Unlike conventional online tools that upload your files to remote servers, Shrinkify processes everything inside your browser tab. Files are read into memory, transformed using WebAssembly and Web Workers, then exported directly to your Downloads folder. No round-trip. No server queues.
Drop or pick your file. It stays on your device — the browser reads it locally through the File API without any network request.
WebAssembly modules (FFmpeg, PDF-lib, Canvas) run the operation on your CPU. A background Web Worker keeps the UI responsive during heavy tasks.
The finished file is generated as a browser Blob and saved to your disk. Zero upload latency means results are available the moment processing completes.
There is no server endpoint to intercept. Your photos, contracts, and audio stay on your machine — making Shrinkify safe for GDPR-sensitive, medical, or legal documents without any additional compliance steps.
A 50 MB video takes 10+ seconds just to upload on most connections. With local WASM processing, you skip that entirely. The only speed limit is your CPU — and modern browsers are fast.
No. Every tool works immediately — no signup, no paywall, no watermarks. Open the page and start processing.
There are no artificial limits. Since processing runs on your device, the practical ceiling is your browser's available memory (typically 1–4 GB). For very large files, close other tabs to free up RAM.
Your files never leave your computer. There is no upload step, no server-side processing, and no data retention. The entire pipeline runs inside your browser tab using WebAssembly.
