Batch convert PNG to JPG, from chat
Ask ChatGPT or Claude to turn a folder of PNG screenshots and graphics on your Mac or Windows PC into smaller JPGs. One message, every file, no converter websites and no dragging files around.
Works in ChatGPT and Claude, on the web and on your phone. See how it works in ChatGPT or Claude.
PNG files are huge. Too huge.
Screenshots, graphics, and saved images come as PNGs, and they're massive. Your email bounces because attachments are too large. Your website loads slowly. Your storage fills up. You need JPGs, but converting them one at a time on a website wastes your time.
Describe what you want. It handles the rest.
No settings to configure. No software to learn. Just describe what you need in ChatGPT or Claude.
Converted 64 screenshots to JPG.
- •Found 64 PNG files on your Desktop.
- •Saved each one as a JPG at 90% quality.
- •Kept the originals. The JPGs are in Desktop/JPG and take 14 MB instead of 92 MB.
Batch convert in one message
Name a folder with hundreds of PNGs. Desktop Commander converts them all at once and tells you how much space you saved.
You say:
"Convert all PNG files in my Screenshots folder to JPG"
Result:
142 files converted, 1.2 GB of space saved
Organize while converting
Don't just convert. Move files to new folders, rename by date, or sort by size. One message handles the entire workflow.
You say:
"Convert these PNGs to JPG and organize by month"
Result:
Files sorted into Jan/, Feb/, Mar/ folders
Pick the quality you need
Need smaller files? Want maximum quality? Just say so. Desktop Commander sets the JPG quality to match.
You say:
"Convert to JPG at 85% quality for web use"
Result:
Saved at 85% quality, a good balance of size and detail for the web
