About this tool

BMP to JPG is the fastest way to shrink an uncompressed image - from scanners, older cameras or Windows software - into something you can email, upload or attach. JPG compression can cut file size by a very large factor for photographs, with little visible difference at a high quality setting. The JPG is far smaller. JPG is lossy, which is invisible on photographs but can soften fine text, so for scans of documents PNG is the better choice.

How to use this tool

  1. Add the BMP photosDrop in scanned photos or images from older cameras.
  2. Convert to JPGEach BMP is compressed to a JPG at a high quality setting.
  3. Send or uploadDownload the JPGs and attach them to an email or upload them anywhere.

Best for photos, not for text

JPG is designed for photographs. For scanned documents with sharp text, or screenshots, JPG can introduce smudges around edges; PNG keeps them crisp. If you are converting scanned photos or camera images, JPG at a high quality setting gives the best balance of size and appearance.

JPG for photos, PNG for screenshots

JPG is the right target when the BMP is a photograph - an old camera image or a scanned print - because its compression hides detail loss in natural texture. For screenshots, diagrams and scanned text, choose PNG instead: JPG blurs sharp edges and lettering slightly, which shows on those images.

If you are not sure, convert one file both ways and compare them at full size before converting a whole folder.

Frequently asked questions

Slightly - JPG is lossy, but at high quality the difference is hard to see in photos.

Often many times smaller for photographs.

Photos as JPG; text documents as PNG.

JPG is a lossy format, so a small amount of detail is discarded. At the quality this tool uses that is invisible on a photograph, but fine text and sharp edges - screenshots especially - can soften slightly.

Files usually come out noticeably smaller, because JPG compresses much harder than BMP.
