# JPEG to JPG Converter > JPEG and JPG are the same format, so to convert JPEG to JPG you can simply rename the file from .jpeg to .jpg: nothing in the image changes and no quality is lost. If you can't rename it, or the file is a PNG or WebP, open it in Kenerate's Edit Studio (/app/edit) and pick Download → JPG, which saves a .jpg at full resolution for no credits. It needs a free account, takes one image at a time and handles up to 50 MB.

Your system may ask you to confirm the change, and it's safe to say yes. - Windows: in File Explorer open View → Show and turn on File name extensions, then select the file, press F2 and change the ending to .jpg. - Mac: select the file, press Return, change the ending to .jpg and choose Use .jpg when asked. - A whole folder on Windows: open Command Prompt in that folder and run ren *.jpeg *.jpg - A whole folder on Mac: select the files in Finder, right-click, choose Rename, then replace .jpeg with .jpg. ### Rename, JPG download or Convert: which one? All three end with a .jpg, but they do different things to the file: - Rename: no re-encoding, keeps metadata, works only if the file is already a JPEG. - Download → JPG in Edit Studio: no credits, works on PNG and WebP too, encodes the image again and drops metadata. - Convert in Edit Studio: 0.3 credits, runs on our servers and also exports PNG, WebP, AVIF, BMP, TIFF and GIF. ### When a site says your JPEG is the wrong format Some upload forms check the extension instead of the file itself, so a form that lists only .jpg can reject a good .jpeg. Renaming fixes that. If the form still refuses a file ending in .jpg, the real format may not be JPEG at all. Images saved from websites are sometimes WebP or AVIF with the wrong ending. Re-saving through Edit Studio writes a real JPEG.

Both are the same image format, and both use the media type image/jpeg. The only difference is the spelling of the file extension, so a .jpg and a .jpeg holding the same data are the same picture. Q: How do I convert JPEG to JPG? A: Rename the file and change the ending from .jpeg to .jpg. If you can't rename it, open it in Kenerate's Edit Studio at /app/edit and pick Download → JPG, which saves a .jpg at full resolution. Q: Does renaming .jpeg to .jpg lose quality? A: No. Renaming changes the file's name and leaves the image data alone, so the picture is identical. Your system may warn that the file could stop working, but that doesn't apply here because both extensions mean the same format. Q: Why do both .jpg and .jpeg exist? A: Older versions of Windows only allowed three letters in a file extension, so .jpeg was shortened to .jpg. Other systems kept the four-letter spelling, and both stayed in use. Q: Is the JPEG to JPG converter free? A: The JPG download in Edit Studio costs no credits, and accounts are free. The separate Convert tool costs 0.3 credits per image, and a new account gets 25 credits on sign-up, enough for 83 conversions. Files carry no watermark. Q: Does re-saving in Edit Studio change the image? A: The pixel size stays the same, but the JPG download encodes the image again at high quality, so it isn't a bit-for-bit copy. It also leaves out metadata such as camera details and location. If you want the file untouched, rename it instead. Q: Can I rename a PNG to JPG? A: No. A PNG holds different data, so renaming it only gives you a misleading extension, and some apps will refuse to open it. Open the PNG in Edit Studio and download a JPG, which really converts it. Transparent areas turn white. Q: How do I change JPG to JPEG? A: Rename the file from .jpg to .jpeg. Edit Studio always saves the .jpg spelling, so renaming is the way to get .jpeg. Q: Can I convert many JPEG files at once? A: Not in Edit Studio, which works on one image at a time. To rename a folder, use the Windows command or the Finder option shown on this page; neither one uploads your files. Q: Are my files uploaded? A: Renaming happens on your own device, so nothing is uploaded. To use Edit Studio you do upload the image to your account. If it's private and only the extension is wrong, rename it instead. ## Related pages - JPG to PDF: https://kenerateai.com/jpg-to-pdf - AVIF to JPG: https://kenerateai.com/avif-to-jpg - WebP to PNG: https://kenerateai.com/webp-to-png - PNG maker: https://kenerateai.com/png-maker - Image cropper: https://kenerateai.com/image-cropper - Upscale image: https://kenerateai.com/upscale-image - AI image editor: https://kenerateai.com/ai-image-editor ## Sources - Kenerate Edit Studio: https://kenerateai.com/app/edit - MDN — Image file type and format guide: https://developer.mozilla.org/en-US/docs/Web/Media/Guides/Formats/Image_types - JPEG committee — Overview of JPEG: https://jpeg.org/jpeg/ - Trusted Reviews — JPG vs JPEG: What's the difference?: https://www.trustedreviews.com/explainer/jpg-vs-jpeg-whats-the-difference-4399807
