• Use High-Resolution Originals: Start with a larger or high-quality image.
• Crop Before Resizing: Match the 3:4 ratio before resizing to prevent stretching.
• Choose the Right Format: PNG for crisp graphics, JPEG for photos, WebP for web use.

File Format Considerations

Each format serves a purpose depending on your needs:

• JPEG: Great for fast-loading, compressed photos and content.
• PNG: Best for logos, icons, and transparent images.
• WebP: Combines small size and high quality—ideal for websites.

Common Mistakes to Avoid When Resizing Images

Skipping the Crop Step

If the original image isn't vertical, resize results may look stretched. Crop the image to a 3:4 ratio before resizing.

Overcompressing the Image

Too much compression can ruin details. Use medium-to-high quality settings for best results.
