How it works

How to convert HEIC to BMP

  1. Add your HEIC files

    Drop HEIC files onto the converter, click to choose them, or paste from the clipboard. Add as many as you like.

  2. Check the settings

    BMP is already selected. Set a maximum width or height if you want smaller images.

  3. Download your BMP images

    Each file gets its own download button as soon as it's ready. Download all saves everything in one ZIP file.

The formats

HEIC and BMP at a glance

  • What is a HEIC file?

    HEIC is the format iPhones and iPads save photos in by default. It stores a photo in about half the space of a JPG at similar quality, and it can hold extras like depth data. Windows, many Android apps, and most websites still struggle to open it, which is why HEIC photos often need converting before you share or upload them. It opens in iPhone, iPad, and Mac (Photos and Preview), Safari, Windows 10 and 11 with Microsoft's HEIF and HEVC extensions, and recent Android phones. Most other browsers and upload forms can't open it.

  • What is a BMP file?

    BMP is the uncompressed bitmap format from early versions of Windows. It stores every pixel as is, so quality is perfect but files are large, often ten times the size of a PNG. Today it's mostly needed by older software, embedded devices, and some printers and label makers. It opens in Windows Paint and Photos, macOS Preview, browsers, and nearly every image editor.

Good to know

What changes when you convert HEIC to BMP

  • BMP is lossless, so the image won't lose any more quality, but it can't restore detail that HEIC compression already removed. Expect a bigger file.
  • Live Photos and bursts convert as a single still photo, and HDR photos are converted to standard range.
  • BMP files are saved uncompressed, so they're large but lossless.
  • Metadata such as the camera model, date, and GPS location isn't copied to the new file, so you don't share your location by accident.
  • Very large images, around 100 megapixels or more, can exceed what the browser allows, especially on phones.

FAQ

Questions, answered

Is this HEIC to BMP converter free?

Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.

Are my files uploaded anywhere?

No. The conversion runs inside your browser with the browser's built-in image codecs plus small WebAssembly encoders, so your files never leave your device. Once the page has loaded, it even works offline.

Does converting HEIC to BMP lose quality?

No. BMP is lossless, so the converted image has exactly the pixels of the HEIC. It can't undo compression that the HEIC already has, though, and the file may be bigger.

Can I stop my iPhone from saving HEIC photos?

Yes. Open Settings, tap Camera, then Formats, and choose Most Compatible. New photos are then saved as JPG, and videos as H.264. Photos you already took stay HEIC, so convert those here.

Can I convert several HEIC files at once?

Yes. Add as many as you like. They're converted one after another, and you can download each BMP file as soon as it's ready or all of them in one ZIP file.

Does it work on iPhone, Android, Mac, and Windows?

Yes. It works in Chrome, Edge, Firefox, and Safari, on computers, iPhones, and Android phones.

What can open a BMP file?

Windows Paint and Photos, macOS Preview, browsers, and nearly every image editor.

Is there a file size limit?

There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle images up to about 100 megapixels.
