How to Resize Images for Social Media

Creating the perfect image for Instagram or Threads can be tricky with different aspect ratios. Our free Image Resizer tool simplifies this process.

1. Upload your image: Select any PNG or JPEG file.

2. Choose your format: We offer presets for Square (1:1), Portrait (4:5), and Story (9:16) - the standard sizes for Instagram and Threads. You can also set custom dimensions.

3. Adjust and Crop: Use the zoom slider and drag your image to frame it perfectly. Choose 'Fill' to crop or 'Fit' to add background bars.

4. Download: Get your optimized image instantly, ready to post.

Why use this tool?

Properly sized images perform better on social algorithms. Avoid awkward cropping by the app and ensure your visual content looks professional.

How to Create Viral Threads

Long-form content is taking over, but formatting it for Threads or Twitter (X) is a hassle. This tool does the heavy lifting.

1. Write your content: Paste your article, blog post, or thoughts into the editor.

2. Auto-Split: We automatically break your text into individual posts based on character limits (500 for Threads, 280 for Twitter).

3. Preview: See exactly how your thread will look to your followers, complete with a bot avatar preview.

4. Copy and Post: Copy each segment with one click and paste it into your app.

Tips for better threads

Start with a strong hook in the first post. Use line breaks to make text readable. Number your posts (we do this automatically!) so readers follow the sequence.

Color Palette Extractor

Upload an image to extract its dominant color palette.

Extract Colors from Images

Consistency is key to building a personal brand. Our Color Palette Extractor helps you find the exact colors used in your favorite images.

1. Upload an Image: It could be a photo you love, a screenshot of a brand you admire, or your own logo.

2. Instant Analysis: Our algorithm scans the image pixels to find the most dominant and visually significant colors.

3. Get Hex Codes: We generate a 5-color palette with precise Hex codes (e.g., #FF5733) that you can copy and use in your designs.

Use cases

Create matching backgrounds for your stories. Design cohesive highlight covers. Ensure your text overlays match your photography.

Track Your Marketing Campaigns

If you aren't tracking your links, you don't know what's working. UTM parameters are the industry standard for tracking traffic sources.

1. Enter your URL: The page you want to send traffic to.

2. Set Source & Medium: Where is the traffic coming from? (e.g., 'newsletter', 'twitter') and how? (e.g., 'email', 'social').

3. Generate Link: We build the long URL for you automatically.

4. Use it: Paste this link in your bio, emails, or ads. Google Analytics will now show you exactly where your visitors came from.

Why UTMs matter

Stop guessing which tweet or email drove the sale. Use data to double down on what works.

Image Compressor for Social Media

Reduce image file size to fit platform limits like Bluesky's 1MB requirement.

Why Compress Images?

Social media platforms have file size limits. Bluesky limits images to 1MB, and large images can slow down uploads or fail entirely.

• Bluesky: 1MB per image limit

• Threads: Large images may upload slowly

• Twitter/X: 5MB for photos, 15MB for GIFs

• Instagram: Optimal under 8MB for best quality
