Compress PDF for IRCC Under 4MB

Processing Architecture & Calibration

Drop immigration application PDF to compress under 4MB All media streams are isolated locally inside your device using hardware-accelerated WebAssembly (WASM) and WebCodecs. Zero bytes of audio or video content are ever transmitted to external cloud servers.

How It Works

1. Drop your audio or video file directly into the browser dropzone.
2. The client-side engine executes local inference or bit-exact extraction without upload delays.
3. Audition the 15-second realtime A/B comparison with the Dry/Wet slider.
4. Export your pristine clean master file with 100% original video track preservation.

How does in-browser AI noise reduction work?

Drop & Clean executes compiled WebAssembly (WASM) neural networks locally on your CPU/GPU threads inside the browser sandbox. The raw audio stream is demuxed, processed frame-by-frame via 48kHz ERB filterbanks, and recombined with your video without sending a single byte over the network.

Will my 4K/HDR video lose quality during export?

No. Drop & Clean features bit-exact video passthrough using WebCodecs and the built-in Media Service. Only the audio track is extracted and cleaned; the video stream (including 4K/8K resolution, 60fps frame rate, and HDR color metadata) remains 100% untouched without lossy re-encoding.

What is the difference between Express ⚡ and Pro 🚀 modes?

Express Mode is powered by our ultra-fast 48kHz engine (RTF ~0.08, ~1.2s per 15s preview), ideal for everyday wind, air conditioning, and room hum. Pro Mode runs DPDFNet 48kHz (RTF ~0.47, ~7s per 15s preview) with deeper ERB filterbank suppression for heavy background chatter and harsh reverberation.

Is Drop & Clean free to use?

Yes. All 15-second A/B audition previews are 100% free with unlimited comparisons. Active users receive +10 free export credits every 7 days, and you can purchase permanent credits or subscribe for unlimited high-volume exports.

Are my files private and secure?

Completely. Because all computations happen client-side inside your browser sandbox, neither Drop & Clean nor any third party can access, listen to, or store your audio/video files. It is 100% GDPR and CCPA compliant by design.
