Why this tool is different
Unlike most online compressors, this tool does everything inside your browser. Your images are never uploaded to any server, so they stay completely private and the compression is instant.
How to compress an image
- Choose your output format (WebP gives the smallest size).
- Set the quality and, optionally, a maximum width.
- Drag and drop your images, or click to upload.
- Download each compressed image, or use Download all.
WebP vs JPEG vs PNG
WebP usually gives the smallest file size and is supported by all modern browsers. JPEG is great for photos. PNG is lossless and best when you need transparency, though the file size is larger.
