Screenshots: should you save PNG or JPG?
PNG keeps text and interface graphics perfectly sharp. JPG shrinks photos and busy screens quickly. Match the format to what the screenshot contains.
Why PNG suits most screenshots
Screenshots are full of text, buttons, and flat color — exactly the content JPG compression handles worst. PNG stores these areas losslessly, so text stays crisp and edges stay clean.
That is why PNG is the default choice for documentation, tutorials, and UI work.
When JPG is the better trade
A screenshot of a photograph, a video frame, or a busy gradient-heavy app compresses well as JPG. The smooth areas hide the artifacts, and the file shrinks considerably.
If a support form or email system limits attachment size, converting a large screenshot-heavy file to JPG can bring it under the limit.
A practical workflow
Save UI and text screenshots as PNG. If the file is still too large, resize it to the width it will actually be displayed at rather than compressing harder.
Convert photo-like screen captures to JPG when the source makes it worthwhile, and compare both outputs at 100 percent zoom before choosing.
