Most online tools force you to upload your sensitive files to a remote server. We took a different approach. SwiftCompress uses advanced WebAssembly to optimize your files entirely inside your own browser.
Your photos, confidential documents, and personal videos never touch our servers. Processing happens in your local RAM.
No waiting for heavy files to upload or download. The compression begins the very second you select your file.
Completely free to use. No sign-ups, no watermarks, and no artificial daily limits blocking your workflow.
