How to compress images without losing quality
Upload your JPG, PNG, or WebP file by dragging it into the drop zone or clicking to browse. Choose a compression level that balances file size and visual clarity — ideal for email attachments, websites, and social media. Click "Compress image" to optimize your photo. The smaller file downloads instantly to your device.
All compression runs locally in your browser using the Canvas API. Your photos are never uploaded to a server, which keeps personal snapshots, product shots, and client assets private and secure.
