What's the difference between BMP and JPG?

BMP is a Windows-era uncompressed raster format. JPG (also written JPEG) is the workhorse lossy format for photographs.

What quality should I pick?

For JPG, quality 75-85 is the sweet spot — small files with no visible difference from the original. Lower than 60 starts to show artifacts. Higher than 90 mostly just makes the file bigger.

Why convert away from BMP?

BMP is a Windows-era uncompressed raster format. Where it falls down: anything where file size matters (which is almost everywhere); web display, email, archive — pick literally any other format. JPG addresses that for most workflows.

When is JPG the right format?

JPG is a good choice for: photographs, especially anything with smooth gradients (sky, skin, water); social media uploads where size matters more than perfect fidelity; email attachments and chat where compatibility is paramount. It is a poor choice when anything that needs transparency (use PNG or WebP).

Anything surprising about BMP or JPG?

BMP can technically carry a small palette and run-length compression, but in practice 99% of BMPs in the wild are uncompressed. And on the JPG side: JPG quality 80–85 is usually visually indistinguishable from the original. Don't ship q100.

Does this work on mobile?

Yes. The drop zone falls back to your phone's file picker, and conversions run on-device just like desktop. Large files may be slower on mobile due to CPU and memory constraints, but the workflow is identical.

What's the maximum file size?

No hard limit — the browser handles it. Files under 50MB convert in a few seconds. Larger files work but may take longer as the browser allocates memory. If you hit issues, batch in smaller groups.

Overview

Why convert BMP to JPG

JPG files are typically much smaller than BMP at equivalent quality — usually the main reason to make this conversion. Smaller files mean faster page loads, smaller email attachments, and less storage. BMP is uncompressed, so expect a dramatic size reduction.
