About the PNG to BMP Converter
This PNG to BMP converter turns images from PNG into BMP without installing software or uploading anything. It solves a common problem: PNG photos are large and slow to upload or email. Converting to BMP gives you a raw bitmap for legacy software, ideal for legacy Windows software, embedded displays, machine vision and printing tools that need raw pixels.
The converter decodes your PNG with your browser's own image engine and writes the BMP with a small open-source BMP encoder, so quality settings are applied precisely. Because everything happens on your own device, your images are never uploaded, stored or seen by anyone else, which makes it safe for ID photos, Aadhaar or PAN scans and personal pictures.
What to expect: BMP cannot store transparency, so transparent areas are filled with a background colour you pick (white by default); BMP stores the pixels without further quality loss; camera metadata such as GPS location is removed because the image is re-encoded.
How to use the PNG to BMP Converter
- Click "Choose files" or drag your PNG images onto the box. You can add several at once.
- Pick the background colour for transparent areas and, if you like, a maximum width.
- Press "Convert to BMP". The conversion runs on your device and shows its progress.
- Download each BMP file, or use "Download all (ZIP)" when you converted several.
- Open the result in Windows Paint or Windows Photos to check it; your original PNG is never changed.
Tips & benchmarks
- BMP files are uncompressed and large (a 12 MP photo is about 36 MB); transparent areas are flattened onto white.
- Password-protected (encrypted) archives cannot be converted; extract them with the password first.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the BMP to a website or government portal.
Frequently asked questions
How do I convert PNG to BMP?
Click "Choose files", select your PNG images, adjust the options if you want, and press "Convert to BMP". The BMP downloads immediately; with several files you can download everything as one ZIP.
Is this PNG to BMP converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your images never leave your phone or computer and nothing is stored on News Appite's servers.
Will converting PNG to BMP reduce the quality?
No. BMP stores the image without lossy compression, so the result looks exactly like your PNG, except that transparent areas get a solid background.
Can I convert several PNG files at once?
Yes. Add as many PNG files as you like; they are converted one after another and you can download them individually or together as a ZIP.
Does it work on iPhone, Android and Mac?
Yes. The converter works in any modern browser, including Chrome, Safari, Edge and Firefox, on Android, iPhone, iPad, Windows, macOS and Linux. No app is needed.
What is the difference between PNG and BMP?
PNG (Portable Network Graphics) is a lossless raster image best suited to screenshots, logos, icons, charts and any image that needs a transparent background. BMP (Windows Bitmap) is a uncompressed raster image best suited to legacy Windows software, embedded displays, machine vision and printing tools that need raw pixels.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
How do I convert PNG to BMP without losing quality?
BMP is lossless, so the converter keeps every pixel of your PNG; just leave the maximum width empty to keep the original size.
Does PNG to BMP keep a transparent background?
No. BMP cannot store transparency, so transparent areas are filled with a background colour you choose (white by default). Convert to PNG or WebP if you need to keep transparency.

What is a PNG file?
PNG was designed in 1996 as a patent-free replacement for GIF. It stores every pixel exactly, supports millions of colours and full alpha transparency, which is why screenshots, logos and interface graphics are usually PNG files.
What is a BMP file?
BMP is the classic Windows bitmap format. It stores raw pixel data with little or no compression, so files are large, but almost every old program, embedded device and industrial machine can read it.
