Choose by use

Photos and documentsChoose JPG when you do not need transparency.
Logos, icons, and UIChoose PNG for transparent backgrounds and crisp edges.
Images used on websitesTry WebP when you want a smaller web image.

Image formats are different ways to save a file, not a simple quality ranking. The best choice depends on the image, the file size you need, and the app where you will use it.

Why JPG and WebP work well for photos

Photos contain many colors and subtle changes. JPG and WebP can reduce that data to make a smaller file, while PNG often stays much larger.

For small text, faces, hair, and product edges, open the result at the size it will actually be used.

Why PNG works well for logos and screenshots

PNG keeps transparent backgrounds and crisp graphic edges. It is a good fit for logos, icons, UI, and screenshots with text.

What changes during conversion

Conversion saves the current pixels in a new format. Transparent areas become white in JPG, and an animated WebP becomes one still image. Keep the original when you need its camera information.

Choose a format in three steps

  1. Check which formats the destination accepts.
  2. Decide whether you need a transparent background.
  3. Compare the file size and percentage change after conversion.
