A: There's a new "Convert files offline instead of online" option below the conversion button. This option works on most image, video and audio formats, it doesn't work on document formats yet. If this option is selected, your files will be converted offline by Javascript or WebAssembly in web browser on your local device. WebAssembly is a type of code that can be run in modern web browsers - it is a low-level assembly-like language with a compact binary format that runs with near-native performance and provides languages such as C/C++, C# and Rust with a compilation target so that they can run on the web. It is also designed to run alongside JavaScript, allowing both to work together.
Note that the offline converter only works on web browsers that support new technologies such as ES Modules, WebAssembly, Shared Array Buffer and Site Isolation. We recommend using the latest web browsers and operating systems.
This option is unselected by default, you should select it if:

Q: What does "Always use open-source projects to convert documents" option mean?A: Although all files can be converted by open-source projects, we reserved some conversions processed by the developers' official software. For example, your Word, Excel or PowerPoint files will be converted by Microsoft Office Word, Excel or PowerPoint software by default.

The history file list is stored as "Local Storage" in your web browser only, it will not be exposed outside of your current web browser. You can remove history by clicking the "Delete all files" button which can be found in most pages.
Q: Why did my conversion fail?A: Most conversion failures are caused by server overload. The allocated server's CPU or memory is currently 100% occupied so it doesn't have enough resources to complete your conversion. You can try it again a few minutes later if this happens. There are also many other reasons that may cause conversion failure, for example: the source file is not supported, corrupted, encrypted with password or Digital Rights Management (DRM). If your conversion fails, you can click the "Why it failed?" button next to your file to check out the exact reason.
