How to convert PNG to BMP

The PNG is decoded on your device and re-encoded as BMP with the browser's own graphics engine. Because nothing is uploaded, even dozens of photos convert quickly and privately. BMP stores uncompressed pixels, which some legacy and industrial software still requires.

Step 1: Choose your PNG file
Drag and drop a .png file onto the converter or click to browse. It works on desktop, tablet and phone.
Step 2: Convert to BMP
Each image is converted to BMP immediately.
Step 3: Download the BMP
Save each result individually, or download everything as a single ZIP when you convert several files.

Good to know

BMP has no transparency, so transparent areas are filled with white.
Photo metadata (EXIF, GPS location) is removed from the converted image, which is good for privacy.

Why use this PNG to BMP converter?

Batch conversion: drop several images at once and download a ZIP.
Nothing is uploaded, so personal photos stay private.
Original resolution is kept.
No watermark, no account, no app to install.

Is it free?

Yes. Converting PNG to BMP is free, with no watermark, signup or email required. Local conversions have no artificial file-size or daily cap; the practical limit is your device.

Is my file uploaded?

The PNG file is processed entirely in your browser. It is never uploaded, never stored and never seen by anyone, so this is safe for confidential files.

About the formats

What is PNG?

PNG (Portable Network Graphics) is a lossless image format created in the mid-1990s as an open replacement for GIF. It keeps every pixel exactly as it was and supports an alpha channel, so images can have smooth, partial transparency. Photos saved as PNG are much larger than the same photos as JPG.

Use PNG for logos, icons, screenshots, diagrams and any image with sharp edges, text or a transparent background. For photographs where file size matters, JPG or WebP are usually better choices.

What is BMP?

BMP, also called DIB (device-independent bitmap), is a raster image format that Microsoft introduced with Windows. It usually stores every pixel uncompressed, so image quality is untouched but files are very large. The format is simple and widely readable, yet it offers little that PNG does not do better.

Use BMP only when an old program, a device or an embedded system specifically requires it. For everyday use, convert BMP files to PNG to keep the same quality at a fraction of the size, or to JPG for photos.
