Frequently asked questions
Which conversions work today?
2,805 conversions (archive, audio, document, ebook, font, image, pdf, presentation, spreadsheet, vector and video) work on this server right now. The rest of the 3,512 conversions in the menus are on the roadmap and are clearly marked “coming soon” until they work.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
