Setup: HEIC is Apple's HEVC-based photo container, half the size of JPEG for the same apparent quality. Goal: an interchangeable BMP. Need a BMP for a CMS, a chat message or an email client that politely refuses HEIC? This tool re-encodes your image in the background and returns a drop-in BMP replacement. No registration, no watermark, no visual change beyond what the BMP encoder itself introduces. Keep in mind HEIC is Apple's HEVC-based photo container, half the size of JPEG for the same apparent quality. And remember that BMP is the uncompressed Windows bitmap format — bulky but pixel-perfect.
HEIC Image
Source formatHEIC is the default photo format on Apple devices since iOS 11. It offers roughly 50% better compression than JPEG at similar quality but has limited support outside the Apple ecosystem.
BMP Image
Target formatBMP is an uncompressed raster image format native to Windows. Files are large but preserve exact pixel data with no compression artifacts. Rarely used on the web due to file size.
Why convert HEIC to BMP
Converting keeps the picture recognisable end-to-end while changing the container that ships it. BMP typically wins on one of three fronts: broader software support, smaller files for the same visual quality, or features like transparency that HEIC cannot express. The conversion itself is fast because both sides are raster formats.
HOW TO CONVERT
HEIC → BMP
Upload your HEIC
Start by dropping the HEIC onto the uploader. Files up to 100 MB go through on the free tier without registration.
Conversion happens server-side
Our imagemagick-based pipeline reads the HEIC pixel grid, preserves resolution and colour profile, and encodes a clean BMP.

Common Use Cases
Cross-platform previews
Windows, macOS and Linux file browsers all render BMP thumbnails; HEIC support varies by OS version.
Mobile galleries
iOS Photos, Google Photos and Samsung Gallery index BMP instantly — HEIC sometimes falls back to a generic file icon.
Stock photography uploads
Shutterstock, Adobe Stock and similar marketplaces require BMP in their contributor guidelines.
Archive migration
Converting legacy HEIC archives to BMP future-proofs the collection against declining codec support.
Quality & Compatibility
Converting keeps resolution, aspect ratio and colour profile identical to the source. Metadata (EXIF, XMP) transfers where BMP supports it; otherwise it is dropped. If the HEIC contained an alpha channel and BMP does not support transparency, the background is flattened to white by default.
Tips for Best Results
- When uploading to Retina / high-DPI contexts, render the BMP at 2× the CSS pixel size; the crispness gap over 1× is noticeable on modern screens.
- Strip EXIF metadata from the BMP before publishing if the HEIC came from a phone camera — it often contains GPS coordinates and device IDs.
- If the HEIC is a screenshot of text or UI, prefer a lossless BMP target to avoid the JPEG-style ringing around glyph edges.
Frequently Asked Questions
Frequently Asked Questions
It depends on the codecs involved. If both HEIC and BMP are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If BMP is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded HEIC exactly, but cannot recover detail that HEIC had already compressed away.
Often yes, especially when BMP is lossless. HEIC tuned for efficient web delivery will usually produce smaller files than BMP's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
