Everything you need in a free pixelate image tool

Pixelate any image

Turn JPG, PNG, and WebP photos into mosaic-style pixel art for privacy, design, social posts, and creative edits.

Intensity you control

Pick Light for a subtle mosaic, Medium for a classic pixel look, or Heavy for bold blocky squares.

100% browser-based

Everything runs locally on your device. Your photos never upload to Focera servers — private by design.

Before & after preview

Compare the original and pixelated result with a slider, then download a PNG ready to share or edit further.

How It Works

Pixelating an image should be fast and private. Focera keeps the whole flow on one page — upload, choose intensity, pixelate, compare, and download without an account or desktop installer.

  1. Upload your image. Drag and drop a JPG, PNG, or WebP file up to 10 MB, or click the zone to browse from your device.
  2. Pick an intensity. Light keeps finer detail, Medium is the classic mosaic look, and Heavy uses larger blocks for a stronger pixel effect.
  3. Pixelate and download. Processing runs in your browser. Compare with the before/after slider, then download a PNG.

Jump back to the pixelate image tool anytime to process another file.
