How to convert BMP to PNG
Converting BMP to PNG takes three quick steps:
- Add one or more BMP files — drag and drop them or click to browse.
- Click Convert to PNG and let the conversion run in your browser.
- Download your new PNG files individually or as a batch.
What is BMP?
BMP is an uncompressed bitmap format from Windows that stores raw pixel data. Files are very large because no compression is applied, but the format is simple and lossless, so it is sometimes used for intermediate editing or legacy software.
What is PNG?
PNG is a lossless image format that preserves every pixel exactly and supports a full alpha-transparency channel. It is the standard choice for logos, icons, screenshots and any graphic with sharp edges, flat colour or transparent areas.

Why convert BMP to PNG?
Converting BMP to PNG gives you a file that is better suited to logos and icons and screenshots, and that opens it up to far more apps, devices and websites.
What PNG gives you: lossless — no quality loss, full transparency support and crisp edges and text.
Where BMP falls short: huge file sizes, no transparency in common variants and poor support on the web. Converting keeps your content while moving to a format that matches where the file is going.
Tips for the best results
- PNG is lossless, so your converted files keep every detail of the original BMP.
- You can convert several files in one go — add as many BMP files as you like and download them together.
- Everything runs locally in your browser, so even large files convert quickly and nothing is uploaded.
