FAQ

Does this tool upload my images to a server?

Absolutely not. This JPG to PNG converter runs entirely in your browser using HTML5 Canvas technology. Your images are never uploaded to any server — all processing is done locally.

Will image quality improve when converting to PNG?

PNG is lossless, so there's no additional quality loss. However, compression artifacts from the original JPG cannot be fixed — PNG simply preserves all current pixel data without further degradation.

Why is the PNG file larger than the original JPG?

This is normal. JPG uses lossy compression to achieve small file sizes by sacrificing some data, while PNG uses lossless compression retaining all image data. PNG files are typically 3-5x larger but have no quality loss.

Can I batch convert multiple JPG files?

Yes. Select multiple JPG/JPEG files or drag and drop them. The tool will batch convert all files to PNG, and you can download each individually or all at once.

When should I use PNG format?

PNG is ideal for screenshots, charts, text screenshots, logos, icons, and images needing transparent backgrounds. For photographs, JPG is more space-efficient. For graphics requiring precise pixel-level detail, PNG is the better choice.
