Frequently asked questions
What is OneFileConverter?
One website for all your file jobs: convert, compress, merge, split and edit PDFs, documents, images, video and audio, without switching between apps.
Is OneFileConverter free?
Yes. Every tool is free to use, with no sign-up and no watermarks on your files.
Are my files safe?
Yes. Your files are only used to create your result — never shared, and never used to train AI. Web page to PDF upload your file to our server; those tools say so before you start, and files are deleted right after conversion.

No. It works in any modern web browser on desktop or mobile. Recent versions of Chrome, Edge, Firefox and Safari are supported.
Which file types are supported?
PDF; images such as JPG, PNG, WebP, AVIF and iPhone HEIC photos; MP4, MOV and WebM video; and MP3, M4A, WAV, OGG and FLAC audio.

Each tool shows its limit next to the upload area.
