About Extract LSB
Extracts the Least Significant Bit data from each pixel in an image. This is a common way to hide data in Steganography.
Input: binary bytes (text input uses UTF-8; a file retains its original bytes). Output: binary bytes.

Before interpreting the result
File signatures and heuristics are clues, not definitive classification. Retain an original copy and compare exact bytes when investigating a file. A parser failure can also indicate truncated or unsupported data.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
