Convert ICO to PNG — free, private, in your browser
Decoded with browser decoder, encoded with OxiPNG — entirely on your device. No upload, no queue, no watermark.
Why convert ICO to PNG?
Convert ICO (the favicon and windows icon container format) to PNG — the conversion can preserve every pixel, and transparency carries over. Drop files below: decoding and encoding run entirely in your browser via WebAssembly, so images are never uploaded to a server.
How to convert ICO to PNG
- 1Drop your ICO files onto the tool above (or click to browse, or paste from the clipboard). Batches are fine.
- 2PNG is pre-selected as the output. PNG is lossless, so there is no quality to lose. Optionally cap the maximum dimension to also downscale.
- 3Each file converts in your browser and shows its new size. Download files individually or grab everything as a ZIP.

Frequently asked questions
Is it safe to convert ICO to PNG online?+
With EditItAll, your files are never uploaded: decoding and encoding run inside your browser using WebAssembly (the browser's built-in decoder to decode, Squoosh-grade codecs (MozJPEG, libwebp, libavif, libjxl, OxiPNG) to encode). The images stay on your device from start to finish, and the whole thing works offline once the page has loaded.
Will converting ICO to PNG lose quality?+
No. PNG is lossless: every pixel of the decoded ICO is preserved exactly.
Is there a file size or count limit?+
No hard limits and no accounts — processing uses your own device's memory and CPU, so very large images are only constrained by your browser (multi-hundred-megapixel images may fail on low-memory devices). Batch as many files as you like; they are processed in sequence.
Can I convert PNG back to ICO?+
Yes — use the PNG to ICO converter, or just change the output format dropdown after dropping files.
