How to Convert PNG to JPG on Windows

Step-by-step instructions

1. 1

   Convert using Microsoft Paint

   Right-click the PNG file → Open With → Paint. In Paint, go to File → Save As → JPEG picture. Choose a save location and filename. Click Save. Paint saves at its own quality setting around 85%. For more quality control, use the Photos app or command-line tools.

   Convert using Photos app

   Open the PNG in the Photos app (double-click opens it by default on Windows 11). Click the three-dot menu at the top right → Save as. In the Save dialog, change Save as type to JPEG. Click Save. The Photos app gives you a clean JPG without compression artifacts at the default quality.

3. 3

   Batch convert with PowerShell

   Open PowerShell. Run: `Get-ChildItem -Filter *.png | ForEach-Object { $out = $_.FullName -replace '\.png$', '.jpg'; [System.Drawing.Image]::FromFile($_.FullName).Save($out, [System.Drawing.Imaging.ImageFormat]::Jpeg) }`. This converts all PNGs in the current folder. Requires .NET which is built into Windows 10/11.

   Verify and clean up

   Open the JPG files to confirm they look correct. PNG transparency appears as white in the JPG. Compare file sizes — for photo-type images, JPG should be 50–80% smaller. If the quality looks too low, try FFmpeg for quality control: `ffmpeg -i input.png -q:v 2 output.jpg` (q:v 2–5 is high quality).
