How to convert JPG to JPEG

1. Upload your JPG file

   Click the upload area or drag a JPG image onto it. The file is processed locally — no cloud upload needed.

2. Set quality (optional)

   The Quality slider controls JPEG compression: 80–90 gives a good balance of sharpness and file size. Lower values shrink the file further at the cost of visible artifacts around edges and gradients.

3. Convert

   Press the Convert button. Sharp decodes the JPG and encodes it as a progressive JPEG. If the source has an alpha channel (transparency), it will be flattened against a white background.

4. Download the JPEG

   Click Download to save the .jpg file. JPEG is widely supported for photos and complex imagery. Avoid it for screenshots or flat-color graphics where PNG will compress better.
