PNG to JPG Converter — Free Online

PNG screenshots and exports are often needlessly large for sharing by email or uploading to a form. Converting to JPG typically cuts the size by 70% or more with no visible difference. Transparent areas are filled with white, since JPG has no transparency.

How to use the png to jpg converter

  1. Drop your PNG files into the box above.
  2. Choose a quality level — 90% keeps screenshots crisp.
  3. Compare the before and after sizes, then download.

Transparency becomes white

This is the one thing to know before converting. JPG has no alpha channel, so any transparent pixel has to be given a colour, and that colour is white. A logo saved as a PNG with a see-through background will come out as a logo on a white rectangle — perfect for a Word document or a printed page, wrong for placing over a coloured website header or another image.

The failure is easy to miss because transparency often looks white on screen already. If the image is a logo, an icon, a signature or a cut-out product shot that needs to sit on top of something else, keep it as PNG or convert it to WebP, which keeps the alpha channel and is still far smaller than PNG.

Screenshots versus photographs

PNG to JPG pays off enormously on photographs — a phone photo mistakenly saved as PNG can drop by 90% with no visible change, because JPG was designed for exactly that content. Screenshots are the opposite case. They are full of sharp text, thin lines and flat blocks of colour, and JPG's compression produces faint halos and coloured fringing around every letter that is very noticeable at 100% zoom.

If you are converting screenshots anyway — because a form demands JPG, or because the file is too large to attach — stay at 90% or above and check the smallest text before you send it. For anything where the text has to be crisp and the size is not critical, PNG is still the right format, and cropping to the region that matters usually saves more than any conversion would.

How much smaller is PNG to JPEG?
Photos and soft screenshots often shrink 70–90%. Flat logos may look worse as JPG and should stay PNG or become WebP with transparency.

No. JPG discards data permanently. Converting back to PNG restores the format, not the lost detail — keep the original PNG.
