Frequently Asked Questions

What is a mosaic pixel art converter?
A mosaic pixel art converter transforms any regular image into a pixelated, blocky style reminiscent of classic 8‑bit and 16‑bit video games. It works by reducing the image resolution into larger color blocks (pixels) and optionally limiting the color palette to create that nostalgic retro aesthetic.
How does the pixelation process work?
The tool downsamples your image to a much smaller resolution based on the pixel block size you choose, then scales it back up using nearest-neighbor interpolation (no blurring). This preserves sharp block edges. Additionally, color quantization reduces the number of unique colors per channel, mimicking the limited palettes of retro hardware like the NES or Game Boy.
What image formats are supported?
Our tool supports all common image formats: JPEG, PNG, WebP, GIF, and BMP. The output is always a high-quality PNG file. Animated GIFs will be processed as a single frame (the first frame is used for conversion).
Is my image uploaded to any server?
No. All processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device — no server upload, no data collection, complete privacy. You can even use this tool offline once the page is loaded.
What pixel size should I choose for the best result?
It depends on your goal. For a classic 8‑bit look, try pixel sizes between 6–12. For a subtle mosaic effect, use 16–24. For extreme pixel art with very few blocks, go above 32. Experiment with different combinations of pixel size and color depth to find your perfect style — the preview updates in real time!
Can I use the generated pixel art commercially?
Yes, absolutely. The pixel art you create from your own images belongs to you. There are no watermarks added, and you can freely use the output for personal projects, social media, avatars, merchandise, or commercial work. We place no restrictions on the generated images.
What are the preset styles based on?
The presets are inspired by real retro hardware limitations: 8‑Bit Classic emulates the NES with its 512-color master palette; GameBoy Style mimics the 4-shade olive monochrome display; 16‑Bit Era reflects the richer color capabilities of the SNES and Sega Genesis; and Retro Arcade captures the chunky pixel look of early arcade cabinets.
