Shrink videos for WhatsApp, email and uploads using your computer's built-in hardware encoder, so it is fast even for long clips, and the file never leaves your device.
Boltly runs entirely in your browser. Your files are processed on your own computer and are never uploaded, so it is safe for IDs, contracts and family photos, and it keeps working offline once loaded.
A 1080p phone video often drops by 70-90% with the Balanced preset at 720p.
No, never.
No. Your computer's own encoder does the work in the browser.
