JPG to JPEG Converter
Convert JPG images to JPEG entirely in your browser. JPG is lossy compression, ideal for photos, no transparency; JPEG is same format as JPG; the formal extension and MIME spelling. The conversion runs locally using the Canvas API — your file is decoded, re-encoded, and offered as a download without ever touching a server.
How to use
- Drop your JPG file onto the dropzone (or click to browse).
- The converter decodes the source image entirely in your browser using the Canvas API.
- If the target format supports it, you can adjust quality before encoding.
- Click Download to save the JPEG file to your device.
