Chat screenshots, ID photos, license plates, faces — all need pixelation before sharing. Mosaic is the most common way to protect privacy. Many people think pixelating requires Photoshop, but online mosaic tools do it in seconds — local pixelation, face mosaics, and batch processing are all supported.
When to Pixelate an Image
When sharing images daily, lots of information needs protection:
- Personal info: ID numbers, phone numbers, addresses, names
- Chat records: avatars, nicknames, sensitive conversation content
- Faces: passersby, portraits involving privacy
- License plates, house numbers: vehicle info and location info
Before sharing, scan the image and pixelate whatever shouldn't be exposed — protecting both yourself and others.
How to Use an Online Mosaic Tool
With the PixelForge mosaic tool, it's very simple:
- Upload the image to pixelate
- Select the mosaic tool and brush over the areas to hide
- Adjust the mosaic block size (bigger = more concealment, smaller = finer)
- Export the pixelated image
Brushing is more flexible than box-selection, perfect for irregular areas like faces, plates, and chat bubbles. Make the mosaic blocks larger for more thorough pixelation that's hard to recover.
Mosaic vs Blur: Which to Choose
Two common pixelation effects: mosaic and blur.
- Mosaic: pixel blocks, strong concealment, good resistance to recovery
- Blur: overall softening, natural look, but some tools can reverse it
For sensitive info, choose mosaic over blur — more reliable protection. For non-sensitive areas, blur is fine.
Batch Pixelate Images
Processing multiple screenshots at once, like several chat records, batch pixelation saves major time. Upload all images, brush the areas to hide on each (positions are usually the same), and export uniformly. Batch processing is perfect for sharing multiple screenshots to social platforms.
