About the AVIF to BMP Converter
Convert AVIF to BMP online for free, with no account and no watermark. Older software and some upload forms do not accept AVIF yet, so switching to BMP is the quickest way to get a raw bitmap for legacy software for legacy Windows software, embedded displays, machine vision and printing tools that need raw pixels.
The converter decodes your AVIF 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 AVIF to BMP Converter
- Click "Choose files" or drag your AVIF 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 AVIF 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.
- Converting a compressed AVIF to BMP will not bring back detail that was already discarded; it simply prevents further loss when you edit.
- 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 AVIF to BMP?
Click "Choose files", select your AVIF 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 AVIF 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 AVIF to BMP reduce the quality?
No. BMP stores the image without lossy compression, so the result looks exactly like your AVIF, except that transparent areas get a solid background.
Can I convert several AVIF files at once?
Yes. Add as many AVIF 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 AVIF and BMP?
AVIF (AV1 Image File Format) is a next-generation web image best suited to the smallest possible website images and Core Web Vitals optimisation. 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.
Can I convert AVIF to BMP under a size limit such as 50 KB?
Yes. Lower the quality slider and set a maximum width (for example 800 px) to shrink the file. For an exact limit, run the result through our Compress Image to 20 KB, 50 KB or 100 KB tools, which find the best quality that fits automatically.
AVIF ko BMP kaise kare?

What is a AVIF file?
AVIF is a royalty-free image format built on the AV1 video codec and released in 2019. It is often 30–50% smaller than JPG at the same visual quality and supports transparency and HDR, making it the most efficient image format browsers support today.
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.
