80% is the sweet spot for web images — most people cannot tell it apart from the original, but files shrink dramatically. Drop to 60–70% for thumbnails and background images where detail matters less. Stay at 90% or above for photography portfolios and product shots where fine texture is the point.
Yes, drop up to 20 files and they process four at a time. Each row shows its own before-and-after size and the percentage saved, so you can see exactly what each file gained. Download them individually or take the whole batch as a single ZIP when it finishes.
Images that are already compressed have little left to remove — a JPG saved at 70% quality will not halve again. Screenshots and flat graphics also resist compression because PNG already handles large uniform areas efficiently. Converting those to WebP usually saves far more than compressing them further.
Yes, Image Compressor is completely free. No signup, no account, and no watermark on outputs. A Pro tier is available for 100 AI ops/day and larger file sizes.
Image Compressor uploads your file over an encrypted connection to our own processing server, converts it, and returns the result. The file is deleted immediately after processing and is never used for anything else. It is not sent to any third party, and we keep no copies.
