Pixelate Effect

Workflow & Usage

1. Add your images
   Drag a group of photos, paste them from clipboard, or click the dropzone. Previews appear instantly.

2. Adjust pixel size
   Use the global slider to set how blocky the output should be:

   • Small values = softer, subtle pixelation
   • Large values = strong mosaic effect

3. Preview results
   Each card shows a live pixelated preview at your chosen block size.

4. Manage your batch

   • Toggle Include in ZIP
   • Remove items you don’t need

5. Download

   • Single file: Click Download on any card
   • Batch export: Click Download all as ZIP to export everything at once

Everything runs fully in your browser — fast, private, and offline-friendly.

Use Cases

• Privacy protection
  Pixelate faces, license plates, screens, or sensitive details before publishing.

• Design & creative
  Create retro 8-bit-style graphics for social posts, visuals, or backgrounds.

• UI/UX mocks
  Pixelate content in screenshots to avoid exposing personal information in demos.

• Teaching & presentations
  Share examples or case studies without revealing private data.

• Meme & content creation
  Apply pixelation for comedic or dramatic emphasis.

Tips for Best Results

• Higher block size = more secure
  For privacy, use a block size of 20–40 or more to ensure details are unreadable.

• Pixelate before resizing
  If you plan to shrink images later, pixelate at a higher block size first.

• Use PNG/WebP for sharper edges
  These formats keep the block edges crisp compared to JPEG’s compression.

• Batch your workflow
  Prepare a whole folder of images, pixelate them together, then compress with
  Image Compressor for fast publishing.

How It Works

• Client-side Canvas processing
  The browser decodes the image, then creates a tiny downscaled version based on your slider value.

• Block rendering
  This small canvas is drawn back at full size with imageSmoothingEnabled = false, producing clean blocky pixels.

• Format preservation
  Downloads keep the same mime type and extension as the source (JPEG → JPEG, PNG → PNG, WebP → WebP).

• ZIP creation
  Multiple pixelated outputs are bundled with JSZip and delivered in one click.

• Privacy-first by design
  No servers. No uploads. No accounts. Everything stays local to your device.
