常见问题
Is this image compressor really free?
Yes. It's completely free to use with no watermarks, no sign-up, and no daily limits. Compress as many images as you need, as many times as you want.
Are my images uploaded to a server?
No. Compression happens entirely in your browser, on your device. Your images are never uploaded or stored anywhere, so they stay fully private.
What image formats are supported?
The tool supports common web formats including JPG/JPEG, PNG and WebP.
Will compressing my image reduce its quality?
Compression always involves some quality trade-off, but you control the level. At high quality settings, the difference is barely visible while the file size drops significantly. Preview the result before downloading.
Is there a file size or resolution limit?
There's no practical limit for local compression — since nothing is uploaded, you're not restricted by server upload caps. Very large files are processed on your device at full quality.
Can I compress an image to a specific size, like under 20KB?
Yes. Adjust the compression level to shrink your image below a target size like 20KB, 50KB or 100KB. For precise targets, lowering quality or converting PNG to JPG/WebP usually gets you there fastest.
Is my data safe? What happens to my images after compression?
Your images stay on your device the entire time. Nothing is uploaded, stored, or shared — after you close the page, no copy of your file remains on any server.
Why should I compress images for my website?
Smaller images load faster, which improves PageSpeed/Core Web Vitals, reduces bounce rate, and can help SEO rankings. It also saves bandwidth for your visitors and storage costs for you.
