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.

Frequently Asked Questions

Transparent mode detects and removes pixels with alpha transparency (works best with PNG images). Background Color mode removes pixels matching a specific color, useful for images with white or colored borders.
Tolerance controls how closely pixels must match to be considered 'empty'. A value of 0 requires an exact match, while higher values allow for slight color variations to be trimmed.
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.
If the entire image matches the trim criteria, you'll see an error message. Try adjusting the tolerance to a lower value or switching detection modes.
