BMP to JPG — Convert in Your Browser

Why convert BMP to JPG?

BMP stores raw pixels with no compression at all, so even a modest screenshot can run to tens of megabytes. JPG applies thirty years of image compression research and hands back a file small enough to actually send.

BMP stores raw, uncompressed pixels. It came from early Windows and still turns up in legacy tools, medical software and embedded systems — always at enormous file sizes.

When BMP → JPG is the right move

Clearing out legacy BMP exports from old Windows or medical software.
Emailing or uploading images that legacy tools saved uncompressed.
Reclaiming disk space in an old image archive.

Quality, size and what changes

Size reductions of 95% or more are normal, with no visible difference for photographic content. JPG has no transparency and is lossy, so keep BMP if the file feeds a system that specifically requires raw pixel data.

What you gain with JPG: Small photographic files that open literally everywhere, from a print shop kiosk to a decade-old phone.

How it works

Drop your BMP file above and Morphio decodes it locally, then re-encodes it as JPG using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.

BMP to JPG — frequently asked questions

How do I convert BMP to JPG without uploading the file?

Open the BMP to JPG page, drop your image on the drop zone and press convert. Morphio runs an in-browser image pipeline built on Canvas and WebAssembly codecs, so the BMP data never leaves your device and no server ever receives a copy.

Does converting BMP to JPG lose quality?

Colour profile and pixel dimensions are preserved; you choose the quality level before the file is written. Converting BMP to JPG only rewrites the container and encoding you asked for — the source file on your disk is never modified.

Is the BMP to JPG converter free, and how big can the file be?

Yes. The free plan covers 10 conversions a day with files up to 200 MB and adds no watermark or sign-up. Morphio Pro ($5/month, or $29 once for lifetime access) removes the daily cap and raises the per-file limit to 5 GB.

Why are BMP files so large?

BMP stores every pixel uncompressed — three bytes per pixel — so a 4000×3000 image is around 36 MB before it holds any detail at all.

Is JPG a safe replacement?

For viewing, sharing and archiving photos, yes. For pixel-exact technical imagery, convert to PNG instead.
