CR2 to BMP Converter

CR2 vs BMP — What You Gain and Lose Converting Canon RAW to Bitmap

CR2 is Canon's RAW format: it holds the unprocessed 14-bit sensor readout from an EOS DSLR, with white balance and exposure stored as adjustable metadata rather than baked into the pixels. BMP is Microsoft's Windows bitmap — finished, display-ready RGB pixels with no compression on top. Converting CR2 to BMP renders the RAW into a fixed, uncompressed image: you get a plain bitmap any Windows tool can read, but you trade away the editing latitude that made the RAW worth keeping. This page lays out that tradeoff, then converts the file.

Side-by-side Comparison

When to Keep CR2 (or Convert to Something Else)

• You still want to adjust white balance, exposure, or highlight/shadow recovery — those only stay editable in the RAW. Keep the CR2 as your master.
• You need a lossless but compressed copy to share or archive — CR2 to PNG gives the same pixel-exact render at a fraction of BMP's size, with real browser support.
• You need the smallest shareable photo — CR2 to JPG is far smaller and opens everywhere.
• You want to preserve higher-than-8-bit color in an editable file — CR2 to TIFF can carry 16-bit data that BMP output here does not.

When to Pick BMP

• A Windows application, legacy tool, or imaging pipeline specifically expects an uncompressed .bmp and won't accept PNG or JPG.
• You want pixels with zero post-render compression artifacts and don't care about file size — BMP stores exactly what the RAW rendered to.
• You're feeding the image into frame-by-frame analysis or scripting that reads raw bitmap rows directly.
• File size and web compatibility genuinely don't matter for the destination — otherwise PNG is the better lossless choice.

How to Convert CR2 to BMP

1. Upload Your CR2 File: Click "+ Add Files" to drag and drop your Canon CR2, or select it from your device. You can queue several RAW files to convert with the same settings.
2. Set the Quality Preset: Open Advanced Options and pick a Quality preset (it defaults to High). This governs how the RAW is rendered into the bitmap; High keeps the most detail from the demosaic.
3. Adjust Image Resolution (Optional): Use Image resolution to keep the original dimensions, scale by Resolution Percentage, choose a Preset Resolution, or set an exact Width × Height — handy for taming the large pixel count before it becomes an even larger BMP.
4. Convert and Download: Click "Convert" and download your BMP. No sign-up, no watermark.

Frequently Asked Questions

Will I lose editing flexibility converting CR2 to BMP?

Yes — that's the main thing to understand. The RAW stores unprocessed 14-bit sensor data with white balance and exposure as adjustable settings. Rendering to BMP bakes those decisions into fixed pixels, so you can no longer non-destructively recover blown highlights or re-do the white balance the way you could in the RAW. Keep the original CR2 as your master and treat the BMP as a finished export. If you want an editable high-bit file instead, CR2 to TIFF preserves more headroom.

Why is the BMP so much larger than the CR2 file?

Because BMP applies no compression to the rendered pixels. A 20-megapixel Canon RAW (around 5472 × 3648) becomes a 24-bit BMP of about 5472 × 3648 × 3 bytes ≈ 60 MB of raw pixel data — and that's deterministic math, not an estimate. The CR2 itself is smaller because it stores losslessly compressed sensor data. If that size is a problem, CR2 to PNG is lossless too but compressed, usually a fraction of the BMP.

Does converting to BMP add any quality loss?

No new compression loss after the render — BMP stores the rendered pixels exactly, with nothing thrown away on top. The loss that matters happens earlier, at the render step: the converter demosaics the RAW and bakes in white balance and exposure, which collapses the RAW's adjustable latitude into one fixed interpretation. The pixels you get are exact; what you lose is the ability to re-render them differently later.

What bit depth is the BMP output?

The output is a standard 24-bit true-color BMP — 8 bits each for red, green, and blue. The CR2 sensor captures up to 14 bits per channel, so the conversion maps that down to 8-bit per channel for the bitmap. If you specifically need to retain more than 8 bits of tonal data in an editable file, BMP isn't the right target; CR2 to TIFF can hold 16-bit data instead.

Should I convert my CR2 to BMP, PNG, or JPG?

For most people, PNG is the better choice: it's lossless like BMP but compressed, so you get the same pixel-exact render at a much smaller size and with native browser support. Pick JPG when you just need a small, shareable photo. Choose BMP specifically when a Windows tool or imaging pipeline requires a plain uncompressed bitmap and won't take anything else.

Will the BMP open on my phone or in a browser?

On the desktop, yes — BMP opens in Windows Photos, Paint, and essentially every image editor (Photoshop, GIMP, IrfanView). But most web browsers don't render BMP inside an <img> tag, and many phone galleries support it only partially. In our testing, a full-resolution 20 MP BMP also runs near 60 MB, which is awkward to send or post. If you plan to view it on mobile or share it online, PNG is the safer and far smaller format.

How are my files handled, and how long are they kept?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
