Question 1

Are files uploaded?

Accepted Answer

No. Decoding and export happen in this tab. Closing the page clears the images from memory.

Question 2

Is this really free?

Accepted Answer

Yes — no account or output watermark. Practical limits depend on browser memory and image dimensions.

Question 3

Does it cut around hair?

Accepted Answer

No — it swaps colors close to the sampled corner. Uneven scenes will leak.

Question 4

Which colors are preset?

Accepted Answer

White, blue, and red shortcuts cover the most common ID and visa backgrounds.
