About the formats
What is PNG?
PNG is a lossless image format released in 1996. Every pixel is kept exactly, and it supports full transparency, which makes it the usual choice for logos, icons, screenshots and anything with text. Photos saved as PNG are often several times larger than the same photo as JPG.
What is ICO?
ICO is the Windows icon format. One ICO file can hold the same icon in several sizes, so the system or browser can pick the sharpest one. ConvertOrino creates ICO files with 16, 32, 48, 64, 128 and 256 pixel versions inside.
Questions
Questions and answers
Is it safe to convert my files here?
Yes. ConvertOrino converts your files with code that runs in your own browser. Nothing is uploaded to a server, nobody else can see your files, and they are gone as soon as you close the page.
How do I add the ICO as a favicon to my website?
Upload the file to the root of your site as favicon.ico. Browsers look for it there automatically. You can also link it in the page head with a link tag where rel is icon.
What image should I start from?
A square PNG of at least 256 by 256 pixels with a transparent background gives the best result. Non square images are centered on a transparent square.
Is the PNG to ICO tool free?
Yes, completely free. There is no sign up, no watermark and no limit on the number of files.
Is there a file size limit?
There is no fixed limit, because your own device does the work. Very large files are limited by the memory of your device. Phones handle files of a few hundred megabytes, computers handle much more.
Does it work on iPhone, Android, Mac and Windows?
Yes. It works in any modern browser, including Safari, Chrome, Edge and Firefox, on phones, tablets and computers. Nothing needs to be installed.
Is hidden metadata such as location removed?
Yes, by default. Location, camera details and other EXIF data are removed from every converted image. For JPG output you can untick Remove metadata to keep the date taken and camera details instead.
Does it work offline?
Yes. Once the page has loaded, the conversion works without an internet connection, which also proves that your files are not sent anywhere.
