❓ FAQ
What is the difference between BMP and PNG?
BMP is an uncompressed format and produces very large files. PNG uses lossless compression to shrink file size significantly while preserving every pixel.
Is there any quality loss?
No. PNG is a lossless format, so no quality is lost during conversion.
Are my files uploaded to a server?
No. Everything is processed locally in your browser using the Canvas API.
Can I convert multiple files at once?
Yes. Batch conversion of up to about 100 files works reliably.
