Convert JPG to PNG on Windows: 3 Methods

Your editor asks for PNG. The client sent JPEG exports. You need a lossless container for masking or a tool that rejects JPEG. Converting copies the same pixels into PNG. It does not remove compression artifacts from a weak source. Ask for a better master when quality matters; convert anyway when the pipeline requires PNG entry.

Method 1: GetCompress

Best for: One file or client folders that need JPG to PNG with an optional max width.

1. Open GetCompress and drop JPEG files or a folder into the queue.
2. Set output to PNG and optional max width (for example 2048 px for web proofs, higher for retouch).
3. Export copies to a dedicated folder so client originals stay untouched.

Save presets for retouch versus web proof. Processing stays on your PC.

Method 2: Paint

Best for: One file on any Windows PC.

1. Open the JPEG in Paint.
2. File → Save as → PNG picture.

Write outputs to png-out\ so originals stay untouched.

Limitation: Slow for fifty product shots from a client zip.

Method 3: FFmpeg in PowerShell

Best for: Scripted batches when you already use winget.

winget install --id Gyan.FFmpeg -e
mkdir png-out
Get-ChildItem *.jpg, *.jpeg | ForEach-Object {
 ffmpeg -i $_.Name "png-out\$($_.BaseName).png"
}

Optional resize for web (not print):

ffmpeg -i photo.jpg -vf scale=2048:-2 photo-2048.png

PNG from a 24 MP phone JPEG can exceed 25 MB. Resize in the same pass when the next hop is email.

Limitation: No visual preview before a large batch. Spot-check skin tones on a few SKUs if color management matters.

Which method should you use

If you need smaller uploads instead of PNG, stay on JPEG: compress images on Windows . To deliver JPEG again after editing, see PNG to JPG on Windows .

What this conversion does

Print vendors sometimes accept PNG but reject huge dimensions. Ask for max width before you convert two hundred catalog JPEGs. Cap width at the channel spec when the listing displays at 1200 px anyway.

When JPEG is the better stay

Stay on JPEG for email, CMS uploads, and client proofs when the workflow does not require PNG.

GetCompress fits when retouch handoffs need a lossless batch every week and you want consistent width without repeating Save as dialogs. Sort JPEGs into one folder, convert to PNG, then open only the PNG batch in your editor so accidental Save does not overwrite supplier originals. It does not restore detail that was never in the JPEG.
