How to convert JPG to PNG on Mac
Right-click the JPG in Finder and choose FileMate › Convert Image › PNG. The PNG is saved next to the original. Preview (File › Export › PNG) and Finder’s Quick Actions › Convert Image do the same. Converting doesn’t improve quality or add transparency: the PNG keeps the JPG’s pixels exactly, including its white background, and the file is usually larger.
FileMate converts the image on your Mac, without uploading it.
Convert JPG to PNG with FileMate
- Select the JPG images in Finder.
- Right-click and choose FileMate › Convert Image › PNG.
- The PNG is saved next to the JPG, with the same name.
Why convert a JPG to PNG?
- Something requires PNG. Some app stores, design tools, print services and upload forms accept only PNG.
- You’ll edit it repeatedly. PNG is lossless, so saving it again and again doesn’t add JPEG artefacts on top of each other.
- It’s a graphic that was saved as JPG by mistake, and you want further edits to stay crisp.
What converting won’t do
- Restore quality. Detail the JPG compression removed is gone. The PNG preserves the JPG exactly as it is, artefacts included.
- Make the background transparent. A JPG has no transparency. The white or coloured background stays in the PNG. Removing it is an editing job, for example with the Instant Alpha tool in Preview’s markup toolbar.
- Make the file smaller. A photo as PNG is typically several times the size of the JPG.
With Preview
Open the JPG, choose File › Export, choose PNG, and save. For a single image, that’s quick. For a folder of them, select them all in Finder and use FileMate’s Convert Images › PNG.
Get FileMate
When a site, a tool or a print shop asks for PNG, FileMate makes one from Finder, on your Mac, next to the original.
