Question 1

Is this file converter free?

Accepted Answer

Yes. Every conversion on ConvertFlow is free, with no sign-up and no watermarks. We're funded by voluntary support from people who find the tools useful.

Question 2

Are my uploaded files secure?

Accepted Answer

Files are uploaded over HTTPS straight to private storage. They're never publicly accessible, they're processed in isolated workers with no internet access, and download links expire after a few minutes.

Question 3

How long are files stored?

Accepted Answer

Uploaded and converted files are deleted automatically after 60 minutes. Abandoned uploads are deleted too.

Question 4

Can I convert multiple files?

Accepted Answer

Tools that work with several files (such as merging PDFs or compressing images) let you add multiple files at once. Single-file tools process one file per conversion.

Question 5

What is the maximum file size?

Accepted Answer

You can upload files up to 25 MB each. Some tools also limit image dimensions or page counts to keep processing fast and reliable.

Question 6

Do I need to create an account?

Accepted Answer

No. All tools work without an account.

Question 7

How can I support ConvertFlow?

Accepted Answer

If ConvertFlow saved you time, you can make a voluntary support payment on our Support page. It helps pay for servers and storage and keeps the tools free for everyone.
