Frequently Asked Questions

This image compressor runs entirely in your browser using HTML5 Canvas and modern web APIs. It reads your image, re-encodes it at your chosen quality level, and generates a new optimized file. Because everything happens locally, your images never leave your device — making it both fast and completely private.

The compressor supports PNG, JPG (JPEG), GIF, and WebP formats. PNG compression works well for screenshots and graphics with text. JPG compression is ideal for photographs and complex images. WebP offers better compression than both PNG and JPG for most use cases.

Some quality loss is inevitable with lossy compression (JPG, WebP), but at quality settings of 70-85%, the difference is usually imperceptible to the human eye while file sizes can be reduced by 50-80%. For PNG images, compression is lossless and preserves perfect quality. Use the side-by-side preview to find the right balance for your needs.

No — all compression happens entirely in your browser using client-side JavaScript. Your images never leave your device, are never uploaded to any server, and are never stored anywhere. This ensures complete privacy for sensitive images (documents, screenshots with personal data, etc.).

For website images, use quality 70-80% for JPG photos (good balance of quality and file size) and PNG for screenshots and UI elements (lossless). For email attachments, quality 50-60% works well. For social media, quality 80-90% preserves more detail. The goal is to keep individual images under 200KB for fast page loading.
