitch banner — 1200×480. Profile banner for your channel page.
• Instagram post — 1080×1080 (1:1). The reliable square for feed and grid.
• Instagram story — 1080×1920 (9:16). Full-screen vertical for stories and reels covers.
• Open Graph card — 1200×630 (1.91:1). The link-preview image shown when a page is shared anywhere.

How to make a social image, step by step

1. Pick a platform

Choose the network you’re designing for. The canvas instantly snaps to that platform’s exact size, and the live preview always shows the true aspect ratio — square for Instagram, ultra-wide for LinkedIn, vertical for stories. There’s nothing to configure; the dimensions are correct from the first click.

2. Add your headline and sub-text

Type a headline — the main message — and an optional sub-text line underneath. You can set the colour of each, scale the headline up or down, choose left / centre / right alignment, and position the block at the top, middle, or bottom of the canvas. Turn on bold for impact and shadow for contrast against busy backgrounds. The text wraps automatically to fit the width, and you can press Enter for an explicit line break.

3. Choose a background

Three options cover almost every design:

• Gradient — pick from a set of curated two-colour gradients. Gradients look modern, keep text readable, and never need a stock photo.
• Solid — a single brand colour, clean and minimal.
• Photo — upload your own PNG, JPG, or WebP. It’s scaled to cover the canvas (no stretching), and a Darken slider drops a dark overlay over it so your text stays legible no matter how bright the photo is.

Set an accent colour to match your brand; it’s used for the accent bar beside or beneath your text.

4. Export and download

Choose a format and click Download. The image is rendered at the platform’s full native resolution — not the small preview — so it’s crisp when uploaded.

Which format should you pick?

• PNG is lossless and razor-sharp on text, flat colours, and gradients. It’s the best default for most thumbnails and cards, and the only one that would keep transparency (though social images are usually full-bleed).
• JPG produces much smaller files for photographic backgrounds. Keep the quality slider around 85–95 to avoid visible artefacts around text.
• WebP gives the smallest files at good quality and is supported by every modern browser and platform. Use it when file size matters most.

Design tips that actually help

Use few words. Especially on thumbnails and preview cards, your image is seen small. Three to five strong words beat a full sentence every time.

Respect the safe zones. On profile banners, an avatar or your name overlaps part of the image. Keep key text in the upper-right on LinkedIn, the top or centre on X, and roughly centred on Facebook so nothing important is hidden.

Lean on contrast. Dark text on a light area, or light text on a darkened photo, is readable at any size. The shadow toggle and the darken overlay exist precisely for this.

Stay consistent. Re-using the same wording, colours, and accent across platforms makes your brand instantly recognisable. Design once, then switch the platform and re-export the same idea at each size.

What is an Open Graph image, and why make one?

When you paste a link into a social post, Slack, iMessage, or WhatsApp, the platform looks for the page’s Open Graph tag (og:image) and shows a preview card. A blank or low-quality preview makes a link look untrustworthy; a clean, branded 1200×630 card makes it look professional and gets more clicks. Use the OG image generator preset to create one with your page title and site name, then reference the exported file from your page’s og:image meta tag (the same image also works as a Twitter / X summary_large_image card).

Is it private, and where does the work happen?

The image is composed and rendered in your browser using the standard HTML canvas — the file you download is created on your own device. There’s nothing to install and no account to create. How any data associated with the tool is handled is described in our privacy policy.

Frequently overlooked details

• Instagram square vs story: use 1080×1080 for feed posts and 1080×1920 for full-screen stories — they’re different shapes, so pick the right one before designing.
• Facebook mobile crop: the mobile view trims the cover differently from desktop; centring content avoids losing it.
• Thumbnail duration badge: YouTube overlays the video length in the bottom-right of a thumbnail, so keep text out of that corner.
