Frequently Asked Questions
Are my files uploaded to your servers during conversion?
No, absolutely not. All conversion routines (images, documents, video, data) execute locally inside your browser sandbox via compiled WebAssembly (WASM) and WebGPU. Your files are processed entirely in-memory and never leave your physical device.
How does the File Share tunnel work and how long are files kept?
When you explicitly choose to "Share" files, the encrypted binary chunks are stored on temporary transfer nodes with an expiration you choose (up to 7 days). Once expired, automated daemons permanently overwrite and scrub the files from disk.
What file formats and sizes are supported?
SendUrFile supports over 100+ formats across Images (HEIC, WebP, AVIF, PNG, JPG, SVG), Documents (PDF, DOCX, TXT, EPUB), Audio/Video (MP4, MP3, WAV, WEBM), and Data (CSV, JSON, XML, SQL). Free tier supports up to 50 MB in RAM; Pro tier extends capacity up to 2 GB.
Can I use SendUrFile offline without an internet connection?
Yes! Once the web application and WASM modules are cached in your browser, you can disconnect your internet connection and convert files completely offline with zero data loss.
