HEIC to BMP Converter

How to Convert HEIC to BMP Online

1. Upload Your HEIC Files: Drag and drop or click "Add Files" to select one or more HEIC photos from your iPhone, iPad, or Mac. Batch is supported, so you can queue dozens of Live Photo stills or AirDrop exports at once.
2. Pick a Quality Preset: The Quality preset dropdown defaults to Very High (Recommended). Choose Highest for archival output, Medium or Low when you only need a quick on-screen reference, or Lowest to keep the BMP small. Because BMP itself is uncompressed, the preset mainly governs the JPEG-style quality of the decoded HEIC pixels written into the bitmap.
3. Set Resolution Percentage or Preset (Optional): Keep original to preserve every pixel. Otherwise scale by Resolution Percentage (1-100%), pick a Preset Resolution from 4320p down to 144p, or enter exact values via Width (Keep aspect ratio), Height (Keep aspect ratio), or Width x Height. Downscaling matters here — 24-bit BMP stores about 3 bytes per pixel uncompressed, so a full 48 MP iPhone shot can balloon past 140 MB at native size.
4. Convert and Download: Click Convert. Files render on our servers — no sign-up, no watermark, and your photos is deleted from our servers after one hour.

Why Convert HEIC to BMP?

HEIC is the .heic variant of HEIF, the High Efficiency Image File Format Apple adopted as the default iPhone capture format in iOS 11 (2017). HEIC wraps HEVC-encoded image data and routinely halves the file size of an equivalent JPEG. BMP — Microsoft's device-independent bitmap, in use since the Windows 2.x / OS/2 1.x era — is the opposite philosophy: store every pixel, no compression, no codec dependencies. Converting HEIC to BMP gives you a file that any Windows tool, scientific imaging pipeline, or embedded system can read without a HEVC decoder.

• Windows machines without the HEVC extension — On Windows 10 and 11, opening a HEIC needs both the free HEIF Image Extensions and a separate HEVC Video Extensions package (the consumer version is $0.99 in the Microsoft Store because of HEVC royalty obligations). BMP has no such dependency.
• Legacy and industrial software — Older Delphi/MFC apps, machine-vision SDKs, GIS tools, label printers, and embedded GUI frameworks frequently accept BMP as the only photographic input. They were written before HEIF/HEIC existed.
• Pixel-exact editing pipelines — Because BMP carries no lossy compression, every save round-trip is bit-identical. Useful for photo restoration, forensic work, or any workflow where you don't want a re-encoder touching the data after the initial HEIC decode.
• Print-shop and signage RIPs — Some raster image processors and large-format plotters still ingest 24-bit BMP more reliably than newer formats, especially for proofing.
• Game and 3D-engine asset pipelines — Engines that read raw bitmaps for textures, sprite sheets, or splash screens often want a flat, header-light BMP rather than a HEIF container.
• Microsoft Paint, Office clipart, and screenshot tooling — Plain BMP drops straight into Word, PowerPoint, and classic Paint with no codec install on locked-down corporate desktops.

HEIC vs BMP — Format Comparison

BMP Bit Depth and Compression Quick Guide

Pick the right BMP variant for the downstream tool. Most conversions land on 24-bit uncompressed because that is the lingua franca, but indexed modes can shrink the file dramatically when colors are limited.

Photographs decoded from HEIC almost always want 24-bit; reaching for 8-bit indexed on a continuous-tone photo will introduce visible banding.

Frequently Asked Questions

Why is my BMP roughly 20x larger than the original HEIC?

That is expected and correct. HEIC compresses with HEVC (a modern lossy video codec) and a 12 MP iPhone photo lands around 1.5-3 MB. BMP at 24-bit stores three full bytes per pixel uncompressed, so the same 12 MP image becomes ~36 MB. If size matters, downscale with the Resolution Percentage option, or pick HEIC to JPG or HEIC to PNG instead.

Will I lose quality going from HEIC to BMP?

Not from the BMP step itself — BMP is uncompressed, so the encoder is not throwing pixels away. Whatever quality survived the original HEIC encode in your camera is what gets written. The Quality preset only affects how the HEIC is decoded and re-quantized into the 8-bit-per-channel BMP color space; Highest or Very High is fine for almost every use.

Do iPhone Live Photos convert correctly?

The still image inside a Live Photo (the .heic keyframe) converts cleanly. The motion clip portion is HEVC video stored alongside the HEIC and is not part of a still-image conversion. If you want the motion, export it from the Photos app as a video first.

Will the BMP keep my EXIF data, location, and timestamps?

Classic BMP headers do not include rich EXIF blocks. We write a standard Windows DIB so capture date, GPS coordinates, lens info, and camera model are not embedded the way they are in JPG or HEIC. If you need EXIF, prefer HEIC to JPG or HEIC to TIFF.

What bit depth does the output BMP use?

Photos decoded from HEIC are written as 24-bit RGB by default, which is the variant every Windows tool understands. iPhones can capture HEIC at 10-bit per channel; that extra dynamic range is collapsed to 8-bit per channel during BMP encoding because BMP itself is overwhelmingly an 8-bit-per-channel format in practice.

Why won't Windows open the HEIC directly so I don't have to convert?

Windows 10 and 11 can read HEIC, but only after you install two store packages: HEIF Image Extensions (free) and HEVC Video Extensions (Microsoft charges $0.99 for the consumer version because they pay HEVC royalty fees). On a locked-down work PC where you cannot install Store apps, BMP is the simplest universal target.

Can I batch-convert hundreds of HEIC photos at once?

Yes. Add the entire shoot, set the Quality preset and Resolution Percentage once, and the tool processes the queue in your browser. Because BMP files are large, watch your free disk space — 200 full-resolution iPhone photos can produce ~7 GB of BMP output.

Should I use BMP or PNG for lossless Windows compatibility?

PNG is also lossless and is roughly a third the size of an equivalent BMP because it uses DEFLATE compression. Modern Windows, Office, and every browser open PNG natively. Choose BMP only when the downstream tool specifically asks for it; otherwise HEIC to PNG is the better default. For a Windows-friendly photo at small size, HEIC to JPG wins on every metric except being lossless.

Are my photos uploaded to a server?

No. The Conversion runs on our servers, files are processed on our servers, and nothing is retained after you close the tab. There is no sign-up, no watermark, and no daily quota for the free tier on this conversion.
