Frequently asked questions

Yes. AllThatConverter processes files using WebAssembly directly inside your browser, which means there is no round-trip to an external server and no re-compression stage. Images are exported at their original resolution, and audio or video is encoded to your chosen bitrate. Compare the input and output side by side — they are indistinguishable.

Almost all tools never transmit your file over the internet. Conversion, editing, and analysis happen entirely inside your browser on your own device, so the data never leaves it. The small number of features that rely on an external API (for example, AI background removal) are explicitly noted on the relevant tool page.

There are no daily quotas or per-session usage caps. File size is bounded only by the memory your browser can allocate, which in practice allows files ranging from a few megabytes up to several gigabytes depending on your device. Very large files may take longer or cause the browser tab to slow down. Splitting the file first is usually the most reliable approach.

Send an email to the address above with the tool name and a short description. For bug reports, include the browser and OS version, and the steps needed to reproduce the issue — that helps us isolate and fix it quickly. Many of the tools on the site started as user suggestions, so requests are genuinely considered.

For ad placements, API integrations, or technical collaborations, email a brief overview to the address above. We will review it and get back to you with the right contact.
