BMP to JPG/PNG Converter

Convert BMP images to JPG or PNG. BMP files are large and uncompressed — converting to JPG or PNG reduces file size by 90%+ with no visible quality loss for most images.

How to use BMP to JPG/PNG Converter

Image tools guide for bmp to jpg/png converter users.

BMP (Bitmap) is an uncompressed raster format used by Windows. A single BMP photo can be 5–20 MB because it stores every pixel with no compression. Converting to JPG reduces this to 200–500 KB for a photo; PNG reduces it to 1–3 MB while remaining lossless.

This tool runs in your browser using the Canvas API. No file is uploaded. Batch conversion lets you convert multiple BMPs at once.

What this tool does

Decodes BMP files and re-encodes them as JPG or PNG. JPG gives the smallest file size; PNG is lossless. Both are universally supported.

How to use it

Upload one or more BMP files. Choose JPG or PNG as the output format. Set quality (JPG only). Click Convert and download.

Best practices

Choose JPG for photos — the quality difference at 85–90 is invisible and the file is 10× smaller. Choose PNG for screenshots, diagrams, or images with text.

Quick checklist

Upload BMP files and choose JPG or PNG output.
For photos, JPG at quality 85 is optimal — half the size of PNG with no visible loss.
For screenshots with text or sharp edges, use PNG to avoid JPG artefacts.
BMP files don't support transparency — if you need transparency, use PNG output and note the background will be white.
