JPEG and JPG are the same format
JPEG is the name of the format. The extension is .jpg on files from older Windows versions, which allowed only three letters, and .jpeg on most others. They hold the same kind of image, and every program that opens one opens the other. This converter saves the file as .jpg. If a form asks for .jpeg, rename the file after downloading. Nothing else needs to change.
How to convert PNG to JPEG
- Drop the .png files on the box or choose them from your device.
- They are converted at full size as soon as they are added.
- Download each JPEG, or all of them in one ZIP. A file called logo.png becomes logo.jpg.
Quality settings in plain words
| Quality | Use it for | Size compared with quality 95 |
|---|---|---|
| 95 | Print and archives | Largest |
| 90 | General use, the default | About 70 to 80 percent |
| 85 | Websites and email | About 55 to 65 percent |
| 75 | Small uploads and previews | About 40 to 50 percent |
The exact savings depend on the picture. Photos shrink the most, flat graphics the least.
Why a form may say your file is the wrong type
Some portals check the file extension and reject .png even when they would accept the image. Converting to JPG solves it. If the form also has a size limit, use convert PNG to JPG and set a target size in KB.
