BMP to PNG: what changes?
The PNG result
PNG saves the decoded RGB and alpha values with lossless compression. It is useful for diagrams and screenshots where a JPEG save is undesirable.
Explore the PNG converterThe conversion preserves decoded image pixels, not every BMP header field, color profile or application-specific record.
A PRACTICAL GUIDE
BMP and PNG: choose the right result
A BMP file may not be accepted by the app or upload form you need. BMP to PNG creates a separate PNG copy while leaving your original file untouched.

Frequently asked questions
What does BMP to PNG preserve?
PNG saves the decoded RGB and alpha values with lossless compression. It is useful for diagrams and screenshots where a JPEG save is undesirable. The conversion preserves decoded image pixels, not every BMP header field, color profile or application-specific record.
What should I check before using BMP to PNG?
The BMP container may use palettes, direct RGB pixels, or other variants. Browser decoding determines whether a particular source can be read. Check the PNG result before replacing the source.
What is the BMP to PNG image limit?
Choose one BMP file up to 25 MB and 12 million pixels. The maximum side is 65,535 pixels. Resize larger sources first; this route does not silently reduce their dimensions.
Does BMP to PNG upload my file?
No. The BMP to PNG work runs in a local background worker. Needed converter files download on first use; your selected image is not sent to a conversion server. You can cancel processing.
