🚀 When do you need to resize images?

  • Uploading to sites with limits: Many platforms require images smaller than 2 MB or with specific dimensions
  • Photos for Instagram or WhatsApp: Each network has an ideal size
  • E-commerce images: Marketplaces like Amazon and eBay have precise requirements
  • Presentation adjustments: PowerPoint or Google Slides need images in the right ratio
  • Video thumbnails: YouTube requires 1280×720px in 16:9

⚙️ How to resize an image — step by step

  1. Go to the resize tool on MyIMGKit
  2. Upload your image (JPG, PNG, WEBP)
  3. Set the desired width and/or height in pixels
  4. Choose "maintain aspect ratio" to avoid distorting the image
  5. Download the resized image

📏 Ideal sizes by platform

  • Instagram Feed: 1080×1080px (square) or 1080×1350px (portrait)
  • Instagram Stories: 1080×1920px
  • WhatsApp: max 1600×1600px for good quality
  • Facebook: 1200×630px for posts and links
  • YouTube Thumbnail: 1280×720px
  • LinkedIn: 1200×627px for shared posts

💡 Pro tip: Always maintain the original aspect ratio when resizing to avoid distorted images. Enable the "lock ratio" option in the tool.

🧠 Resize vs compress — what's the difference?

Many people confuse the two concepts:

  • Resize — changes the physical dimensions (width × height in pixels)
  • Compress — reduces the file weight (KB/MB) without changing dimensions

For best results, do both: first resize to the correct dimensions, then compress to optimize the file weight.
