How do I convert JPEG to JPG?+
Drop your .jpeg files on the box at the top of this page, or click it to choose them. Each picture opens in the Compix editor as a page of its own, with the Download menu already on JPG. Press Download: one picture comes back as a .jpg, several come back in one zip of .jpg files, each named after its file.
Is JPEG the same as JPG?+
Yes. JPEG and JPG are two endings for one picture format, made by the Joint Photographic Experts Group. A file is not better or worse for ending in either. Most apps open both; a few forms and older programs check the ending and take only .jpg.
Why do some pictures end in .jpeg and others in .jpg?+
Early versions of Windows allowed only three letters after the dot, so .jpeg was cut down to .jpg there. Other systems kept the full .jpeg, and both endings are still in use today.
Can I just rename .jpeg to .jpg?+
Yes, and renaming keeps the file exactly as it was. On Windows, turn on File name extensions in File Explorer's View menu (under Show on Windows 11) and change the ending; on a Mac, click the name, change the ending and choose Use .jpg. This page helps when there are many files, when you are on a phone, or when you want what saving again does.
What does converting do that renaming does not?+
It saves each picture again as a new file. A phone photo that was stored on its side is saved the right way up, and the place it was taken and the camera it came from are left out of the new file.
Will the quality drop?+
Not so you could see it. Saving a JPEG again changes it very slightly, and Compix saves at high quality, so the new file looks the same as the old one. If every byte must stay as it was, rename the file instead.
Will the new file be bigger?+
For a photo it stays close to the size it was, often a little bigger. A simple picture of flat colours can come out smaller.
Is there a size limit?+
On a computer each picture keeps its full size up to 64 megapixels or 16,384 pixels on its long side. On an iPhone or iPad, a picture larger than about 16 megapixels is brought in at about 16, the most the browser there can draw: a 24 megapixel photo comes back with about two thirds of its pixels.
Can I convert many JPEG files at once?+
Yes. Drop them all together. Each becomes a page, the Download menu is set to all pages, and one zip comes back, named after the first file, with a .jpg for each picture in the order you dropped them. When two files share a name, the second one ends in -2.
What about .jfif files and capital letters?+
A .jfif file is a JPEG too; some Windows computers save pictures from the web that way. Drop it here and it comes back as a .jpg. A file ending in .JPEG in capitals comes back as .jpg as well.
Why does my photo show up sideways?+
Phones often store a photo on its side with a note saying which way to turn it, and some sites and apps ignore that note. The .jpg from here is stored the right way up, so it shows upright even where the note is not read.
Is the location of my photo kept?+
No. The new .jpg holds the picture only: the place a phone photo was taken and the camera it was taken with are not in it.
Are my files uploaded?+
No. The pictures are opened and saved again as .jpg right here in your browser, on your own computer or phone; nothing is sent to a server for that. If you sign in to keep a design, it is saved online with its pictures, so it opens on any device.
Can I convert JPEG to JPG on my phone?+
Yes. Tap the box at the top of this page and choose your pictures; on a phone the editor shows one at a time. Tap Share, then Download the work: one picture saves as a .jpg, several save as one zip.
Is it free?+
Yes. There is no account to make and no watermark on the pictures.
