FAQ
Will compressing reduce image quality?
Some quality is traded for a smaller file size. "Low" compression is visually lossless for most photos; "Extreme" is best for thumbnails or when file size matters most.
What's the difference between this and the Resizer?
This tool keeps the original pixel dimensions and reduces quality/format overhead. Use the Image Resizer if you also need to change width/height.
Need an exact file size like 100KB?
Use Compress Image to Exact KB to automatically hit a target size.
