Frequently asked questions
What counts as "border"?
Rows and columns whose color matches the image corner within the chosen tolerance.
What if my background is not uniform?
Auto-crop works with flat backgrounds. For complex ones use manual crop.
Which formats are accepted?
JPG, PNG, WEBP, AVIF, BMP and GIF (first frame). The output keeps the original format when possible.
Is my image uploaded to a server?
No. All processing happens on your device using the browser itself; the image never leaves it.
