Tool usage guide
Image Trim by Color is a precise utility designed to automatically remove unwanted borders or backgrounds from your images by identifying and cropping pixels that match a specific color.
Background
A collection of scanned receipts contains inconsistent white borders that need to be removed for a clean report.
Problem
Manual cropping is tedious and inconsistent across dozens of files.
How to use
Upload the receipt image, select 'White' from preset colors, and set tolerance to 20.
presetColors: 'white', colorTolerance: 20Outcome
The tool automatically detects and removes the white margins, leaving only the receipt content.
Background
Product photos were taken against a solid blue backdrop that needs to be removed.
Problem
The background color is uniform but needs precise trimming to avoid cutting into the product.
How to use
Upload the product photo, sample the color from the 'Top Left Corner', and adjust tolerance to 10.
You can upload and process JPEG, PNG, WebP, and TIFF image files.
The tolerance (0-50) determines how closely a pixel must match your selected color to be trimmed. Higher values include a wider range of similar shades.
Yes, enable the 'Sample Color from Image' option and choose a position like 'Top Left Corner' or 'Center' to automatically detect the color to be trimmed.
This mode allows you to detect color boundaries without generating a new file, which is useful for testing your tolerance settings.
Yes, you can select a different output format such as JPEG, PNG, or WebP, or choose to keep the original format.
