BMP to PNG Converter — Free, No Upload | Input and conversion guide
Turns a BMP bitmap into a PNG file that is easier to use in common web and document workflows.
- Runs in your browser
- Nothing is uploaded
- No signup; device limits apply
How to use this tool
Select the BMP and check whether the workflow requires the original pixel dimensions to be retained.
Results and examples
Open the PNG to inspect colors, edges, and file size before replacing the BMP.
Worked example
Export an old BMP screenshot as PNG, then compare its original pixel dimensions and small text at the same zoom level.
Limitations
- The conversion writes raster pixels to PNG; it does not create vector shapes or editable layers.
- Unsupported BMP variants or damaged headers may fail during decoding.
Data handling
Processing stays in the current browser tab; the site does not upload tool input for the calculation itself.

Frequently asked questions
Is the resolution increased?
There is no resizing option; the decoded dimensions are used for PNG output.
Does a smaller PNG mean missing content?
The formats encode pixels differently, so byte count alone does not establish visual loss.
