How to use Trim Transparent Borders
Remove empty transparent margins around logos and PNGs.
- Choose images with transparency. Set padding in pixels, then trim. Each image is cropped to the smallest rectangle containing visible pixels.
- Process the selected files, then inspect the preview, dimensions or warnings.
- Download a new copy and check it before replacing or sharing the original.
How processing works
The tool scans pixel alpha values to find the outer bounds of visible content, expands that rectangle by your padding setting and exports the cropped image.
A quick example
Trim a logo with a large transparent border before placing it in a document.
Assumptions, edge cases & limits
- A faint shadow can extend the visible bounds.
- A solid white margin is opaque and is not removed by transparency trimming.
- Faint shadows count as visible content. This does not remove a solid background.
Questions about Trim Transparent Borders
Can this remove white borders from a logo?
Only if those borders are transparent. White pixels have visible color, so this tool keeps them. Use manual cropping for an opaque border.
Why is there still space around the trimmed image?
Check the padding setting and any faint shadow or semi-transparent pixels at the edges. Those pixels count as content and can enlarge the retained rectangle.
Are my files or inputs uploaded?
Calculation and file processing run in your browser without a processing upload. Downloads go to your device. Choosing a next-step transfer creates a temporary local copy for that workflow. Region preferences are stored separately from tool inputs. See our privacy details.
Can I use this tool for free?
Yes. No signup, subscription or payment is required to use the tool or download its output. File tools have device and size limits; a smaller batch may work better on a phone.
