Choosing the Right Compression Quality

Compression quality determines how much image information is retained when creating JPG or WebP output. A higher quality level generally preserves more visual detail but may produce a larger file. A lower quality level can create a smaller file while potentially reducing visible detail.

For most everyday images, the recommended high-quality setting provides a useful balance between visual quality and file size.

Image Compression Examples

Website Images Reduce large image files before adding them to a website to help improve page loading performance.

Email Attachments Compress photos and graphics to make email attachments smaller and easier to send.

Social Media Reduce image file sizes before sharing images online or uploading them to social platforms.

Why Compress Images?

Large image files can consume more storage space and may take longer to transfer over slower internet connections. Compressing images can make files easier to store, send, upload and share.

Website owners can also benefit from properly optimized images because smaller image resources can contribute to a more efficient browsing experience.

Browser-Based Image Compression

STAAMS processes images locally using your web browser. This means the compression process can be performed without sending the original image to a STAAMS server.
