Why convert BMP to PNG?
PNG keeps BMP images pixel perfect while making the files much smaller, since PNG uses lossless compression.

About the formats
What is BMP?
BMP is the classic Windows bitmap format. Images are usually stored without compression, so files are very large: a 12 megapixel photo takes around 36 MB as a 24 bit BMP.
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.
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.
Is the BMP to PNG 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.
