How to Create Social Media Images for Free

You do not need Canva or Photoshop to create great social media images. Here is how to do it with free tools.

Image Sizes for Every Platform

Step 1: Choose Your Format

Start with a high-quality original image. Convert it to the right format using our tools:

• JPG to PNG — for images with text or logos
• PNG to JPG — for photos (smaller file size)
• JPG to WebP — for websites (smallest files)

Step 2: Resize for Your Platform

Use our Image Resizer with platform presets:

1. Upload your image

2. Select your target platform

3. Choose multiple platforms to generate all sizes at once

4. Download individually or as a ZIP file

Step 3: Optimize Image Quality

Compress your images without visible quality loss:

• Use our Image Compressor
• Set quality to 80-85% for photos (60-80% smaller files)
• PNG at maximum quality for graphics with text

Platform-Specific Tips

Instagram

• Square (1:1) is standard, but portrait (4:5) gets more engagement
• Use high contrast colors to stand out in the feed
• Add text overlays sparingly (most users browse on mobile)

YouTube

• Thumbnails are the #1 factor for CTR — use our Thumbnail Maker
• Use close-up faces and bright colors
• Keep text to 3-4 words maximum

Facebook

• Landscape (1.91:1) performs best in the news feed
• Use minimal text (Facebook's algorithm prefers images with less text)
• Bright, warm colors get more engagement

Batch Processing for Multiple Platforms

Need the same image in multiple sizes? Upload once, select all platforms, and download all sizes in one ZIP file. Use our Batch Image Resizer.
