Frequently Asked Questions

Why should I convert BMP to PNG?
PNG offers identical lossless quality but with smart compression, reducing file sizes by 60-80%. Unlike BMP, PNG supports transparency and metadata, making it the standard for web use and design studios across Canada.
How much size reduction can I expect?
You can typically expect a 60-80% reduction. For instance, a massive 25MB BMP screenshot from a desktop in Montreal can be compressed to a 5-10MB PNG with zero visual difference.
Will I lose quality converting BMP to PNG?
No, not at all. Both formats are lossless. Every single pixel is preserved perfectly; PNG simply stores the data more efficiently to save storage space.
Is PNG always better than BMP?
For nearly every purpose, yes. PNG offers transparency, web compatibility, and massive space savings. BMP is only necessary if you are using specific legacy software or older Windows systems.
Are my images safe and private?
Definitely! The conversion runs entirely in your web browser. Your photos are never uploaded to a server, ensuring privacy whether you are in Ottawa, Calgary, or anywhere else.
