How to convert PNG to ICO

  1. Drop your PNG images on the box above, or choose them. One image or a whole folder of them.
  2. Pick the sizes: a website favicon (16, 32 and 48 px) or a Windows and app icon (16 to 256 px).
  3. Each image converts on this device straight away, with its old and new size next to it.
  4. Download one file free, or a whole batch as one ZIP with a Day Pass or Unlimited.

What is kept, and what changes

DetailIn your ICONotes
Size in pixelsSquares of 16, 32 and 48 px, or up to 256Every size in the icon is a square. A picture that isn't square is fitted inside, centred, with see-through space around it.
TransparencyKeptSee-through areas stay see-through.
QualitySharp at every sizeEach size is shrunk from your picture in steps, then stored lossless (a PNG inside the icon).
Photo details (EXIF)RemovedCamera, date and location details are not copied into the new file, so it is safe to share.
ColoursKept, in standard sRGBWide-colour and HDR pictures are converted to standard colour, which every screen and app shows the same way.

Problems and fixes

The icon looks blurry at 16 px
A 16 px icon has room for very little detail. A simple, bold mark works best: convert a version of your logo without small text or thin lines.
My site still shows the old favicon
Browsers keep favicons for a long time. Put favicon.ico in the top folder of your website, then check in a private window or after clearing the browser cache.
"FileInto couldn't read this image"
The file may be damaged, or not really a PNG. Open it in your photo app; if it shows there, save a fresh copy and try again.
It is slow with hundreds of photos
Large batches use every core of your device but still take a moment per photo. Keep the tab open; the images convert a few at a time and the ZIP is built at the end.

Questions

How do I convert PNG to ICO?
Drop your PNG images on the converter on this page. They convert in your browser straight away; download one ICO, or all of them as a ZIP. No sign-up and no upload.
Is this PNG to ICO converter free?
Yes, one image at a time, with no account and no sign-up. Converting many images at once, with one ZIP to download, needs a Day Pass ($7 for 24 hours) or Unlimited.
Are my images uploaded anywhere?
No. Your browser decodes and re-encodes each image inside this tab. Your file never reaches our servers, and nothing about it does either: not its name, its size or how many rows it has.
Why convert PNG to ICO?
PNG is lossless and keeps transparency, which makes it right for screenshots, logos and graphics, but large for photos. ICO is the safer choice for website favicons and Windows icons.
Can I convert many images at once?
Yes, with a Day Pass or Unlimited. Drop as many as you like, or a whole selection from a folder. They convert a few at a time on your device and download together as one ZIP. Free converts one image at a time.
Does it work on iPhone and Android?
Yes, in current Safari, Chrome, Edge and Firefox, on phones and computers. On a phone, choose the images from Photos or Files.
What are the limits?
Images up to 50 MB each. Free converts one image at a time, no account needed. Converting many at once, with one ZIP to download, needs a Day Pass ($7 for 24 hours) or Unlimited ($9 a month). It works in current versions of Chrome, Edge, Safari and Firefox, on computers and phones.
How do I use the ICO as my website's favicon?
Name it favicon.ico and put it in the top folder of your website. Browsers look for it there on their own. You can also point to it from every page with a link tag: rel set to icon and href set to /favicon.ico.
