How to convert JPG to JPEG
- Click Choose files or drop your .jpg files into the box above — up to 10 at a time on the free plan.
- That is all: each file is saved as .jpeg with its image data untouched. Files in other formats (PNG, HEIC, WebP…) are converted to JPEG at high quality.
- Download each file, or click Download all to get them as one ZIP.
JPG, JPEG, JFIF and JPE: one format, four extensions
| Extension | Inside the file | Where it usually comes from |
|---|---|---|
| .jpg | JPEG image | Phones, cameras and Windows — the most common spelling |
| .jpeg | JPEG image | Macs, some cameras, websites and image editors |
| .jfif | JPEG image | Pictures saved from Chrome or Edge on some Windows PCs |
| .jpe | JPEG image | Older Windows and Unix software |
The extension is only a label. The three-letter .jpg dates from early Windows versions that allowed only three characters, and .jfif shows up when a Windows setting registers it as the extension for JPEG images. Because the picture inside is identical, this tool copies it unchanged and only gives the file the extension you need. More in JPG vs JPEG: what is the difference?
Why GlideConvert?
- Private by design. Your files are converted on your own device by your browser — they are never uploaded to a server. That keeps them private, avoids upload waits and means there is no queue.
- Fast. Images convert in a fraction of a second; video uses your device’s hardware encoder.
- Free. No sign-up, no watermark. 10 images, 5 audio files or one video at a time — Pro lifts the limits and removes ads.
Frequently asked questions
Are JPG and JPEG the same?
Yes. They are two extensions for one format: the image data, quality and compatibility are identical. .jpg is more common only because early Windows versions limited extensions to three letters.
Why would I need .jpeg instead of .jpg?
Usually because a form, an online service or a program lists .jpeg as the accepted type and checks the extension literally. Some people also prefer one consistent naming style for a photo library. Either way, the picture itself does not need to change.
Does converting JPG to JPEG reduce quality?
No. With Keep the original JPEG data switched on (the default), the image is copied byte for byte — only the extension changes and, unless you choose otherwise, the GPS location is removed. Switch it off if you also want to resize or re-compress the photo.
Can I just rename the file instead?
Yes — the format is the same, so renaming photo.jpg to photo.jpeg works too. On Windows, turn on View → Show → File name extensions in File Explorer first. This tool renames a whole batch at once, works on phones, where renaming is awkward, and can remove the GPS location at the same time.
Can I convert several JPG images at once?
Yes. The free plan handles 10 images at a time, and you can download everything as a single ZIP. Pro removes the batch limit, converts files in parallel and supports files up to 4 GB.
Are my files uploaded to a server?
No. GlideConvert runs entirely in your browser: images are processed with the browser’s built-in codecs and WebAssembly, video and audio with hardware-accelerated WebCodecs (or a WebAssembly build of FFmpeg for older formats). Nothing is sent anywhere — you can even disconnect from the internet once the page has loaded.
Does it work on iPhone, Android, Mac and Windows?
Yes. It works in any up-to-date browser — Chrome, Edge, Safari, Firefox or Samsung Internet — on phones, tablets and computers, with nothing to install. On phones, extremely large images may be scaled down to fit within the browser’s memory limit; you will see a note if that happens.
