How do I convert JPG to JPEG using LetsConvert?

Go to the JPG to JPEG converter page, upload your JPG file by dragging it into the upload area or clicking 'Choose File'. Select 'JPEG' as the output format, then click 'Convert'. The tool re-encapsulates your image as a .jpeg file without re-encoding, so the conversion is instant. Download the converted file to your device. For batch conversion, you can upload multiple JPGs at once—all are processed in parallel.

Why should I convert a JPG file to JPEG?

JPG and JPEG are essentially the same lossy image format defined by the ISO/IEC 10918 standard. The only difference is the file extension: .jpg is used for older 8.3 filename systems, while .jpeg is required by some modern applications, web servers, or embedded devices that strictly check the extension. Converting ensures your image is accepted by those systems without altering the pixel data or file size. Use it when uploading to legacy CMS, certain cloud storage, or email attachments that block .jpg files.

What happens to my image data when converting from JPG to JPEG?

Our JPG to JPEG conversion is a direct container remux—the original JPEG bitstream, EXIF/XMP metadata, ICC color profile, and resolution are copied as-is. Since JPG and JPEG share the same format, there is zero recompression, so no quality loss occurs. The conversion preserves all pixel data, including edit history, quantized DCT coefficients, and any embedded thumbnails. It does not affect layers (JPG/JPEG has no layers) or transparency (JPEG does not support an alpha channel; convert to PNG if you need transparency).

JPG-TO-JPEG

Converting JPG to JPEG just renames the extension; both are identical lossy formats. Our tool preserves all pixels and metadata exactly.
