Quick answer

Use this preset when a destination asks for 512 × 512 pixels. Crop first if the source shape is different, then resize and verify the downloaded dimensions.

How it works

The 512 × 512 size is a practical target for uploads, graphics, previews, or layouts that need exact pixel dimensions.

  1. Upload the image you want to resize.
  2. Use the 512 × 512 pixel target.
  3. Choose crop, contain, or aspect-ratio lock based on whether the full image must remain visible.
  4. Download and verify the final dimensions.

Tips for the best result

  • Crop when the target aspect ratio differs and edge-to-edge fill matters.
  • Use contain mode when the full original must remain visible.
  • Avoid enlarging small sources for important submissions.

Why this workflow works

Practical benefits

Direct preset for 512 × 512 pixels.

Useful for exact portal, design, and publishing requirements.

Works alongside crop, contain, compression, and conversion.

Keeps verification steps close to the tool.

Aspect ratio

Check the shape before resizing

A pixel target also defines a shape. If the original shape does not match, decide whether to crop edges away or preserve the full image with empty padding.

Common mistakes to avoid

  • Do not edit the only copy of your image. Keep the original before using this page.
  • Do not judge the result by file size alone. Open the downloaded image and check important details.
  • Do not stretch the image to 512 × 512 if the aspect ratio does not match. Crop or contain it instead.

Example workflows

  • Use this page when a site asks for exactly 512 × 512 pixels.
  • Square outputs work well for avatars, icons, product cards, and profile photos.
  • After downloading, inspect the file properties to confirm the final dimensions.
