Convert BMP to JPG

BMP is an old Windows bitmap format that stores images with little or no compression, which makes the files huge and awkward to share. Converting to JPG shrinks them dramatically into a format every app and website accepts. PNGful does it in your browser.

How it works

  1. 1

    Add BMP files

    Drop, pick or paste — batch conversion is supported.

  2. 2

    Convert the files

    Each file is decoded and re-encoded as JPG in your browser.

  3. 3

    Adjust if needed

    Use the quality slider to trade size against detail.

  4. 4

    Download

    Single files or everything as a ZIP.

Why convert BMP to JPG?

  • JPG files are a small fraction of a BMP's size, which makes them easy to email, upload, and store.
  • Every device and website accepts JPG, whereas BMP support is increasingly patchy outside Windows.
  • For photographs saved as BMP, JPEG compression is a huge and near-invisible size win.
  • Free, watermark-free, and no account required.

Good to know

  • BMP is lossless; JPEG is lossy, so conversion discards a little detail in exchange for a much smaller file. A high quality setting keeps that loss unnoticeable for photos.
  • JPEG has no transparency, though most BMP files are opaque, so there's usually nothing to flatten.
  • For flat graphics and screenshots with hard edges, PNG avoids the faint artifacts JPEG can introduce.
  • The size reduction is often enormous because BMP stores raw pixels with essentially no compression.

Frequently asked questions

Why is my BMP file so large?

BMP stores each pixel with little or no compression, so even a modest image can run to many megabytes. Converting to JPG applies efficient compression and typically shrinks the file by 90% or more.

Will I lose quality converting BMP to JPG?

A small, usually invisible amount for photographs, since JPEG is lossy while BMP is lossless. Use a high quality setting to keep the result crisp, and keep the BMP if you need a lossless master.

Should I convert BMP to JPG or PNG?

Choose JPG for photos and when small size is the priority. Choose PNG for screenshots, logos, and flat graphics with sharp edges, where lossless quality matters more than file size.

Is the conversion free?

Yes. There's no account, no watermark, and no paid tier. The image is converted in your browser.
