Questions about converting files online
What is an online file converter?
It is a web page that changes a file from one format into another, for example a PDF into a Word document or a PNG into a JPG. BestConverter does this inside your browser, so you get the result without installing software or uploading the file.
What can I convert with BestConverter?
PDFs to and from Word, Excel, PowerPoint, RTF, EPUB, text and images; images between JPG, PNG and WEBP; and video and audio files. There are also tools to merge, split, compress, sign and edit PDFs.
Does it cost anything?
No. All tools are free, with no trial, no sign-up and no watermark on the files you download.
Where are my files processed?
On your own computer or phone. The page loads the conversion code into your browser and your file is read there, so it is never sent to a server.
