THE ALMIRA GUIDE
How private browser video conversion works
Learn what local video processing means, what hosting still receives, and how to protect sensitive recordings during conversion.
An encoder can run on your device
A browser application can download a video encoder compiled to WebAssembly and process selected files on your computer. Almira uses ffmpeg.wasm for that work. Selecting a file lets the application read your selection; it does not inherently require an upload. The encoder reads local data, produces an output in browser working memory, and the page prepares a download. CPU time and memory come from your device. This design avoids the need for a remote video conversion API.
Local does not mean zero network requests
You still load the website, scripts, styles, and encoder assets from hosting. Those requests may expose ordinary connection information such as IP address, browser details, requested URLs, and request times to the delivery infrastructure. Almira’s conversion workflow does not send your chosen video to a remote encoder. That distinction matters: a promise that selected media stays local is different from a promise that opening the website creates no network activity. The Privacy Policy explains current practices.
Saved preferences are not a backup
The application remembers preferences such as conversion settings and appearance in local storage. This does not mean your videos, queue, or completed results are backed up online. Reloading or closing the tab can lose active work. Save a finished MP4 to a location you control before leaving. A downloaded file remains on your device until you remove it. The website cannot manage your normal Downloads folder or delete source recordings from your computer.
Protect the device as well as the file
A local converter does not protect against malicious extensions, malware, screen recording, or another person opening your downloads. Use a trusted device for sensitive recordings. Review screenshots and technical logs before sharing them for support: filenames and metadata may reveal information even when the video itself is absent. Clearing browser site data resets saved preferences but does not erase the MP4 you downloaded elsewhere. Manage the downloaded output and original recordings separately.
Advertising would be a separate data flow
The current release does not intentionally include advertising or analytics tags. If such services are enabled later, they may make additional requests and use cookies or identifiers even while encoding remains local. Read the current Cookie Policy for the site’s actual configuration. Local conversion describes how media is processed; it should not be used as a blanket claim about every external service a website might introduce. A future integration requires appropriate disclosure and any applicable consent.
Choose a workflow that fits the recording
Large files can exceed memory, and a sleeping device can interrupt a long task. An offline desktop encoder may be a better fit for large sensitive archives. Browser conversion is useful when the source and available resources fit its limits. Whichever method you choose, preserve backups, process material you have permission to use, and check the completed output before removing originals. The DVD folder guide explains additional limits for disc-based recordings.
