About formats

HEIC

HEIC (High Efficiency Image Container) is Apple's implementation of the HEIF standard, using the HEVC codec. It stores images at roughly half the file size of JPEG at comparable quality. HEIC is the default photo format on iOS 11+ and macOS High Sierra+, and supports multiple images and depth data within a single file.

Developer: Apple / MPEG
Initial release: 2017
Compression: Lossy
Color depth: up to 16-bit HDR
Transparency: Yes
Animation: Yes

Best for

Saving iPhone photos
High-quality mobile photography
Reducing photo storage on iOS
HDR image capture
Efficient photo archival on Apple devices

Pros

+Roughly half the size of JPEG at comparable quality
+Supports transparency and animation
+Stores multiple images and depth data
+Default iOS photo format

Cons

−Limited support on older Windows and non-Apple platforms
−Requires newer software to decode
−Less universally supported than JPG
−No universal web browser support historically

BMP

BMP (Bitmap) is a simple, largely uncompressed raster image format native to Windows. BMP stores pixel data with optional Run-Length Encoding, making it trivial to read and write, but produces very large files. It remains useful as an intermediate, loss-free working format.

Developer: Microsoft
Initial release: 1985
Compression: Uncompressed
Color depth: up to 32-bit
Transparency: Yes
Animation: No

Best for

Lossless intermediate image storage
Windows-native graphics workflows
Simple pixel-data interchange
Uncompressed image working copies
Legacy Windows application images

Pros

+Trivial to read and write
+Lossless and uncompressed
+Supports up to 32-bit color
+No decoding complexity

Cons

−Very large file sizes
−No compression by default
−Not suited for web
−No modern features like animation

Frequently Asked Questions

Is converting HEIC to BMP free?

Yes. This HEIC → BMP converter runs entirely in your browser and is completely free — no account, no credits, no watermark.

Which devices and platforms can I use to convert HEIC to BMP?

Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.

Are my HEIC files uploaded to a server?

No. Files never leave your device. The entire HEIC → BMP conversion runs locally in your browser, so your data stays private.

Can I convert multiple HEIC files at once?

Yes — batch conversion is supported. Add as many HEIC files as you like and convert them to BMP in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.

Will converting HEIC to BMP lose quality?

No. BMP is a lossless format (or used in a lossless mode here), so the original data from your HEIC file is preserved bit-for-bit in the converted result.

Will transparency be preserved when converting HEIC to BMP?

Yes. Both HEIC and BMP support alpha-channel transparency, so transparent areas of your file are kept unchanged in the BMP output.

How will the file size change after converting HEIC to BMP?

Both formats use comparable compression, so the BMP output will be similar in size to your HEIC file — typically within 10–20% of each other.
