JPEG to JPG, in your browser
JPEG and JPG are the same format – the three-letter .jpg extension dates from old Windows systems that only allowed three characters. Some upload forms check the extension literally and reject “.jpeg” or “.JPEG”. This tool re-saves the image as a standard lowercase .jpg so the form accepts it. At 100 % quality the picture is unchanged.
How to convert JPEG to JPG
- Add the JPEG files. Click the sheet or drag them in. You can add other formats in the same batch.
- Check the quality. 92 % is visually identical; 100 % for no recompression at all.
- Convert and download. Each file becomes a .jpg with the same name. Several files arrive as a ZIP.

Frequently asked questions
Is JPEG the same as JPG?
Yes, identical format. Only the file name ending differs.
Can I just rename the file?
Yes, renaming .jpeg to .jpg works for one file on a computer. On a phone, or for many files, converting here is quicker. Set quality to 100 % to keep it unchanged.
Is the JPEG file uploaded?
No. The image is read and converted by your browser on your own device. Nothing is sent to a server, and nothing is stored.
Can I convert several JPEG files at once?
Yes. Add as many as you like; each becomes a JPG, and they download together as a ZIP.
Is there a size or daily limit?
No limits and no watermark. Very large images (over about 50 megapixels) may be slow on older phones because the work happens on your device.
