Image Compress FAQ
How much can I compress an image?
JPG and WebP images can typically be reduced 50-80% with minimal visible quality loss by adjusting the quality setting. PNG files use lossless compression, so size reduction is smaller but quality is fully preserved.
Are my images uploaded to a server?
No. All compression happens in your browser using the Canvas API. Your images never leave your device. This is safe for sensitive or confidential images.
What quality should I use?
For web use, 75-85% quality is a good balance between size and visual quality. For photos where quality matters, use 90%+. For thumbnails or preview images, 60% is often acceptable.
Does it support batch compression?
Yes. You can select multiple images at once. Each image is compressed independently with the same quality setting, and you can download them individually or all together.
