How to Use
- Upload your image using the file uploader.
- Select your preferred pixelation style (Square, Mosaic, Triangular, or Hexagonal).
- Adjust the pixel size using the slider - smaller values create finer details, larger values create chunkier pixels.
- For more control, toggle "Selective Pixelation" and draw a selection box on the image to pixelate only that area.
- Enable "Preserve Edges" to maintain sharp details while pixelating smoother areas.
- Select your preferred export format (PNG, JPG, or WebP).
- Click "Apply Pixelation" to process your image.
- Use the "Undo", "Redo", or "Reset" buttons to experiment with different settings.
- Click "Download" to save your pixelated image when you're satisfied with the result.
Pixelation Styles Explained
Square Pixelation
The classic pixelation style that divides the image into a grid of squares. Each square is filled with the average color of the corresponding area in the original image. This creates the traditional "blocky" pixel art look popular in retro games and digital art.
Mosaic Pixelation
Similar to square pixelation but with an offset pattern between rows, creating a more tile-like appearance. This style adds visual interest and can produce a more natural look for certain images, especially photographs with organic content.
Triangular Pixelation
Uses triangular cells instead of squares, creating a geometric tessellated pattern. Each pixel block is divided into two triangles, with each triangle filled with the average color of the corresponding area. This creates a unique crystallized effect that adds dimension to the image.
Hexagonal Pixelation
Approximates a honeycomb pattern using hexagonal cells. This creates a more organic-looking pixelation effect that can be ideal for natural scenes and portraits. The hexagonal pattern provides a smoother transition between areas while still maintaining the pixelated aesthetic.
Technical Details
Edge Preservation
When enabled, the "Preserve Edges" feature uses edge detection algorithms to identify important boundaries and details in your image. The tool then selectively applies pixelation, maintaining original image data along detected edges while pixelating smoother areas. This creates a hybrid effect that keeps crucial details intact.
Private Processing
All image processing happens directly in your browser using HTML5 Canvas technology. Your images are never uploaded to any server, ensuring complete privacy and security, especially important when working with sensitive documents or personal photos.
Export Formats
PNG: Best for images with transparency or where quality is paramount. Lossless compression.
JPG: Ideal for photographs and images with many colors, resulting in smaller file sizes. Some quality loss.
WebP: Modern format that offers superior compression and quality, but may not be supported by all applications.
Frequently Asked Questions
What image formats are supported?
You can upload images in PNG, JPG, JPEG, GIF, and WebP formats. The tool will process any standard image format that your browser supports.
Is there a file size limit?
Yes, the maximum file size is 10MB. This ensures the tool remains responsive and performs well within the browser environment. For larger images, consider resizing them before uploading.
Can I undo pixelation once it's applied?
Yes! The tool provides undo, redo, and reset functionality. You can experiment with different pixelation styles, settings, and selections, then use the undo button to go back to previous states. The reset button instantly reverts to your original image, allowing you to try entirely new effects without reloading the page.
Is selective pixelation enough to hide sensitive information?
For casual use, selective pixelation can hide information from casual viewing. However, for truly sensitive data (like personal identifiers or financial information), be aware that advanced techniques might potentially recover some information. For maximum security, consider using larger pixel sizes or completely removing sensitive information before sharing.
Why should I use edge preservation?
Edge preservation is ideal when you want to maintain the recognizability of subjects while still applying a pixelated effect. It's perfect for creative photo effects where you want a stylized look without completely obscuring important details like facial features or text.
