Image Compressor — FAQ
- Does compressing an image upload it?
- No. All compression happens inside your browser. Your images are never uploaded.
- What is the best format for compressed web images?
- WebP gives the best compression-to-quality ratio for web use. JPEG is a good alternative for photos when WebP is not an option.
- How much can I reduce file size?
- Converting a high-quality JPEG to WebP at quality 80 typically reduces size by 25–40%. PNGs can shrink even more.
- Can I resize images while compressing?
- Yes. Set a Max Width or Max Height in the settings. The image will be scaled down proportionally before compression.
