Got Questions?

Here is everything you need to know about our compressor.

Yes, completely free. There are no hidden fees, subscriptions, or watermarks placed on your final image.
No. The entire compression process happens locally within your web browser. We never see, save, or store the files you select, making it safe for personal documents.
You can upload most standard image formats including JPG, PNG, and WebP. The final downloaded file will be provided as a highly optimized JPEG.
To reduce the file size, our tool automatically lowers the image quality setting slightly. For very large images, it may also scale down the physical dimensions. We carefully balance this to keep the image looking as clear as possible while meeting the strict 300 KB limit.
The tool will recognize that the image is already small enough and will immediately format it for download without unnecessarily lowering the quality.
Absolutely. The tool is fully responsive and works directly inside your mobile browser on iOS and Android devices, which is great for photos taken straight from your phone camera.
