Compress Images

Reduce JPG, PNG, and WebP file size — free, no signup, no watermark, no uploads. Your files never leave your device.

How to Compress Images Without Losing Quality

Large image files slow down websites, fill up storage, and make sharing frustrating. This tool compresses JPG, PNG, and WebP files directly in your browser — no upload required, no account needed, and your files never leave your device.

What does "target max size" mean?

The slider sets a target ceiling per file. The compressor will reduce quality and strip metadata to fit under that threshold. If your file is already smaller, it won't be touched. Results may vary depending on image content — photos compress much better than screenshots or graphics with large flat areas.

JPG vs PNG vs WebP

JPG is best for photos — it uses lossy compression and produces the smallest files. PNG uses lossless compression and is better for screenshots, logos, or anything with text and sharp edges. WebP supports both, and typically produces 25–35% smaller files than JPG at equivalent quality.

Frequently Asked Questions

+Are my images uploaded to a server?

No. Compression runs entirely in your browser using WebAssembly. Your files never leave your device.

+What image formats are supported?

JPG, JPEG, PNG, and WebP. For HEIC files, use our HEIC to JPG converter first.

+Will the compressed image look different?

At the default 1 MB target, the quality difference is virtually invisible for most photos. You can raise the limit to preserve more quality.

+Can I compress multiple images at once?

Yes. Drop as many images as you need — they are processed one by one and you can download all at once as a ZIP.
