HEIC to BMP converter: free, fast and secure
Need to change an image from HEIC to BMP? This tool does it instantly and for free, without uploading your pictures anywhere. iPhone photos are saved as HEIC, which many Windows PCs, Android apps, websites and government portals cannot open. Converting to BMP makes them work everywhere. Some older Windows software, embroidery machines and industrial printers only accept uncompressed BMP files.
Unlike most converters, ConvertKaro never uploads your images. The conversion happens on your own device, so it is quicker, there are no file limits, and your photos stay private.
How to convert HEIC to BMP in 3 steps
- Add your HEIC files. Tap “Select files” or drag and drop one or more .heic images into the box above. You can also paste a screenshot with Ctrl+V.
- Adjust the options. The default settings work for most images, so you can skip this step.
- Download your BMP. Conversion starts instantly. Download each BMP file, or all of them at once as a ZIP.

What is HEIC?
HEIC is the photo format iPhones and iPads use by default since iOS 11. It stores a photo in about half the space of a JPG with the same quality, which saves a lot of phone storage. Outside the Apple world, though, HEIC is a headache: many Windows PCs, Android apps, websites and government portals cannot open or accept it, so people convert HEIC photos to JPG or PNG before sharing.
What is BMP?
BMP is the classic Windows bitmap format. It stores every pixel without compression, so the quality is perfect but the files are huge: a normal phone photo can become 10–30 MB. Today BMP is mostly used by older Windows programs, embroidery and printing machines, and some industrial software that expects raw pixel data.
When should you convert HEIC to BMP?
- Legacy Windows software
- Embroidery, laser and industrial machines
- Programs that need raw, uncompressed pixels
- Some school and lab software
Tips for the best BMP results
- On iPhone you can also set Settings → Camera → Formats → “Most Compatible” to shoot JPG directly in future.
- If your image has a transparent background, pick a background colour that matches where the image will be used.
- You can convert many HEIC files at once. They are processed one after another and can be downloaded together as a ZIP.
- Keep your original HEIC files until you have checked the converted BMP images.
How HEIC to BMP keeps your photos and images private
When you add a file to HEIC to BMP, it is opened with your browser’s own engine, processed in memory and offered back to you as a download. ConvertKaro never receives a copy. This is why the tool is fast even on 4G, why there is no daily limit, and why it is safe for confidential photos and images like ID proofs, bank documents, contracts and family photos.

Frequently asked questions
Will converting HEIC to BMP reduce quality?
BMP stores the image none, so no extra quality is lost during conversion. Any detail already removed by the original HEIC compression cannot be restored, and the BMP file may be larger than the original.
Does BMP keep transparency from HEIC?
BMP does not support transparency, so transparent areas are filled with a background colour. White is the default, and you can pick any colour before converting.
Can I convert multiple HEIC files to BMP at once?
Yes. Select or drop as many HEIC images as you like. Each one is converted separately, and you can download them all together as a ZIP file.
Why can’t I open HEIC photos on Windows?
Windows needs a paid HEVC extension to read HEIC, and many apps do not support it at all. Converting to JPG or PNG is the simplest fix and works on every device.
Is HEIC to BMP really free?
Yes, completely free. You can use it as many times as you want, and every option on the page is included at no cost.

Yes, the tool is built mobile-first. Open this page on your phone, add your files and download the result directly.
Is there a file size limit in HEIC to BMP?
There is no fixed limit set by us because files are not uploaded. Very large files depend on your device’s memory; most phones handle files of 100 MB or more without problems.

No. There is no watermark, no login and no email required. Your downloaded file is exactly your result.
