What does converting BMP to PNG mean?
BMP is an uncompressed raster format that stores every pixel with no compression at all, while PNG is a lossless raster format that preserves every pixel exactly, including transparency. Get a lossless, compressed version of your BMP — smaller file, same image quality.
BMP files are typically 10-20 times larger than an equivalent JPG or PNG because no compression algorithm is applied. It remains common in Windows-native applications and legacy software.
PNG uses lossless compression, so zero image data is discarded, which makes it the standard choice for logos, icons, screenshots, and graphics with sharp edges or transparency. The tradeoff is larger file sizes for photographic content compared to lossy formats.

When to convert BMP to PNG
Preparing BMP files for logos, icons, and graphics with transparency
Convert BMP images to PNG when your project specifically calls for logos, icons, and graphics with transparency.
Reducing file size
If PNG compresses better than BMP for your content, converting can significantly cut storage and bandwidth needs.
Improving compatibility
Some platforms and software only accept certain formats — converting to PNG ensures your BMP files open everywhere they need to.
Batch migrating a library
Convert a whole folder of BMP images to PNG at once instead of opening each file individually in an editor.

Frequently Asked Questions
Will converting BMP to PNG reduce image quality?
Since PNG is a lossless format, no additional quality is lost during this conversion. If your original BMP file was already compressed with quality loss, that original loss can't be recovered, but nothing further is discarded.
Does PNG support transparency?
Yes, PNG supports transparency, so any transparent areas in your BMP file are preserved in the converted image.
Is it safe to convert my images here?
Yes. All conversion happens locally in your browser using the Canvas API — your files are never uploaded to a server.
Can I convert multiple files at once?
Yes, drop several files at once and click Convert All — every file is processed and can be downloaded individually or as a ZIP.
Is there a file size limit?
There is no hard limit set by Pixvert, but very large files depend on your device's available memory to process smoothly.
Can I use the converted images commercially?
Yes, Pixvert only changes the file format — it does not alter your rights over the image or add any watermark.
