Reduce Image Size Under 100KB
To reduce an image under 100KB, combine smaller dimensions with stronger compression and check the final preview.
Start With Image Dimensions
Most oversized files come from dimensions that are much larger than the final use. Resize the image before lowering quality so the result stays cleaner.
For websites, a maximum width around 1600 to 2000 pixels is enough for most content images.
Balance Quality And File Size
A quality setting around 70 percent is a strong starting point for JPG photos. Increase it when you see artifacts, and lower it when file size matters more.
Always compare the preview and file size after compression instead of guessing from the slider alone.
When 100KB Is Required
Upload forms and application portals often set strict limits. If your image is still too large, lower the maximum width and then compress again.
For document photos, keep the face and text clear even when pushing toward a smaller file size.
