Convert PNG to JPG, free
PNG to JPG format: three free ways, and a whole folder at once
To convert PNG to JPG for free, open the image and save it in the new format. On a Mac, open it in Preview and choose File, Export, Format: JPEG. On Windows, open it in Paint and choose File, Save as, JPEG picture. On Linux, use GIMP 3 and File, Export As. JPG has no transparency, so transparent areas become a solid colour. For a whole folder, Convert Images in AwaCut converts every file at once and lets you pick that colour.
2 computers per licence. Full refund within 14 days, no reason needed.

Mistakes when converting PNG to JPG
Converting a cutout or a logo
A PNG with a transparent background loses it as JPG. Keep cutouts and logos as PNG, or pick the background colour on purpose.
Converting a screenshot with small text
JPG blurs sharp edges and text a little. Screenshots and diagrams stay sharper and often smaller as PNG.
Converting the same JPG back and forth
Every JPG save loses a little. Convert from the PNG original each time.
Why convert PNG to JPG
PNG keeps every pixel, which is right for graphics and wrong for photos: a photo saved as PNG is often several times larger than the same photo as JPG. Shops, forms and email limits want smaller files, and many upload forms accept JPG only. Converting photos to JPG fixes both.
Try it on your own photos: the first 10 are free, no account.

Frequently asked questions
How do I convert PNG to JPG on Windows?
Open the file in Paint, choose File, Save as, JPEG picture. For a whole folder, drop it on Convert Images in AwaCut.
What happens to the transparent background?
JPG cannot store transparency, so every converter fills it with a colour. Some give white, some black. AwaCut lets you choose white or any colour before converting.
Does PNG to JPG lose quality?
A little. At a high quality setting a photo looks the same; text and sharp lines show the loss first.
Can I convert many PNG files to JPG at once?
Yes. Convert Images in AwaCut converts a whole folder in one run on Mac, Windows and Linux. With ImageMagick: for f in *.png; do magick "$f" "${f%.png}.jpg"; done.
