Compress Image to KB
Find an image that meets your chosen size budget using quality and dimension reduction.
Your result will appear here.
WebP preserves transparency and uses quality adjustment. AVIF is available only if this browser can encode and decode it. PNG is lossless at the chosen dimensions; reaching a target may require smaller dimensions. JPEG fills transparency with your chosen background.
AVIF encoding is unavailable in this browser.
How compress image to kb works
The target uses decimal KB (1,000 bytes). The search tries lower quality before reducing dimensions. The result reports its real size and whether it meets the target.
Choose 100 KB for a 100,000-byte budget. Inspect reduced dimensions before downloading.
