Convert PNG to JPG — free, without uploading your images

PNG files are huge, and plenty of forms won't take them. Converting to JPG fixes both — here's how to do it in seconds, free, right in your browser, with nothing uploaded.

Why convert PNG to JPG at all

How to convert here (free)

  1. Open the free image converter.
  2. Drop in your PNGs (any number up to the daily free allowance).
  3. Set output format to JPG, quality 90% for screenshots or 85% for photos. Leave dimensions unchanged if you only want a format change — set "prevent upscale" and a max size larger than your images.
  4. Download the JPGs.

The conversion runs inside the page — no upload, no account. It also works in reverse if you need it: set output to PNG to go JPG → PNG.

The transparency catch (and how it's handled)

JPG has no transparency layer. A PNG logo on a transparent background becomes either black or white behind the image, depending on the converter. For screenshots and photos this never matters — they have full backgrounds anyway. For logos and graphics, keep them as PNG: that's what PNG is for. This tool composites transparent areas onto white, so nothing turns black unexpectedly.

Questions people ask

Will the JPG lose quality?

JPG is lossy, but at quality 85–90% the difference is invisible in normal use — and the file is a fraction of the size. The quality slider puts you in control.

What happens to transparent areas?

They're composited onto white (JPG has no transparency). For logos that need transparency, keep them as PNG — this tool lets you choose the output format.

Does converting change the image dimensions?

Only if you want it to. Leave the size settings alone for a pure format change, or set a max dimension to resize at the same time.

Are my images uploaded anywhere?

No. The conversion runs entirely inside the page — no server, no account, no network calls. Wi-Fi off? Still works.
