For text or license plates where hard edges matter, mosaic + PNG is usually the safer choice. For faces that should look more natural, blur + PNG/WebP often works better.

What is the Face Blur Tool?

The Face Blur Tool is an online image editor that lets you quickly hide areas that should be covered right away, such as faces, license plates, or parts of documents, directly in your browser. After uploading an image, you can click or drag on the canvas to apply blur or mosaic immediately and save the result without installing extra software.

People search for this tool using phrases like “face blur,” “hide face in photo,” “license plate mosaic,” or “blur personal information,” but the core need is usually the same. This tool is designed to hide faces or sensitive details fast and let you correct mistakes immediately with undo and redo.

When is it useful?

It is especially useful when you want to hide a specific person’s face before sharing or uploading a photo, cover a vehicle plate or document with an address, or quickly blur only the sensitive text in a screenshot. A single click handles small spots, while dragging lets you cover a connected area in one pass, making it a good last check before posting to social media.

  • Hide only some faces in family or group photos
  • Cover plates or personal info in marketplace, review, or report images
  • Blur names, phone numbers, or account numbers in document or chat captures
  • Partially anonymize sensitive details in internal company or report images

Key features

The tool focuses on the features people use most often. You can switch instantly between blur and mosaic, adjust brush size and strength, and apply the effect right away with click or drag controls. Undo and redo make it easy to fix only the part that went wrong, and PNG, JPEG, or WebP export stays on the same screen.

  • Switch between blur and mosaic effects
  • Apply with a single click or continuous drag
  • Adjust brush size
  • Adjust effect strength
  • Undo / Redo / Restore original
  • Download as PNG / JPEG / WebP
  • Privacy protection through browser-only processing

How to use it

First upload an image, then choose either blur or mosaic in the settings area on the right or below. Next, set the brush size and strength, then click or drag on the canvas to edit immediately. If you do not like the result, undo the last step. If you want it back, redo it, then download the final file.

  1. Upload an image.
  2. Choose blur or mosaic.
  3. Adjust brush size and strength.
  4. Click or drag over the area you want to hide.
  5. Use undo or redo if you need to adjust it.
  6. Save in PNG, JPEG, or WebP.

What is the difference between blur and mosaic?

Blur softens edges and works best when you want a more natural-looking cover. It helps when you want to distract attention from a face without changing the overall mood of the photo too much. Mosaic shows visible pixel blocks, so it is more effective when you need stronger anonymization for a license plate, account number, or part of a document.

It is usually faster and cleaner to choose a brush slightly larger than the area you want to hide. If the strength is too low, text or edges may still show through. For faces, a medium to strong blur is safer, while license plates and text usually need a fairly large mosaic cell. PNG is the safest export option, and WebP is also a good choice for web sharing.

  • Faces: blur + medium or stronger intensity
  • License plates / text: mosaic + larger cell size
  • Natural-looking photo sharing: mostly blur
  • Strong anonymization: mostly mosaic

Frequently asked questions

Is the uploaded photo stored on a server?

No. This tool processes the image only in your browser and does not upload or store it on a server. If you close the tab or refresh the page, your current edits are lost.

Should I choose blur or mosaic?

If you want to hide a face naturally while keeping the photo’s overall feel, blur is usually the better choice. If you need to cover a license plate, account number, or document text more aggressively, mosaic works better.

Can I go back to the previous state if I make a mistake?

Yes. The undo button cancels the most recent change, and redo brings it back if you need it again. If you want to reset the whole image, use Restore original.

Can I blur faces on mobile too?

Yes. You can edit with touch drag on smartphones and tablets, and the quick action buttons at the bottom let you undo or save right away.

Which export format should I choose?

PNG is the safest choice when quality matters most. If you want smaller files for the web, WebP is a strong option. JPEG creates lighter files, but edges can get a bit softer after repeated saves.

Does it support automatic face detection?

This tool focuses on fast manual masking instead of automatic face detection. Because you click or drag over the exact area you want to hide, it works not only for faces but also for license plates, document text, and chat screenshots.
