Frequently asked questions
Is this image compressor free?
Completely — no signup, no watermark, no limit on how many images you compress. There is no server doing the work, so there is nothing to charge for.
Are my images uploaded?
No. Compression runs entirely in your browser using the Canvas API. Your images never leave your device.
How much smaller will my images get?
It depends on the image and your quality setting — photos often shrink 60–90% at 70–85% quality with no visible difference. The tool shows the exact savings for each file.
Will it reduce quality?
You control it. JPG and WEBP are lossy, so lower quality = smaller file. PNG is lossless. You can preview the size trade-off instantly with the slider.
Can I resize at the same time?
Yes — pick a maximum dimension (e.g. 1920px) and images are downscaled before compressing, for even smaller files.
