Hide Text in Image
Cover text in photos and screenshots with black box, blur, or pixelate based on how strong the redaction needs to be.
Same local editor as the homepage. This page is a deep link for one job, not a separate upload service.
Blur
Softer cover. Raise the strength until text is unreadable.
Pixelate
Mosaic blocks for faces and photos. Larger blocks hide more.
Black Box
Solid cover for names, IDs, and anything that must not be readable.
How to use
How do you redact this image locally?
Load the image in this browser, draw over each sensitive region, and export a PNG. The canvas edit does not upload the file. Paste a screenshot with Ctrl+V or Command-V, or drop a JPG, PNG, or WebP. Undo fixes a box without changing the original on your device.
- 1
Upload the image containing the text you want to hide.
- 2
Choose your hiding style: Black Box fully covers the text, Blur creates a frosted effect, and Pixelate creates a mosaic.
- 3
Click and drag over the text you want to hide. Draw a box that fully covers it.
- 4
Repeat for every piece of text that needs to be hidden.
- 5
Click "Export redacted PNG" to save the version with the text permanently hidden.
You can also paste a screenshot with Ctrl+V or ⌘V. Undo and Redo fix a box without changing the original file.
Why use this tool
Why does this stay in the browser?
This page is for images that already contain private material. Blur, pixelate, and black box run in your browser, so the file is not sent away to be cleaned. Use a black box for secrets that must not stay readable. Use blur or pixelate only after you have checked that the cover is enough.
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
What should you know before you export?
The image is processed locally, and export writes a new PNG. Blur is not the same cover as a black box. Paste works with Ctrl+V or Command-V. If your question is about a specific leak, such as a password, a face, or a sidebar, use the guides linked below before you send the file.
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.
Related workflows
Which related tool should you open next?
Every tool on this site is the same local editor with a different starting note. Open a related page when the job is narrower, such as faces, screenshots, or solid black text. You do not upload the image to a second service to switch jobs.
Guides
Which guide matches this job?
Read the guide that matches the mistake you are about to make. Text secrets usually need a black box, not a light blur. Faces, plates, and sidebars need their own pass. Local editing matters most when the file should not be uploaded in order to hide it.
