Why Compression Is Needed
Avoiding Bloated File Sizes
Saving a 4K camera photograph as a PNG can result in a 25MB file. Saving that exact same photo as a high-quality JPG might only take 2MB.
Preserving Text Clarity
If you save a graph or a text-heavy screenshot as a JPG, the compression algorithm will add ugly "mosquito noise" around the letters. PNG keeps sharp lines sharp.
Transparency Needs
JPG literally cannot support transparency. If you need a cut-out logo to float over a colored background, you must use PNG (or WebP/SVG).

Step-by-Step Guide
Analyze the Content
Look at the image. Does it have smooth gradients and millions of colors (Photo)? Or does it have flat areas of solid color and sharp text (Graphic)?
Check for Transparency
If there is a checkerboard background meaning it has an "Alpha Channel" (transparency), you must export as PNG.
Consider the Destination
If you are uploading to a strict government portal, they often demand JPG. If you are handing a logo to a designer, they demand PNG.
Use Converters When Boxed In
If a website demands a JPG but you only have a PNG logo, use our "PNG to JPG Converter." Note that transparent areas will be filled with solid white.

Frequently Asked Questions
Q. Can I convert a JPG to a transparent PNG?
Simply changing the format won't "create" transparency. You must use a Background Remover tool first, which will output the clean file as a PNG.
Q. Which is better for printing?
For professional printing, neither are ideal (TIFF or PDF is better). But between the two, a maximum-quality JPG or PNG are practically identical on paper.
