Mosaic / Blur Image lets you cover only the parts of a photo that should not be visible. Draw one or more areas, choose mosaic or blur for each area, adjust the strength, and export the finished image.
Common use cases
Redact document regions
Blur or mosaic a name, address, account number or other selected area in a screenshot.
Mask arbitrary objects
Hide regions that an automatic face detector or text detector would not recognize.
How it works
1
You draw one or more rectangular regions over the image preview.
2
The browser maps those regions back to the source-image coordinates.
3
A blur or pixelated mosaic effect is rendered into those regions before export.
Privacy & file handling
Manual masking is local
The selected image and redaction regions are processed in the browser without requiring the source image to be uploaded to Zavilo.
Limitations and important notes
- You must select every sensitive region yourself; areas you miss remain visible.
- Blur may leave coarse visual information, while mosaic may still reveal shape and context.
- Other identifying information outside the selected areas can remain in the image.

Tips for better results

- Add separate areas when different parts of the photo need different effect strengths.
- The output is created at the original image dimensions even when the on-screen preview is smaller.
Frequently asked questions
Can I hide more than one part of a photo?
Yes. Draw multiple areas and adjust each area independently.
Can one area use mosaic and another use blur?
Yes. Each selected area can use its own effect and strength.
Will the downloaded image keep the original dimensions?
Yes. The effects are applied to an output canvas using the original image width and height.
