Hide Text in Image

The Hide Text in Image tool allows you to securely encode and hide secret text inside a image file without noticeably altering the original file.

It uses LSB (Least Significant Bit) steganography to replace the least important bits of the image's pixels with the bits of your secret text.

Yes! All processing is done 100% locally in your web browser using JavaScript. Your files are never uploaded to our servers, ensuring absolute privacy.

To the naked eye, the steganographic image looks identical to the original. LSB changes are mathematically imperceptible without specialized analysis tools.

Yes, the maximum text size depends on the resolution of the image. A higher resolution image contains more pixels and can therefore store more text.

Yes! LSB steganography requires lossless formats. If you compress the output as a JPEG, send it via WhatsApp, or upload it to social media, the hidden data will be destroyed. This tool strictly outputs PNGs.

This tool uses a specific encoding algorithm (including custom magic bytes). It will only successfully extract text that was originally hidden using our corresponding Hide Text tool.
