About this tool

BMP files store pixels with little to no compression, which is why a modest image can weigh tens of megabytes. When the content is photographic and precision-per-pixel isn't required, JPG shrinks the file dramatically at a quality most viewers can't distinguish. This converter reads a BMP in the browser and encodes it as JPG, keeping the whole operation local. Typical BMP files have no alpha channel, and JPG cannot store one either, so the visible result matches the source. The tool handles one file at a time, up to about 25MB.

FAQ

More about this tool

How it works

  1. Load a BMP file from your device.
  2. The browser decodes the bitmap and encodes it as JPG.
  3. Download the compact JPG once encoding finishes.

Features

  • Big size drop — Photographic BMPs often shrink by an order of magnitude when saved as JPG.
  • No transparency involved — Standard BMPs have no alpha, so nothing is lost on that front.
  • Lossy encoding — JPG applies visible-quality compression; expect minor differences on flat regions.
  • Runs on your device — The BMP is decoded and re-encoded locally in the browser.
  • 25MB per file — Very large scans may need trimming before they can be processed.

Supported formats

Input: BMP. Output: JPG.

Common uses

  • Modernising legacy scans — Convert old BMP scans into JPGs that fit into today's storage and sharing tools.
  • Cutting archive size — Reclaim disk space by moving photographic BMPs to JPG.
  • Emailing images — Send photos that were originally saved as BMP without hitting mail attachment limits.

Limitations

  • JPG encoding is lossy; the pixels are not identical to the BMP.
  • Not ideal for BMPs made up of solid colors or line art.
  • Files must fit under roughly 25MB to be handled reliably.
  • One file per conversion.
