Quick answer: To convert PNG to ICO, add the PNG file to the iHateFiles PNG to ICO converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. Turns artwork into a Windows icon or a favicon, written at every size a browser asks for.
Should you convert PNG to ICO?
A safe conversion: PNG and ICO are both lossless, so this is a change of container rather than a change to the picture.
Nothing is discarded
PNG and ICO are both lossless, so every pixel survives the move intact. Convert back and forth as often as you like; the image does not degrade.

What usually goes wrong
About the PNG. People save photographs as PNG and wonder why an email bounces. A photo that is 400 KB as a JPG is routinely 4 MB as a PNG, because lossless compression cannot do much with the noise in a real photograph.
About the ICO. Renaming a PNG to favicon.ico works in most browsers and then fails in the one that matters. A real ICO bundle avoids the argument entirely.
How to convert PNG to ICO
- Add your PNG file. It is read from your disk and stays there.
- Check the settings. The output format is already set to ICO.
- Press convert and the ICO file is saved back to your device.
Questions
How do I convert PNG to ICO?
Open this page, add your PNG file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this PNG to ICO converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to ICO lose quality?
ICO is lossless, so this step throws nothing away. If the original was already a lossy format, the damage it did cannot be undone, but nothing further is lost.
Can I convert several PNG files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
