Frequently Asked Questions

How do I compress an image to exactly under 100KB?
Upload your image and adjust the quality slider until the output size drops below 100KB. JPEG format typically achieves the smallest file sizes. For large images, resize to smaller dimensions first.
Will my image look bad at 100KB?
For photos under 1000px wide, 100KB is usually enough for good quality at 70-80% JPEG. For larger images, consider resizing down first to maintain visual sharpness.
What file format is best for small file sizes?
JPEG offers the best compression for photographs. WebP is even smaller at the same quality. PNG is best for graphics with text or transparency but produces larger files.
