FAQBuilt for quick, private file work
The platform is deliberately browser-first: simple for users, explicit about support, and lightweight to operate.
Are my files uploaded to a conversion server?+
For the browser-first converters currently available on ConvertAnyFile, supported files are processed on your device. The live Image, Data, Archive, and Subtitle categories do not require source-file contents to be uploaded to a ConvertAnyFile conversion server.
Do I need an account?+
No. The core browser converters are designed to work without registration, sign-in, or a cloud project.
Can I convert multiple files at once?+
Yes. The shared batch workspace provides per-file status, individual downloads, append-by-drag, failure isolation, and ZIP download for successful results. Category-specific limits still apply.
Why are there batch limits?+
Local conversion uses the memory and CPU of your device. Each category defines limits that reduce the chance that unusually large files, expanded archives, decoded images, parsed data, or pathological cue counts make the browser tab unstable.
What happens if one file fails?+
A failed file does not stop the rest of the batch. Retry is only offered for failures that may recover; deterministic invalid or unsupported files are not placed in a pointless retry loop.
Can I cancel a conversion?+
Yes. Cancelling resets the active category engine. Results that already finished remain available, and unprocessed files can be converted later.
Does ConvertAnyFile change my original file?+
No. Conversion creates a new downloadable output. Your original local file is not overwritten by the website.
Why can the first conversion take longer?+
Some categories start a browser worker or load a WebAssembly engine only when needed. First use can include engine startup and caching work; later conversions in the same environment may start faster.
Which converter categories are available?+
Images, structured Data, Archives, and Subtitles are live. Subtitle supports SRT, VTT/WebVTT, ASS, SSA, and SBV input; SRT, VTT, SBV, and TXT output; full-file preflight analysis; timing-shift controls; formatting cleanup; and transcript export options.
Why not process every file type on a server?+
Server conversion can be useful for heavy or specialized workflows, but it adds upload time, temporary storage, cleanup, and infrastructure cost. ConvertAnyFile prefers browser-first processing when the user experience and fidelity contract can be made dependable.
