What is the Compress Image?
BYAFT's Compress Image tool reduces the file size of a JPG, PNG or WebP photo, right in your browser. Choose an output format and a quality level, and the tool shows the before-and-after size so you can find the sweet spot — no sign-up, no watermark, and nothing uploaded to a server.
It is the quickest way to make a photo small enough to email, attach or upload without a noticeable drop in quality.

Frequently asked questions
Is the image compressor free?
Yes. Compressing images with BYAFT is completely free, with no sign-up and no watermark.
Are my images uploaded anywhere?
No. The tool runs entirely in your browser and your images never leave your device.
Which formats can I compress to?
You can compress to WebP or JPG, both of which are lossy and give real size savings. WebP is usually the smallest.
Will I lose quality?
There is some quality trade-off because compression is lossy, but you control it with the quality slider and can check the result size before downloading.
