Convert JPEG to JPG
Same format, shorter extension: get a .jpg copy of any .jpeg file on your own device.
- Nothing is uploaded
- Works offline after first visit
- Open source
- No watermark · limit is your device’s memory; phones hold less
JPEG and JPG are the same format; only the extension differs. It is free, needs no account and adds no watermark, and your files are not uploaded: everything runs in your browser on your device. The size limit is your device’s memory, and phones hold less; give the page a short while after one visit to save itself for offline use, and then it works offline.

A .jpeg file and a .jpg file are the same kind of picture. Drop .jpeg files here and you get a .jpg copy of each one, and the same works the other way if you have a .jpg and want a name that ends in .jpeg.
Is JPEG the same as JPG?
Yes. Both names stand for the Joint Photographic Experts Group format, and a file ending in either one opens in the same programs with the same quality. The three-letter .jpg exists because early versions of Windows only allowed three-letter extensions; Macs and Linux kept .jpeg. Some upload forms accept only one spelling, which is the usual reason to change it.
How to change JPEG to JPG
There are two ways, and the first is the lossless one. Rename the extension: change .jpeg to .jpg in the file name. Nothing inside the file changes, so there is no quality loss at all.
Use this page: it decodes the picture and encodes it again as a JPG at the quality you set (90 to begin with), and saves that as a new .jpg file. Because the picture is compressed a second time, a little quality is lost, and the file size can change. Use it when you have many files, or cannot rename them, but rename when you only need the extension changed.
JPG to JPEG
This page covers the other direction too. To get .jpeg from a .jpg, rename the file; the contents are already a JPEG. Tools that insist on a .jpeg extension read it exactly the same.
Not sure which format you have? Convert any image to JPG accepts PNG, WebP, HEIC and more as well.
How it works
- Drop your JPEG files onto the page, or tap to pick them. Batches are fine.
- Adjust the quality slider if you want a smaller file, or leave it at 90.
- Download each JPG, or all of them as one zip.
In your browser, not on a server
Stayput first reads the opening bytes of each file, where every image format writes its signature, so it knows what the file really is whatever it is called. Your browser decodes JPG, PNG, WebP, GIF, BMP, AVIF and SVG itself; TIFF goes through UTIF.js, HEIC through the libheif WebAssembly decoder, and JPEG XL (or AVIF, in a browser without native support) through the Squoosh decoders, all served from this site and cached. The browser re-encodes JPG, PNG and WebP; PDF, ICO, GIF, BMP and TIFF files are written by small encoders in the page. Nothing here needs a server.
Compared with upload-based tools: Online converters upload your image, convert it on their machine, keep it for hours and cap you at a few files a day. This does the same conversion on your device, for as many files as your device’s memory can hold, with no upload to wait for.
Verify it yourself. Give the page a short while after one visit to save itself for offline use, then turn off Wi-Fi or switch to airplane mode and run the tool again. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.
Questions
Is JPEG the same as JPG?
Yes. They are one format with two spellings of its name. The file contents are identical whichever extension is used.
Will the quality change?
Renaming the file changes nothing. Using the converter on this page decodes and encodes the picture again, which loses a small amount of quality, so rename if you only need the extension changed.
Are my files uploaded?
No. Each picture is decoded and written as a JPG by code running in this browser tab, and nothing leaves your device.
Can I convert many files at once?
Yes. Drop a whole folder of .jpeg files, and download the JPGs one by one or as one zip. A very large batch is limited by your device’s memory.
