Frequently Asked Questions & Guides
How does ChameLeo convert files without uploading them to a server?Help Center
ChameLeo executes conversion pipelines directly on your device using WebAssembly (WASM) and browser Web Workers. Tools like FFmpeg and PDF processors are compiled to run within your browser's sandboxed engine. Your files never travel across the internet, ensuring total confidentiality and near-instant processing.
Why did a large video or document conversion fail or crash the tab?Help Center
Because processing happens client-side, the browser allocates memory from your device's physical RAM. If a file is very large (e.g., a 2GB 4K video) or your system is low on free RAM, the browser tab may exceed its memory quota. To resolve this: close background tabs and applications, convert files in smaller batches, or compress files prior to conversion.
Do I need to create an account or sign up to convert files?Help Center
No! ChameLeo requires zero registration, no login credentials, and no email address. You simply open the converter, select your file, and download the converted output immediately without any friction.
Can ChameLeo convert DRM-protected or password-locked files?Help Center
No. Files encrypted with Digital Rights Management (such as FairPlay, Widevine, or PlayReady) or protected with cryptographic passwords (such as encrypted PDFs or ZIPs) cannot be decrypted or converted by ChameLeo. Circumventing digital locks is strictly prohibited.
Which web browsers and operating systems are supported?Help Center
ChameLeo works on all modern web browsers that support WebAssembly, including Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, Brave, and Opera across Windows, macOS, Linux, Android, and iOS. For optimal performance with large media files, desktop Chrome or Edge is recommended.
Are there artificial daily conversion limits, hidden subscriptions, or watermarks?Help Center
None at all. ChameLeo is 100% free with no daily limits, no file count quotas, no watermarks, and no subscription tiers. You can convert as many files as your device hardware can comfortably process.
What should I do if an input file displays a 'corrupted header' or 'unsupported format' error?Help Center
This typically occurs when a source file is incomplete (such as a partially downloaded MP4 missing its 'moov atom' index) or uses an experimental codec. Verify that the file plays properly on your local media player, try re-saving or re-exporting it in its original application, and ensure the file extension matches the actual format content.
Where are my converted files stored on my device and when are they deleted?Help Center
Converted files in ChameLeo are never written to any remote server or external disk. They reside strictly in your browser's temporary memory (RAM) as volatile local Blob objects. When you click download, the file is saved directly to your local storage; the instant you close the browser tab or refresh the page, the allocated memory buffer is completely purged.
Can ChameLeo view the contents of my files or collect telemetry/data?Help Center
No. ChameLeo is engineered around a strict zero-upload architecture. Because the conversion engine runs entirely inside your browser's local sandbox via WebAssembly, it is technically impossible for our servers or any third party to view your files, EXIF metadata, or conversion history. No user telemetry, tracking cookies, or behavioral profiling are collected.
