About PNG
PNG (Portable Network Graphics) is a lossless image format created in 1996 as a free replacement for GIF. It supports full colour and an alpha channel for transparency.
Screenshots, logos, icons, diagrams and any image with text or sharp edges.
For photos a PNG is several times larger than a JPEG, and plain PNG has no animation (that is APNG).
Convert PNG to BMP online free, no account required — BMP is the Windows bitmap format, usually uncompressed.
Change PNG to BMP without losing quality — convert PNG to BMP free in your browser.
Why is my PNG so much bigger than the same photo as JPG? PNG stores every pixel losslessly, which is ideal for screenshots and graphics but wasteful for photos — JPG or WebP compress photographs far more efficiently.
About BMP
BMP is the device-independent bitmap format of Windows. It usually stores every pixel uncompressed.
Legacy Windows software, simple paint programs and embedded systems.
Without compression a BMP is many times larger than a PNG of the same image.
Why convert an image to BMP? Rarely on purpose: only legacy Windows software and some industrial tools expect uncompressed bitmaps.
What changes when you convert PNG to BMP
- PNG and BMP both store pixels without loss, so the picture carries over pixel for pixel.
Settings you can change
Before you convert PNG to BMP, you can adjust: Width, Height, Scale fit, Crop position, Never enlarge, Quality, Lossless, Progressive, Remove metadata, Auto-orient from EXIF, Rotate, and Background.
Limits
Each plan sets a maximum file size and a number of conversions per day, and video and audio files also have a maximum length. Guests can convert files up to 100 megabytes and 5 per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes.
Your converted BMP file is kept for 2 hours, then deleted.
