FAQ

Are JPEG and JPG different formats?

No, they are exactly the same format. "JPEG" is simply the full acronym (Joint Photographic Experts Group). You can safely convert both .jpeg and .jpg files interchangeably using this tool.

Will converting a JPEG to PNG make the background transparent?

Converting the file format alone won't magically remove the background or create a cutout. However, changing it to a PNG is the necessary first step, as JPEGs natively cannot support transparent backgrounds (Alpha channels). Once it is a PNG, you can use other image editing tools to erase the background.

Is there a file size limit for my JPEGs?

No! Because the conversion happens entirely locally on your own computer or device, there are no artificial file size limits, hidden quotas, or paywalls. You are only limited by your device's available memory.
