Why use this tool
Made for sensitive material
Hiding text in an image is different from softening it. A black box removes the visible pixels entirely and is the right choice for highly sensitive content like passwords, ID numbers, or confidential identifiers.
Pixelate offers a middle ground while Blur can look more natural in some contexts. All three methods keep the rest of the image intact so you can still share the useful parts.
Every method is applied entirely in your browser. Your image never leaves your device and you do not need to install software.
Questions
Frequently asked questions
What is the most secure way to hide text in an image?
Black Box is the most secure. It replaces the selected area with solid black pixels so there is no way to recover the original text from those pixels.
Can blurred text ever be recovered?
Blur makes text extremely difficult to read for normal use cases. For highly confidential text, Black Box gives the strongest visual certainty.
Can I hide multiple lines or blocks of text?
Yes. Draw a separate selection box over each piece of text. You can add as many covered areas as needed.
Does this work on handwritten text?
Yes. The tool hides any visible content within the selection, including printed text, handwriting, numbers, and symbols.
Will it be obvious that text was hidden?
Yes. It will be clear that something was intentionally removed, which is standard practice in legal documents, redacted records, and sanitized screenshots.
Can I hide text in a multi-column layout?
Yes. You can draw multiple separate boxes, one per column or one per text block.
Does a black box look unprofessional?
No. Black box redaction is widely recognized as the standard method for formally redacting documents and images.
Can I hide part of a chart, table, or graph?
Yes. You can draw a selection over any region of the image, including chart labels, table cells, axis values, and legends.
What happens if my selection does not fully cover the text?
Use Undo to remove the selection and redraw it slightly larger so that all sensitive text is covered.
