How to use Trim Transparent Edges
Cut away empty transparent space around logos, stickers and cut-outs, or trim a flat background color such as the white margin around a scan. Each image is trimmed to its own content, and whole batches are processed in your browser.

Frequently asked questions
Are my images uploaded?
No. Trimming runs in your browser, and your images never leave your device.
Which output format should I use?
PNG or WebP, so the transparency survives. The output starts as PNG; JPG has no transparency, so see-through areas would turn white.
How does Solid background know which color to remove?
It checks the four corners and uses the color most of them share. The Detected background is shown in the panel; raise Color tolerance if JPEG noise stops the trim too early.
Why is a faint shadow still kept?
With Alpha threshold at 0, any pixel that is even slightly visible counts as content. Raise the threshold to treat almost invisible pixels as empty.
Can I trim many images at once?
Yes. Each image is trimmed to its own content with the same settings, and the results download one by one or as a single ZIP.
How is this different from Crop Image?
Crop Image cuts an area you choose by hand. This tool finds the content edges for you, which suits batches of logos, icons or scans.
