Image Pixelator
Upload a photo and adjust the pixel size and color levels to turn it into pixel-art style graphics. Everything runs in your browser, so images never leave your device.
How to use
- Drag in or click to upload the photo to convert.
- Adjust pixel size, palette color count, dithering, and the centered crop area.
- Check the original and result with the before/after slider and reuse style presets.
- Choose the original area size or an integer scale, then save with "Download PNG".
Frequently asked questions
What is pixel size?
It is the size of each dot (pixel block). Larger values make bigger dots and a stronger pixel-art look.
What are color levels?
It reduces the number of color steps to create a retro game graphics feel. Fewer levels means simpler colors.
Are uploaded photos sent to a server?
No. All conversion happens on a canvas in your browser; images are never sent to an external server.
Practical example and verification criteria
Image Pixelator: First decide the source resolution, target grid or block size, palette, transparent background, and final display scale. Pixelation irreversibly simplifies a large image, so test each setting again from the source. For small pixel art, check whether nearest-neighbor scaling is more appropriate than smooth interpolation.
Image Pixelator: For a quick check, start with 320×320 / block 16 → 20×20 blocks as a small input whose result relationship you can verify directly. Confirm that the input summary, units, and options match your intent before applying the tool to real values or a copy of the source; this reduces setup mistakes.
Image Pixelator: At 100% and the real publishing scale, inspect broken outlines, unintended semitransparent pixels, and color bleeding, then reopen the exported file to compare its size and transparency. Large canvases consume browser memory and simple upscaling creates no new detail, so preserve the project file and source separately.
Image Pixelator · Work record: For real work, record the input conditions, selected options, and result together. Do not assume the same state will remain after a refresh or device change. Preserve important results separately using copy, download, a screenshot, or another method the page supports, then reopen them in the target environment.
Image Pixelator · Error check: If an error or unexpected result appears, reduce the input, run again with default options, and then change one condition at a time. Recording error messages and boundary values helps distinguish format issues, unsupported cases, and browser resource limits, and prevents an empty result from being mistaken for success.
Image Pixelator · Scope of use: Check the page guidance for browser processing versus server lookup, storage location, and supported scope. Use sensitive source material or secrets only when strictly necessary. High-impact work such as legal, financial, or medical decisions or changes to an operational system requires current authoritative information and a separate verification process.
