Frequently Asked Questions
What should I know before converting BMP to PNG?
Compression depends on the actual pixels and dimensions. PNG often suits flat graphics, but conversion alone does not guarantee a smaller download.
Are my files uploaded?
Conversion reads the source and generates downloads on your device. Your file content is not sent to our server. Keep the tab open until processing and downloads finish.
What are the file and batch limits?
Each file is limited to 50 MB. Batch files are processed separately. Decoded images and document pages can use much more memory than the source file; try fewer or smaller files if processing fails.
