Frequently asked questions
Free Image Compressor — Reduce File Size Without Quality Loss
Large image files slow down websites, get rejected by email attachment limits and eat up storage. This free image compressor reduces file size by up to 80% while keeping images sharp — all processed in your browser with no upload required.
How it works: The compressor uses the browser's Canvas API to re-encode your image at a quality setting you control. For photos (JPG and WebP), this reduces file size dramatically with minimal visible difference. For graphics with flat colours (PNG), compression is more modest but still meaningful.
Quality slider guide: 80% quality (the default) is recommended for most uses — most people cannot see any difference from the original. Drop to 60-70% for smaller files with acceptable quality. Use 90%+ when pixel-perfect quality is critical.
Best for: Compressing photos before uploading to WordPress, Shopify or Ghost CMS; reducing product images for an online shop; shrinking photos before attaching to an email; reducing storage used by a large photo library.
Supported formats: JPG, JPEG, PNG and WebP. Files up to 20MB work comfortably on most devices.
Privacy: Your image is processed using the Canvas API entirely in your browser. Nothing is uploaded to any server. The compressed version downloads directly to your device and your original file is never modified.
