Frequently Asked Questions
Typical compression reduces file size by 40-80% depending on the image content, format, and quality setting you choose. Photos with smooth gradients compress more aggressively than detailed graphics, and PNG screenshots can shrink by 70% or more without visible quality loss.
Some quality loss occurs with lossy compression, but at 80-90% quality the difference is imperceptible to the human eye. Our compressor lets you adjust the quality slider so you can balance file size against visual fidelity, and you can preview the output before downloading.
Smaller images load faster, which directly improves website performance, Core Web Vitals scores, SEO rankings, and user experience. Page weight is one of the biggest factors in mobile load times, and compressing images is the single most effective optimization for most websites.
Our image compressor supports the three most common web formats: JPG/JPEG (best for photographs), PNG (best for graphics with transparency), and WebP (modern format with superior compression). All processing runs locally in your browser using the Canvas API, so your images are never uploaded to any server.
