Frequently asked questions

How much can I compress an image without losing quality?

Most JPG images can be compressed 50-80% with no visible quality loss using our smart quality detection. PNG files typically achieve 20-40% reduction with lossless compression.

Is there a file size limit?

No. AmberPic processes everything in your browser, so there are no server-side limits. You can compress images of any size, from icons to high-resolution photos.

Are my images uploaded to a server?

No. All compression happens locally in your browser using WebAssembly. Your images never leave your device, ensuring complete privacy.

What's the difference between lossy and lossless compression?

Lossy compression reduces file size by removing some image data that humans can't easily perceive (slight color shifts, fine details). Lossless compression preserves every pixel but achieves smaller reductions (typically 10-30%).

Can I compress images in batch?

Yes. Upload up to 100 images at once and compress them all with the same settings. Download individually or as a ZIP file.
