A social media post is a message that is created and published on one of the social media platforms.  It may include text, images, videos, links to pages, and other content.

Sharing content to social media platforms can be as easy as creating a URL. Whether you're a developer or marketer, these ready-to-use links let your visitors share posts without needing any SDK or JavaScript integration.

## Post on Facebook

To share a post on Facebook, you can use the following HTML code snippet. This will create a link that, when clicked, will open a new tab to share the specified URL on Facebook.

```html
<a 
  href="https://www.facebook.com/sharer/sharer.php?u=https://renderform.io" 
  target="_blank" 
  rel="noopener">
  Share on Facebook
</a>
```

Example: [Share on Facebook](https://www.facebook.com/sharer/sharer.php?u=https://renderform.io)

> Use `target="_blank"` to open the link in a new tab, and `rel="noopener"` for security reasons.

## Post on X (Twitter)

X (formerly known as Twitter) allows you to share content easily with a simple link. Below is the HTML code snippet to create a post on X:

```html
<a 
  href="https://twitter.com/intent/tweet?text=RenderForm is great!&url=https://renderform.io">
  Share on X
</a>
```

X allows you to share a message along with a URL. The `text` parameter is the message you want to share, and the `url` parameter is the link you want to include.

Example: [Post on Twitter](https://twitter.com/intent/tweet?text=RenderForm%20is%20great!&url=https://renderform.io)

```

## Share on WhatsApp

WhatsApp “click-to-chat” links allow direct messaging or sharing:

```html
<a href="https://wa.me/?text=Check%20out%20RenderForm:%20https://renderform.io">
  Share on WhatsApp
</a>
```

Or to a specific number:

```html
<a href="https://wa.me/15551234567?text=Hello%20there!">
  Chat on WhatsApp
</a>
```

Example: [Share on WhatsApp](https://wa.me/?text=Check%20out%20RenderForm:%20https://renderform.io)

```html
<a href="https://pinterest.com/pin/create/button/?url=https://renderform.io&media=https://renderform.io/render-form.svg&description=Check%20out%20RenderForm">
  Share on Pinterest
</a>
```

It includes parameters for the URL, media (image), and description.

## How to open post sharing in a new tab?

To tell web browser to open a sharing post in a new tab you need to use `target='_blank'` in `<a>` tag.

`rel="noopener"` is used to prevent the new page from having access to the `window.opener` property, which can help prevent security vulnerabilities.

