What is a PNG to JPG converter?

A PNG to JPG converter turns a lossless PNG file into a JPEG (JPG) image so you can shrink file size for the web, email, or photo uploads. People search for how to convert PNG to JPG, how to convert PNG to JPEG, change PNG to JPEG, or how to convert a photo to JPG when a site rejects PNG or when storage matters more than transparency. This tool flattens the image on a canvas, applies a quality setting, and downloads a JPG in the browser—no Adobe Express account and no upload to a remote converter. JPG does not keep alpha; keep PNG when you still need a transparent background.

How to convert PNG to JPG

Four steps to change a PNG image to JPEG.

  1. Upload your PNG

    Drop or choose a PNG file. Photos and graphics both work as long as the browser can decode them.

  2. Adjust JPEG quality

    Move the slider: higher keeps more detail; lower produces a smaller JPG for web or email.

  3. Preview the result

    Check edges and flat color areas for artifacts, especially below quality 70.

  4. Download the JPG

    Save the converted JPEG to your device. Use it for sites, attachments, or photo uploads that expect JPG.

Tips for converting PNG to JPEG

Get smaller files without surprising artifacts.
  • 01

    Use 80–92 for most web photos

    This range usually looks sharp while cutting a large PNG down to a practical JPG.

  • 02

    Go 95+ when detail matters

    Print layouts, hero images, and product zooms benefit from higher JPEG quality.

  • 03

    Avoid very low quality on text

    UI screenshots with small type show ringing and blockiness below ~60—raise quality or keep PNG.

  • 04

    Expect a white background

    If the PNG had transparency, preview the flattened JPG before you publish.

  • Ezgif.com
