Free BMP to JPG Converter Online BMP in. JPG out. From Windows to the web.

Windows-era bitmaps weighing in at megabytes, re-issued as JPGs an order of magnitude smaller — without ever leaving your browser tab. Conversion runs instantly in your browser tab — no upload, no cloud, no per-seat ladder.

What it actually does

01
DECODE

Raw BMP bitmap data, parsed in the tab.

No server. The browser reads the BMP header, we read the pixel grid, then re-encode.

02
ENCODE

JPG comes out at modern compression ratios — typically 10–20× smaller than the source BMP.

Photographic quality preserved. Visual difference: imperceptible at normal viewing distances.

03
KEEP

BMP and JPG both stay on your machine.

Nothing ever uploads. The conversion is local-first by architecture.

04
BATCH

Convert a folder of BMPs in one drop.

Each file processes independently. No queue, no rate limit, no daily cap.

How it works

  1. Open morph.cool in any modern browser.
  2. Drop your .bmp file onto the drop zone, or click to browse.
  3. Pick JPG as the output format.
  4. Download your converted .jpg file. Done in seconds.

Why it lives in the tab

BMP is the format Windows built when storage was cheap and the internet was a dial tone. It stores every pixel raw, with no compression and no smarts. That's why a single screenshot can balloon to 30+ MB. Converting to JPG re-encodes the pixel grid through a modern lossy codec — the same one your phone camera uses — and produces a file an order of magnitude smaller without any visible loss. The conversion runs in your browser tab, so no BMP ever leaves your machine.

Frequently asked

Why are BMP files so large?

BMP stores every pixel uncompressed. A 4K bitmap is 33 MB before any image data. JPG's whole purpose is to compress that down to something the web can ship in milliseconds.

Will the conversion lose detail?

JPG uses lossy compression, but at default quality the loss is invisible to the human eye. For most BMPs — screenshots, photos, scans — you'll never see a difference.

What if I need lossless?

Pick PNG instead — also free, also local. BMP → PNG keeps every pixel exact and still ships ~2–4× smaller than the source.

Does this work for old Windows BMPs?

Yes — RGB, RGBA, indexed-color, and run-length encoded variants all parse correctly.

Is there a maximum BMP size?

Practical limit is your device's RAM. A 100MB BMP works fine on most modern hardware.
