Frequently Asked Questions

Convert BMP to JPG when you have photographic images and need maximum file size reduction. JPG's lossy compression can reduce files 10-20x smaller than BMP, perfect for sharing photos. Use PNG for graphics or when you need lossless quality.

Dramatically smaller—typically 90-95% reduction. A 10MB BMP might become 500KB-1MB as JPG. This makes photos practical for web sharing, email, and storage. Adjust quality settings to balance size vs. visual quality.

Yes, some quality loss occurs because JPG uses lossy compression. However, at high quality settings (85-95%), the loss is minimal and barely noticeable for photos. The trade-off is worthwhile for the massive file size reduction.

For photos: 85-90% provides excellent quality with great compression. For web sharing: 70-80% balances quality and size. For archival: 90-95% keeps near-perfect quality. Avoid below 60% unless file size is critical.

Use PNG for screenshots, graphics with text, logos, diagrams, or images with sharp edges. These types suffer visible artifacts with JPG compression. JPG is best for photographs and images with natural gradients.

You can convert back, but you won't recover the original quality—JPG compression is permanent. The quality loss from the BMP-to-JPG conversion is permanent. Always keep original BMPs if you might need lossless quality later.
