FAQ
Which images can be extracted?
Images produced by our LSB embed tool or compatible RGB per-channel embedding work; plain images report no hidden data.
Why might extraction fail?
Recompression (e.g. converting to JPEG), cropping or resizing destroys low-bit data; lossless PNG stego images have the highest success rate.
Will my data be uploaded?
No, all parsing runs locally in your browser.
