JPG is common for photos and web images.
JPG is widely supported for photos and sharing.
Create a fresh JPEG copy when a site or workflow requires that exact extension. JPG and JPEG are the same image format, so this is mainly a compatibility step.
The output keeps the original pixel size.
The image is re-encoded, so converting between JPG and JPEG does not add detail or improve quality.
The work runs in your browser on your device while you wait.
JPEGConvert.com keeps the workflow simple: upload, convert, and download. For the best results, start with the highest-quality source file you have.
