Common Mistakes to Avoid:

 Even though image compression is easy, many beginners make small mistakes that reduce image quality or harm website performance. Avoid these common errors to get the best results.

❌ 1. Uploading Very Large Images Without Resizing

Many people upload high-resolution images straight from a camera or phone.
Always resize images to the required dimensions before compressing them.

❌ 2. Using Extreme Compression Settings

Over-compressing images can make them blurry or pixelated.
Choose smart or lossless compression instead of the highest compression level.

❌ 3. Using Untrusted or Low-Quality Tools

Random tools may reduce quality or add watermarks.
Use reliable and well-known image compression tools for safe results.

❌ 4. Forgetting to Rename Image Files

Uploading images with names like IMG_1234.jpg is bad for SEO.
Rename files using descriptive names like image-compression-example.jpg.

❌ 5. Not Adding Alt Text to Images

Alt text helps search engines understand images and improves accessibility.
Always add clear and keyword-relevant alt text.

❌ 6. Ignoring Image Format Selection

Using the wrong image format can increase file size.
Use JPG for photos, PNG for graphics, and WebP for websites.

❌ 7. Compressing the Same Image Multiple Times

Repeated compression can slowly reduce image quality.
Always compress from the original image, not from a compressed copy.
