How to Compress JPG Images Online

Use JPGResize to reduce a JPEG file size in your browser. Adjust compression quality and review the compressed preview before downloading.

Upload your JPG. Choose a JPG or JPEG from your device, or drag it into the upload box.
Set the compression quality. Select Compress and adjust the quality slider. Lower values usually create smaller files, while higher values retain more detail.
Preview and download. Select Compress to review the output size, then Export to save your compressed JPG.

Need to change pixel dimensions too? Use Resize first; smaller dimensions can further reduce the final file size.
