Format descriptions
PNG — PNG is a lossless raster format that supports transparency. It is ideal for logos, graphics and screenshots because it never loses quality, although files can be larger.
BMP — BMP is a lossless raster image format developed by Microsoft. It delivers perfect quality but produces very large files.

What happens when converting PNG to BMP?
The PNG data is decoded inside your browser with WebAssembly and re-encoded to the BMP specification, so no file is ever uploaded to a server. Both formats rely on comparable compression, so file size and perceived quality stay in the same range. BMP has no alpha channel, so transparent areas of PNG are flattened onto a solid background colour.
Frequently Asked Questions
What is image conversion?
Image conversion changes an image file from one format to another, for example from PNG to BMP, while keeping the image content.
Are my images uploaded?
No. This tool processes images directly in your browser. Your images are never sent to a server.
Which image formats are supported?
This tool converts PNG images to BMP, all in your browser.
Is it really free and unlimited?
Yes, the tool is completely free and you can convert as many images as you want, with no limits.
Does it work on mobile too?
Yes, it works on any modern device, including smartphones, tablets and desktop computers.
Which format will the result be in?
The converted image will always be in BMP format, ready to download and use.
What happens to transparency when converting to JPG?
JPG does not support transparency. If your image has an alpha channel (for example a PNG or WebP with a transparent background) and you convert it to JPG, the transparent areas are flattened and may appear with a dark or black background. Use PNG, WebP, TIFF or GIF output to preserve transparency.
