JPG and PNG are the two most common image formats, but choosing the wrong one can make your images blurry, oversized or missing their transparent background.
Here is a simple, practical comparison so you always pick the right format.

Quick answer
- Use JPG for photographs and images with many colours and gradients.
- Use PNG for logos, icons, screenshots, text-heavy graphics and anything that needs a transparent background.
- Use WebP on websites when you want the smallest file size.
Compression: lossy vs lossless
JPG uses lossy compression: it throws away detail the eye barely notices to make files much smaller. Each time you edit and re-save a JPG, a little more quality is lost.
PNG uses lossless compression: every pixel is kept exactly. That keeps text and sharp edges crisp, but photos saved as PNG can be 5–10 times larger.
Transparency
PNG supports full transparency, which is why logos placed on coloured backgrounds are usually PNGs. JPG has no transparency — transparent areas turn white or black.

Frequently asked questions
Is PNG higher quality than JPG?
PNG is lossless, so it keeps more detail, but for photos the visible difference is often small while the file is much bigger.
Which is better for Instagram or Facebook?
Upload high-quality JPGs; social networks recompress images anyway.
Which format is best for printing?
High-quality JPG or TIFF for photos, PNG or PDF for graphics with text.
