Choose the output format from the dropdown. Set quality and other options from the Settings panel.
Hit Convert All to batch-process all files at once. Up to 3 files convert in parallel so large queues finish fast.
Download files individually or grab them all as a ZIP. Everything runs in your browser — no uploads to any server.
Convert iPhone HEIC photos to BMP (Bitmap) format for use in Windows applications, legacy software, and workflows that require uncompressed pixel data. BMP stores every pixel without compression, making it the right choice when downstream software cannot handle compressed formats. Free, no upload, processed in your browser.
Uncompressed pixel data for demanding workflows
Maximum compatibility for legacy workflows
Specialized conversion optimised for HEIC → BMP with correct color handling
Convert multiple HEIC files to BMP simultaneously
Best-possible quality during HEIC to BMP conversion
See file size estimates before downloading
All processing in your browser — complete privacy
Convert as many HEIC files to BMP as you need
Find answers to common questions
BMP is appropriate when you need uncompressed pixel data — for example, feeding images into scientific imaging software, machine vision systems, or legacy applications that only accept BMP. For general sharing or web use, JPEG is a much better choice.
Dramatically larger. A typical iPhone HEIC photo might be 3–5 MB. The same image as BMP will be 15–25 MB because BMP stores every pixel without compression. Ensure you have enough storage and that your target application can handle large BMP files.
32-bit BMP supports an alpha channel for transparency, but support varies by software. If you need reliable transparency, convert to PNG instead — it has universal transparency support and much smaller file sizes than BMP.
Yes. The still image component of a HEIC Live Photo is converted to BMP. The motion (video) component of Live Photos is separate and is not included in the HEIC file itself.
Yes. AppyGrid tools are free to use for personal and commercial purposes with no attribution requirement, no watermarks, and no file limits.
