About JPG format

JPEG is the most widely used image format for photographs and complex images. It uses lossy compression to achieve small file sizes while maintaining acceptable visual quality. Perfect for sharing photos online, JPEG balances quality and file size better than any other format for photographic content. Nearly every device and application supports JPEG.

Pros

  • +Small file sizes ideal for web and sharing
  • +Universal compatibility across all devices
  • +Adjustable compression for quality/size balance

Cons

  • -Lossy compression reduces image quality
  • -No transparency support
  • -Quality degrades with each save

About JPEG format

JPEG (Joint Photographic Experts Group) is identical to JPG - the different extension is simply a historical artifact from early file system limitations. Both formats use the same compression algorithm and produce identical results. JPEG remains the standard for digital photography and web images due to its excellent compression and universal support.

Pros

  • +Identical to JPG with universal support
  • +Efficient compression for photographs
  • +Widely recognized file extension

Cons

  • -Same limitations as JPG (lossy, no transparency)
  • -Some older systems prefer .jpg extension
  • -Quality loss with repeated editing

Frequently asked questions

Is it safe to convert JPG to JPEG online?↓
Yes, Convt processes your files entirely in your browser using WebAssembly. Your files never leave your device - no data is uploaded to any server. This makes it completely private and secure.
How long does JPG to JPEG conversion take?↓

Is there a file size limit for conversion?↓

Do I need to install any software?↓
No installation required. Convt runs entirely in your web browser. It works on any modern browser including Chrome, Firefox, Safari, and Edge on desktop and mobile devices.
Can I convert multiple files at once?↓
Yes, you can add multiple files to the converter and process them all. Each file will be converted individually and you can download them separately or together.
Will converting JPG to JPEG reduce image quality?↓
JPEG uses lossy compression, which may slightly reduce quality in exchange for smaller file sizes. For most uses, this difference is imperceptible.
