Upload an image to start compressing

Many educational platforms and government sites require uploads to be under 100KB or 200KB. Our JPG compressor gives you a slider to choose the exactly maximum MBs or KBs you need, guaranteeing your file fits the requirements perfectly.

常见问题解答

压缩 图片?
✓ 70-80% quality = 60-80% smaller file size with zero visible artifacts.
Lossy vs Lossless?
Lossy compression (JPG, WebP) permanently removes some image data to achieve smaller files. Lossless compression (PNG) reorganizes data without any quality loss. For photos, lossy is usually fine; for logos with text, use lossless.
Batch 压缩?
Currently you compress one image at a time to give you full control over quality preview. The entire process takes under 5 seconds per image.
Dimensions change after 压缩?
✓ 压缩 only reduces byte weight; pixel dimensions remain identical.
