File Steganography packs any file into a PNG by writing bits across R, G, and B LSBs, preserving the original file name and bytes.

1. Upload a PNG carrier and any secret file.

2. Check capacity vs file size.

3. Download the stego PNG.

4. Later upload that PNG to extract and download the original file.

Carry documents inside images without cloud storage.

Files never leave your browser during hide or extract.

How much can I hide?

About (width x height x 3) / 8 bytes, minus a small header for the file name.

Will JPEG work?

No. Use PNG only so the hidden bits survive.
