Which image formats are supported for compression?

You can compress JPEG/JPG, PNG, and WebP images individually or in batch.

Does compressing my images lower the image resolution?

By default, our image compressor optimizes compression ratios and removes redundant metadata without resizing dimensions, ensuring sharp details.

Are my uploaded photos safe and private?

Yes, completely. LutaTech Image Compressor operates 100% within your web browser using HTML5 Canvas and WebAssembly. Your photos are never uploaded or transmitted to any server.

What is the best format for website images?

WebP is currently the recommended format for modern websites. It provides 25%–35% smaller file sizes than comparable JPEG or PNG images while supporting both transparency and high-definition photography.

Is there any file size limit?

Because compression is performed directly in your browser using your local device memory, you can compress images of any size, including massive 40+ megapixel camera RAW/JPEG photos.

Everything you need to know about Image Compressor on LutaTech.

No, by default our compressor maintains the exact pixel width and height of your original photos. It achieves smaller file sizes by optimizing color encoding and stripping unnecessary camera metadata (EXIF).
