🖼️ Add your main image

Start by uploading your favorite photo that you want to transform into a stunning mosaic. The tool supports JPG, PNG, and other common image formats.

Choose high-resolution images for the best results - the more detail in your original photo, the more impressive your final mosaic will be. The algorithm analyzes every pixel to create the perfect tile placement.

🧩 Choose your tile images

Upload your own collection of images to use as mosaic tiles or select from stock photo libraries.

The more diverse your tile collection, the richer and more detailed your final mosaic will appear. Mix landscapes, portraits, textures, and colors for best results.

Pictiler matches colors and tones automatically.

🎛️ Adjust tile size & effects

Fine-tune your mosaic with our intuitive controls. Adjust tile size to balance detail and recognition - smaller tiles create more intricate patterns.

Experiment with different settings to achieve the perfect balance between artistic effect and image clarity. Real-time preview shows changes instantly.

💾 Download high-quality results

Once your mosaic is complete, download it in high resolution - perfect for printing, sharing on social media, or using as wallpaper.
