FAQ

Is the Image Compressor free?

Yes — 100% free, no login, no watermark. All compression happens in your browser.

What quality should I use?

For social media, 70-80% quality is a good balance between file size and visual quality. For web thumbnails, 50-60% is often enough.

Does it support batch compression?

Yes, upload as many images as you want. They're all compressed at the same quality setting, and you download them as a single zip.

Will compression reduce the resolution?

No — the compressor only adjusts quality (JPEG/WebP compression level), not dimensions. Your images stay the same size in pixels.
