How can I pixelate an image online?

Use this image pixelator to turn a photo, screenshot, or design into a crisp block mosaic. Add your image, choose a block size, compare it with the original, and export at the source dimensions. Canvas processing happens in your browser, so the file is never sent to CanDoYa.

How to use

  1. 01
    Add an image

    Drop a PNG, JPG, or WebP file into the editor, choose one from your device, or load the built-in landscape example.

  2. 02
    Choose the block size

    Move the slider or select a preset. The live Canvas preview updates as the blocks become finer or chunkier.

  3. 03
    Compare the result

    Switch between Pixelated and Original to check which details the effect keeps or removes.

  4. 04
    Export the image

    Choose PNG, JPEG, or WebP, create the full-resolution result, then copy or download it.

Who it's for

  • Pixel artists and game developers can reduce a reference image into readable color blocks before redrawing a sprite or tile.
  • Designers and social teams can give photos, thumbnails, and poster graphics a deliberate retro digital look.
  • Teachers and craft makers can simplify a picture into a grid-like reference for mosaics, bead art, or classroom projects.
  • Editors and creators can test how much visual detail remains at different block sizes before choosing a final effect.

The live preview makes it easy to balance detail and blockiness before you create the full-resolution file. Use a small block size for a subtle digital texture, or larger blocks for retro artwork, game references, and bold mosaic effects.

Pixelation is a visual effect, not secure redaction. If text, a face, or another detail must be impossible to recover, cover it with an opaque shape and flatten the image instead.

FAQ

Is my image uploaded anywhere?

No. Your browser decodes, previews, pixelates, and exports the image on your device. CanDoYa does not receive the selected file or the finished result, although normal site analytics may still record that this page was visited.

Is the image pixelator free?

Yes. You can pixelate and download images without an account, subscription, watermark, or per-image fee. The practical limit is the memory and Canvas capacity available in your browser, which can be lower on an older phone than on a desktop computer.

What image formats and limits are supported?

The tool accepts PNG, JPEG, and WebP files up to 50 MB. Each image side must be no larger than 16,384 pixels, and the image can contain up to 50 megapixels. You can export PNG, JPEG, or WebP when your browser supports the chosen format.

What block size should I use to pixelate a photo?

Start near 8 to 16 pixels for a clear retro look that keeps the subject recognizable. Use 2 to 4 pixels for fine texture, or 32 to 64 pixels for a strong mosaic. The best value depends on the source dimensions, so compare the live preview rather than relying on one fixed number.

Does pixelating an image reduce its dimensions?

No. The downloaded image keeps the original pixel width and height. Internally, the tool creates a much smaller color grid and scales it back up with nearest-neighbor rendering. The visible blocks become larger, but the exported canvas retains the source dimensions.

Can I use pixelation to hide a face or private text?

Do not rely on pixelation for secure redaction. A coarse mosaic hides detail from casual viewing, but recognizable patterns or short text can sometimes be inferred or reconstructed. For sensitive information, place an opaque solid shape over the content and flatten the image before sharing it.

Which output format should I choose?

Choose PNG for sharp block edges and transparency. JPEG usually creates a smaller photo file, but it cannot keep transparent pixels and may add compression artifacts near color boundaries. WebP can offer small files with transparency in browsers that support its encoder.
