How to Convert JPEG Files to JPG
- Upload your files by dragging and dropping them onto the converter or clicking to browse. You can mix different formats - JFIF, JPE, JPEG, and JPG files can all be converted together.
- Adjust quality settings using the slider or presets. Lower quality means smaller files, higher quality preserves more detail. The default (92%) works well for most uses.

- Download your JPG files individually or as a ZIP archive (automatically created when you have more than 2 files).

Frequently Asked Questions
They're all the same image format - JPEG compression - just with different file extensions. JPG became popular in the DOS era when extensions were limited to 3 characters. JFIF (JPEG File Interchange Format) is the technical standard name. JPE is an alternate extension used by some older software. For a detailed explanation, see our guide on why these different names exist.
For most purposes, 80-92% provides excellent results. Use lower quality (60-75%) when file size is critical, like thumbnails or web optimization. Use higher quality (95-100%) for professional printing, archival, or when preserving maximum detail is important.
Yes, manual renaming works since the file contents are identical. However, our converter offers advantages: batch processing multiple files, quality adjustment to reduce file size, and ensuring proper JPEG headers. Plus it's faster than renaming files one by one.
No. This converter works 100% in your browser using JavaScript. Your files are processed locally on your device and never uploaded to any server. This makes it safe for private, sensitive, or confidential images.
Chrome and Edge use Windows system file associations when saving images. If your Windows registry has JPEG images associated with the JFIF extension (often set by older software or registry cleaners), browsers will use that extension. You can fix this permanently by editing Windows registry settings, or simply use this converter.
When you convert more than 2 files, the ZIP archive includes all your converted JPG files plus a details.txt file with conversion information - original sizes, converted sizes, quality settings used, and size savings for each file.
