Trim Images Online

Automatically detect and remove empty pixels from image edges. Minimize image dimensions by trimming transparent or solid color borders.

What is Image Trimming?

Image trimming automatically detects and removes empty or uniform pixels from the edges of your image. This includes transparent areas (for PNG images) or solid color borders (like white or black margins). The result is a minimized image that contains only the essential content.

Why Trim Images?

Trimming images removes unnecessary whitespace and transparent borders, reducing file size and ensuring consistent dimensions across multiple images.

Yes! Use the Padding setting to add back a specific number of pixels around the trimmed content. This is useful when you want consistent spacing.
Yes! Transparent mode works best with PNG and WebP. Background Color mode works with all formats including JPG, PNG, GIF, and WebP.
