People preparing logos, interface graphics, stickers, flat illustrations, and transparent assets that can tolerate a smaller indexed palette
Creating a smaller indexed PNG export when the artwork is still visually acceptable with fewer colors
Capture PNG-8 and indexed-PNG intent with a focused browser-first quantization workflow that is separate from general compression
Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To convert a PNG to PNG-8, load the image into the quantizer and choose how many colors the indexed palette should hold. The tool reduces the artwork to that palette and shows you the result so you can judge the visual tradeoff before downloading.
Because indexed PNG is a different decision from ordinary compression, the quantizer lets you preview the palette reduction clearly across multiple backgrounds. When fewer colors are acceptable for the asset, you download a smaller indexed PNG; if not, you can keep the original.
All quantization and export happen locally in your browser, so the PNG stays on your device and nothing is sent to a server.
PNG-8 works best for logos, icons, simple illustrations, transparent stickers, and other graphics that do not need photo-like color depth. For these assets, reducing to an indexed palette can cut file size significantly with little or no visible loss.
It is less suited to photographs and complex gradients, where a limited palette can introduce banding. The tool makes the difference easy to see by letting you preview the indexed result before you commit to the export.
Short answers for the questions people usually have before trying a utility like this.
Yes. This PNG-8 quantizer is free and runs entirely in your browser, with no account or installation needed.
Not always, but it often becomes much smaller when the artwork uses a limited number of colors or simpler transparency.
Yes. The quantizer exports an indexed PNG that keeps transparency where the reduced palette allows it.
No. Quantization and export happen locally in your browser, so the file never leaves your device.
Yes. The quantizer runs in any modern browser, including mobile, since all processing is done on your device.
Every tool on Cleanor is free with no sign-up, no credits, and no limits. Files are processed privately in your browser. Looking for on-device phone cleanup and Premium features? That lives in the Cleanor app.
Reduce the palette, rebuild the PNG as an indexed export, and preview the result on different backgrounds before you download it.