```html
<a href="https://renderform.io" target="_blank" rel="noopener">Open in new tab</a>
``` 

## Notes and best practices

- **Security**: Always use `rel="noopener"` when using `target="_blank"` to prevent security vulnerabilities. 
- **Mobile Optimization**: Ensure that the links are mobile-friendly, as many users will share content from their mobile devices.
- **Meta Tags**: For platforms like Facebook, Twitter, and LinkedIn, ensure your page has appropriate Open Graph and Twitter Card meta tags to control how the shared content appears.
- **Facebook**: Only the URL is passed via `sharer.php` all title/summary/image data must be set in your page meta tags 
- **WhatsApp**: Use `wa.me/` with `?text=...` for sharing; for business use, include the phone number 

## Testing

To test these links, simply copy the HTML code snippets into your web page and click the links. They should open the respective social media platforms with the pre-filled content ready to share.

How to share a post with just a link?


Images are still one of the most effective ways to capture attention on social media. In 2025, as engagement competition intensifies, it is crucial to use up-to-date image specs. Below is a refined guide to Facebook's current recommended dimensions for profiles, posts, stories, events, and ads.

## Profile & Cover Photos

Facebook's profile and cover photos are the first things people see when they visit your page. They should be visually appealing and represent your brand or personal identity effectively.

### Profile picture

The profile picture is your visual identity on Facebook. For businesses, it's often your logo, while for individuals it's a photo that represents who they are. Although Facebook displays it in a circular frame, uploading a high-resolution square image ensures clarity and prevents key elements from being cropped.

- **Recommended upload**: 720 x 720 px (or larger; Facebook compresses intelligently)
- **Display sizes**: 176 x176 px on desktop, 196 x 196 px on mobile
- **Tip**: Keep key content like faces or logos in the center to avoid circular cropping cutting off important details.

![Facebook profile photo size](/blog/facebook/profile-photo-size.png)

### Cover Photo (Personal/Page)

Your cover photo sits right at the top of your profile or page and offers a larger canvas to express yourself or convey brand identity.

- **Upload size**: 820 x 312 px minimum
- **Safe and crisp**: Save at 851 x 315 px for best results across screen resolutions
- **Mobile responsiveness**: Facebook crops on mobile—design with central alignment in mind
- **File type**: JPG or PNG under 100 KB recommended for fast loading

![Facebook cover photo size](/blog/facebook/cover-photo-size.png)

### Group & Event Covers

Cover dimensions vary across Facebook surfaces. Here's how to make each one stand out:

- **Group Cover Photo**: 1640 x 856 px (recommended) (or 1.92:1 aspect ratio)
    - Ideal for welcome messages, themes, or weekly updates
    - Avoid placing text near corners due to auto-cropping on smaller screens
- **Event Cover Photo**: 1200 x 1005 px (recommended) (1.91:1 aspect ratio)
    - Perfect for event promotions, featuring key details like date and location
    - Ensure text is legible on both desktop and mobile views

## Feed Posts & Link Shares

Facebook feed posts are the bread and butter of engagement on the platform. The right image dimensions can significantly impact how your content is perceived and interacted with.

### Image Posts

Facebook supports a variety of aspect ratios for feed images, and the right choice depends on how you want the image to appear on both desktop and mobile.

- Square (1:1): 1080 x 1080 px - versatile, classic, and neat on all platforms
- Portrait (4:5): 1080 x 1350 px - ideal for mobile-first audiences
- Landscape (1.91:1): 1200 x 628/630 px - best for link previews or landscape images

![Facebook image post size](/blog/facebook/image-post-sizes.png)

Tips for image posts:
- Stick to 1200px width minimum to avoid blurry uploads
- Upload PNG for graphics/text-heavy images; JPG for photos
- Keep file size under 30 MB for faster loading

### Link Shares

When you share a link, Facebook pulls a thumbnail, title, and description from the metadata. Optimize the thumbnail to encourage clicks:

- Image Size: 1200 x 630 px
- Minimum width: 600 px
- Use the Open Graph (og:image) tag on your website to control which image appears

![Facebook link share image size](/blog/facebook/link-share-image-size.png)

> For Facebook link shares, ensure your images are visually engaging and relevant to the content. This will help increase click-through rates and engagement. 

## Stories & Reels

Stories are one of the most engaging content formats on Facebook in 2025. They appear at the top of the app and are usually consumed quickly and full-screen.

- **Optimal size**: 1080 x 1920 px (aspect ratio 9:16)
- Safe zones: Leave about 250 px at the top and bottom to avoid UI overlays (profile icon, reply box, etc.)
- Best formats: PNG or JPG under 30 MB

Use these for behind-the-scenes content, announcements, or limited-time offers. Facebook also supports interactive elements like polls, emojis, and swipe-up links (for eligible pages).

## Videos & Video Ads

Facebook video remains a powerful storytelling tool, especially with auto-play in feeds and sound-off default behavior.

### Feed Videos

Videos in the feed can be a great way to engage your audience. The recommended dimensions for Facebook feed videos are:
- **Landscape**: 1280 x 720 px (aspect ratio 16:9)
- **Vertical**: 1080 x 1350 px (aspect ratio 4:5)
- **Square**: 1080 x 1080 px (aspect ratio 1:1)

Facebook videos guide:
- Max video length: 240 minutes
- Ideal length: Under 2 minutes (keep under 15 seconds for Reels)
- File size: Up to 4GB
- Formats: MP4 or MOV
- Frame rate: 30fps recommended

![Facebook video size](/blog/facebook/video-sizes.png)

### Reels / Vertical Video

Reels are the fastest-growing format on Facebook, mimicking Instagram and TikTok-style full-screen short-form video.

- **Size**: 1080 x1920 px
- **Length**: 3 to 90 seconds
- Keep the center 1080 x 1420 px free of text for better readability

![Facebook Reels size](/blog/facebook/reels-size.png)

### Cover Videos

Although less common today, some pages still support cover videos. These can add dynamic flair to your Page.

- Recommended: 820 x 456 px (centered visual focus)
- Length: 20-90 seconds
- Looping: Yes

## Image Ads & Carousels

Facebook Ads are a vital part of every digital marketing strategy. Here's how to make them look great:

### Image Ads
Image ads are straightforward and effective. The recommended dimensions for Facebook image ads are:

- **Feed ads**: 1080 x 1080 px (square) or 1200 x 628 px (landscape)
- **Story ads**: 1080 x 1920 px
- **Messenger ads**: 1200 x 628 px

Best practices:
- Keep text under 20% of the image for optimal reach
- Use high-contrast, bright visuals to grab attention
- Carousel tip: Make all images the same size and aspect ratio (typically 1:1)

### Carousel Ads

Carousel ads allow you to showcase multiple images or videos in a single ad, each with its own link. This format is great for storytelling or displaying multiple products.

- **Card size**: 1080 x 1080 px
- **Cards per ad**: 2 to 10
- Add CTA buttons and URLs per card for eCommerce
