Design the card people see.

An Open Graph image is the 1200×630 preview that shows when your link is shared on X, LinkedIn, Slack, or iMessage. slsh.me lets you design one for any short link — headline, colors, logo — right in the form. No design tool, no upload, free.

Design your first card Preview any link

How it works

Three fields. No upload.

The designer lives inside the link form. Type, pick colors, done — the finished card is rendered and attached as the link’s social image when you save.

1

Open the link form

Creating or editing a link, find the Social image section and switch to Design a card.

2

Compose the card

Type a headline and subtitle, pick a background and a highlight color, and add your logo — or keep the slsh.me mark. The preview updates live.

3

Save — it’s your card

On save it renders to a 1200×630 PNG and becomes the link’s og:image. Re-open any time to edit it again.

The basics

What an Open Graph image actually is

When you paste a link into X, LinkedIn, Slack, Discord, or iMessage, the app reads the page’s og:image tag and renders a preview card. It’s the first — often only — thing a reader sees before deciding to click.

The card is a fixed 1200×630 px image at a 1.91:1 ratio (per the Open Graph protocol and platform docs). Get the size wrong and platforms crop it, letterbox it, or fall back to a tiny thumbnail.

  • Right size, every time — the designer outputs exactly 1200×630.
  • Standard og:image + twitter:card tags, written for you.
  • Want the spec in depth? Read the Open Graph image-size guide.

Free, not a feature gate

Most shorteners charge for this. We don’t.

Custom social images are a classic paid-tier upsell on other link shorteners. On slsh.me the designer is free on every link — no watermark, no per-link fee, no upgrade prompt.

Already have a finished image? The Upload tab is still right there. Design in-app when you don’t, upload when you do.

Renders everywhere

One card. Every platform that reads Open Graph.

slsh.me writes the standard Open Graph and Twitter Card tags, so the card you design shows up wherever the link travels.

Questions

Open Graph, answered.

What is an Open Graph image?
An Open Graph (OG) image is the preview picture that appears when a link is shared on social platforms and chat apps — X, LinkedIn, Facebook, Slack, Discord, iMessage and WhatsApp. It’s defined by the og:image meta tag and is the single biggest driver of whether a shared link gets noticed in a feed.
How do I create a custom Open Graph image for a link?
Edit any link, open the Social image section, and switch to Design a card. Type a headline and subtitle, pick a background and a highlight color, and add your logo or use the slsh.me mark. On save it renders to a 1200×630 PNG and becomes that link’s og:image — no upload and no separate design tool.
What size should an Open Graph image be?
1200×630 pixels, a 1.91:1 aspect ratio, under 1 MB, in PNG or JPG. That’s the size X, LinkedIn, and Facebook render as a large card. slsh.me’s designer outputs exactly 1200×630, so the card is always the right size. The image-size guide covers the edge cases.
Do I need Photoshop or Figma to make a social card?
No. The card is composed in your browser inside the link form — headline, subtitle, colors, and logo — with a live preview. There’s no external design tool, no exporting a perfectly-sized PNG, and nothing to upload.
Does designing a card cost anything?
No. The card designer is free on every link, with no watermark and no per-link fee. Most link shorteners gate custom social images behind a paid plan; slsh.me gives the designer away free.
Can I use my own logo and brand colors?
Yes. Upload a logo (it’s stored with the link and reloaded whenever you re-edit the card) or use the slsh.me mark, and choose from the brand background and highlight colors. The headline gets a marker-style highlight you can recolor or turn off.
Will the card show on X, LinkedIn, and Slack?
Yes. slsh.me writes the standard Open Graph and Twitter Card tags, so the designed card renders on X, LinkedIn, Facebook, Slack, Discord, iMessage, and WhatsApp. Confirm the result with the free Open Graph preview checker before you share.
Can I still upload my own image instead?
Yes. The Social image section keeps an Upload tab alongside Design a card. Upload a finished 1200×630 image when you already have one, or design in-app when you don’t — either becomes the link’s og:image.

Make every link look designed.
