JPG to PNG / PNG to JPG: Frequently Asked Questions
How do I convert a JPG to a PNG?
Simply drag and drop your JPG into the upload area above, select "Convert to PNG," and click Download. The conversion happens instantly in your browser.
Does converting JPG to PNG improve image quality?
No. Converting to PNG will not add missing details back into a compressed JPG. However, since PNG is a lossless format, saving as PNG prevents any further quality loss if you plan to edit the image repeatedly.
What is the difference between JPG and PNG?
JPG (or JPEG) is a lossy format ideal for photographs, offering small file sizes but no transparency. PNG is a lossless format that supports perfect transparency, making it ideal for logos, icons, and text-heavy graphics.
Why is my PNG file larger than my JPG?
Because PNG is a lossless format, it preserves pixel data exactly without heavy compression algorithms. This makes it structurally larger than a lossy JPG file.
