Free PNG to BMP converter

Why convert PNG to BMP?

People convert PNG to BMP because PNG keeps every pixel exactly, which makes photographs several times larger than they need to be, while BMP is the plainest possible bitmap, which old software and hardware accept without complaint.

How to convert PNG to BMP

1. Choose your PNG file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .bmp. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .png file?

PNG is lossless: it stores every pixel exactly as it was, and supports a transparent background. It is the right format for screenshots, logos, diagrams, icons and anything with sharp edges or text. Photographs come out noticeably larger than they would as JPG.

What is a .bmp file?

BMP stores pixels uncompressed, which makes files very large and very simple. It survives from early Windows and still appears in older software and some hardware exports; almost any modern format will store the same picture in a fraction of the space.

What to expect from this conversion

The target format is lossless, so every pixel of the decoded image is preserved exactly. The result can be larger than the original, which is the normal trade for keeping full quality. BMP is uncompressed, so expect the result to be considerably larger than the original.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your PNG file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.

Questions about PNG to BMP

Is this PNG to BMP converter free?

Yes, completely. There is no account, no daily limit, no watermark and no premium tier.

Is my PNG file uploaded to a server?

No. The conversion runs inside your own browser using your device's processor. The file is read from your disk, converted in memory and saved back to your disk — nothing is transmitted, so there is nothing for anyone to store.

Can I convert PNG to BMP online without downloading software?

Yes. This is an online PNG to BMP converter that runs in your browser, so there is nothing to install and no app to trust with your files. It works the same on a phone.

What happens to the quality?

The target format is lossless, so every pixel of the decoded image is preserved exactly. The result can be larger than the original, which is the normal trade for keeping full quality. BMP is uncompressed, so expect the result to be considerably larger than the original.

Does PNG to BMP keep a transparent background?

No. BMP cannot store transparency, so any transparent area is flattened onto a solid colour — white unless you choose another. Pick PNG or WebP as the target if the transparency matters.

How do I convert PNG to BMP on Windows, Mac or Linux?

The same way on all three: open this page in Chrome, Edge, Firefox or Safari, drop the PNG file, press Convert and download the BMP. Nothing is installed and no admin permission is needed.

Can I convert several PNG files at once?

Yes. Select as many files as you like and they are converted one after another in a single tap, with a download for each and a zip of all of them.

Should I keep the original PNG file?

Yes — keep it, converting never touches it. The reason to make a copy in another format is that PNG keeps every pixel exactly, which makes photographs several times larger than they need to be.
