FAQ
Frequently Asked Questions
How does Auto DarkEdit work?
It's an online editor that processes videos and images in bulk right in your browser, using Canvas and FFmpeg WebAssembly. You add the files, configure watermark, logo, text or layout, and the system renders everything in parallel.
Is the processing online?
The access is online, but processing is 100% local in your browser. Your files never leave your computer — nothing is sent to any server.
Are my files safe?
Yes. Because all processing happens on your device, the files stay private. We do not store videos or images.
Can I edit hundreds of videos?
Yes. Auto DarkEdit was built for bulk editing, with parallel processing based on your CPU cores.
Can I edit hundreds of images?
Yes. The batch image editor accepts hundreds of files with custom watermark, logo, text, rotation, opacity and positioning.
Do I lose quality?
No. We render in H.264 with high bitrate for videos and keep the original resolution of your images, preserving the audio in videos.
Do I need to install anything?
No. It runs right in the browser. No installs, no plugins, no app downloads.
Does it work on Windows?
Yes, it works on any Windows PC using an up-to-date Chrome, Edge, Firefox or Brave.
Does it work on Mac?
Yes. Compatible with macOS via Safari, Chrome or Firefox.
Does it work on Linux?
Yes. Any Linux distribution with a modern browser is supported.
How do I download the files?
When processing ends, you can download each file individually or grab everything in a single ZIP.
Is there a size limit?
The limit is your device's available memory. Because processing is local, more powerful computers handle larger batches.
How does batch processing work?
The system splits the batch into parallel tasks using OffscreenCanvas and Web Workers, using every CPU core to render faster.
