JPEG and JPG: The Same Thing

Here's a secret: JPEG and JPG are the exact same format. The only difference is the file extension length-.jpeg (4 letters) vs .jpg (3 letters).

This matters because some software only accepts one extension. If a website or application rejects your .jpeg file but accepts .jpg, conversion solves it instantly.

How to Convert JPEG to JPG

Upload your JPEG file - Select your .jpeg image
Confirm JPG output - The file is renamed to .jpg extension
Download your file - Same image, different extension

Conversion is instant-we're essentially just renaming the file.

Why This Matters

Historical Reason

Old Windows (before Windows 95) only allowed 3-character extensions. JPEG became JPG. Modern systems support both, but the legacy persists.

Software Compatibility

Some older or specialized software only recognizes .jpg files. Upload forms may specifically require .jpg extension.

Consistency

If you're organizing a photo collection, having all files with the same extension keeps things tidy.

What's NOT Different

Quality - Identical. No compression, no changes
File size - Same down to the byte (except extension)
Compatibility - Both work in all modern software
Format - Technically the same JPEG/JFIF format

Think of it as renaming "document.jpeg" to "document.jpg"-the content is unchanged.

Common Reasons to Convert

Upload Requirements

A form specifies ".jpg files only" but your images are .jpeg. Quick conversion makes them acceptable.

Software Requirements

Old photo software or games may only recognize .jpg extension. Converting resolves the issue.

Batch Renaming

Standardizing a photo collection where some files are .jpeg and others are .jpg.

Reverse Direction

Need the opposite? We can also convert JPG to JPEG if your software requires the longer extension.

Works on Any Device

Convert JPEG to JPG in your browser:

Windows, Mac, Linux, Chromebook
Chrome, Firefox, Safari, Edge
iPhone, iPad, Android

Pro Tip

Before converting many files, try just renaming one file's extension manually. If that works in your software, you can batch rename without a converter.

Common Mistake

Thinking JPEG is higher quality than JPG or vice versa. They're identical. The extension is just a naming convention, not a quality indicator.

Best For

Resolving upload form restrictions, working with legacy software that only recognizes .jpg, and standardizing file extensions in photo collections.

Not Recommended

Don't bother converting if your software accepts both extensions. Modern applications universally support .jpeg and .jpg interchangeably.

Frequently Asked Questions

No difference in format or quality. JPEG and JPG are the same format with different extension lengths. JPG became common because old Windows only allowed 3-character extensions.

Poor programming. Well-designed sites accept both. If a site only checks for .jpg extension, your .jpeg file is rejected despite being identical.

No. The image data is unchanged. We're effectively renaming the file extension, not recompressing the image.

Usually yes. Changing '.jpeg' to '.jpg' in the filename typically works. Our converter does this reliably with proper file handling.

JPG is more common and slightly more compatible with old software. JPEG is technically more correct. For new projects, either works.

No. The file size remains identical because the image data isn't changed, only the extension.

DOS and early Windows limited extensions to 3 characters. JPEG had to be shortened to JPG. Modern Windows supports both, but JPG stuck.

Varies by camera. Most use .jpg for compatibility, but some use .jpeg. Either is correct.
