What is NextFile?
NextFile is a browser-based file converter that allows you to convert image, audio, and video files directly on your device. Most conversions are processed locally in your browser using modern web technologies.
Is NextFile free to use?
Yes. NextFile is completely free to use. There is no registration, subscription, or hidden fees.
Do I need to install any software?
No installation is required. NextFile works entirely in your web browser. Simply upload your file, choose a format, and convert.
Are my files uploaded to a server?
For most formats, files are processed locally in your browser and are not uploaded to our servers. In some cases, temporary processing or third-party services may be used to ensure compatibility. However, we do not permanently store your files.
Are my files safe?
We do not access, view, or share your files. Files are processed automatically and deleted after the conversion process is completed. We recommend not uploading highly sensitive or confidential files unless you fully trust your browser environment.
Is there a file size limit?
Yes. There is a session-based size limit (displayed on the main page). Large files may require more processing time and device memory.
Why is my conversion taking long?
Conversion speed depends on file size, file complexity (codec, resolution, bitrate), your device performance, and browser capabilities. Video conversions may take longer than image conversions.
Why did my conversion fail?
Possible reasons include unsupported codec or format, corrupted file, insufficient device memory, or browser limitations. Try using a different format or a smaller file.
Does NextFile work on mobile devices?
Yes. NextFile is fully responsive and works on smartphones, tablets, and desktop devices.
Do you store my data?
We do not require account registration and do not collect personal files for storage. Limited non-personal analytics data may be collected (see Privacy Policy).
