Làm thế nào tôi có thể chắc chắn nhận được email bạn gửi cho tôi?

To prevent spam emails in the users inbox, email providers have developed different algorithms to classify an email as spam or ham. Normally, emails from are not classified as spam, because we never send unwanted emails. But some email providers have algorithms that seem to need some more fine tuning.

To be sure that emails from us get straight to your inbox, you need to whitelist "" before we send an email to you. To do so, go to your email account and add us to your contacts, contact list, whitelist, create a filter or whatever it is called by your email provider. Of course you can always revert this whenever you decide.

Privacy & Safety

Do you keep a copy of my file?

We do not keep a copy of your file.

You can delete your file from our server immediately after the conversion. Otherwise, all transferred files will be automatically deleted after 24 hours or after 10 downloads.

We guarantee the privacy of your file because no one else has access to the file except you. Online-Convert does not back up or actively monitor your files; the service is completely automated.

Are my files safe? Is Online-Convert safe to use?

We understand the concerns about your privacy. These are the steps we take to protect your files:

  • Tất cả các file bạn tải lên sẽ tự động bị xóa sau 24 tiếng hoặc sau 10 lần tải xuống, tùy theo điều kiện nào đến trước.
  • In addition to that, you also have the option to delete the file instantly from our server after you have downloaded it.
  • Không có bản sao lưu từ các tập tin của người dùng.
  • The contents of the files are not monitored without the permission of the uploader. A manual review of all files would not be possible anyway due to the high amount of files we process each day.
  • The download of your file can only be triggered via the unique, non guessable download URL you got from us.
  • You keep the copyright and ownership of the source file and the converted file at all times.
Bạn có quyền hợp pháp đối với file của tôi khi tôi sử dụng dịch vụ của bạn không?

Absolutely not. We do not intend to gain the legal right to your files. In addition, all user files are deleted after a short period of time.

In other words, you keep the copyright and ownership of the source file and the converted file. We don't own or have exclusive rights to your content.

I have found a security issue. How do I report it?

We recognize how important it is to help protect your privacy and security. If you believe you have found a security issue, we will gladly work with you to resolve it.

Please, contact us via email and report the problem. When properly notified, we will do our best to process your emailed report, investigate the issue, and fix potential problems as quickly as possible.

Can anyone else see the files I convert?

We do not read, look into, or make any copies of your files. All file processing is completely automated. Therefore, there is no human interaction with the files.

You can delete your file from our server immediately after the conversion is done. Otherwise, all transferred files will be automatically deleted after 24 hours or after 10 downloads, whichever comes first.

What is your privacy policy?

We put great importance on the protection of your data and the protection of your privacy.

If you want to know how Online-Convert handles your data, how our services work and how the protection of your personal data is guaranteed, please check our Privacy Policy you can access at this link.


Tôi không thể chuyển đổi tập tin. Chuyện gì đã xảy ra?

There can be a lot of reasons why the conversion has failed. For example:

  • The source file is corrupted
    • This happens, for example, when important metadata does not exist at the end of a file. If, for a reason, the saving of the file during recording is stopped (e.g. due to power outage, device full), this metadata is not written.Unfortunately, without this metadata, the file is basically useless.
  • The source file has been encrypted with Digital Rights Management (DRM) by the owner.
  • Some codecs inside a file format container that are normally working can't be converted.
  • Trình chuyển đổi không nhận ra định dạng nguồn.
  • If you have entered an URL (like https://www.example.tld/test.php) to submit the file you want to convert, be sure to provide the direct link to the image/music/document file, not to the website itself. Right-click on the link to the file on the website, try to copy the direct URL, and paste it into one of our converters.
  • The download link you provided is not accessible by the converter. Possible reasons could be that the file is not available for direct download due to copyright issues or you need to log in to access it. In these cases, you can try to download the source file directly to your computer and upload it from there to our converter.

If you feel like there is an error, don't hesitate to contact us via email. We are constantly trying to improve our converter and we would appreciate your feedback.

I'm experiencing problems during the upload of the file.

If your upload fails, it's probably due to one of the following reasons:

  • The file size limit to upload a file and convert it for free is set to 100 Megabytes. In order to be able to upload bigger files, please take a look at our premium services.
  • The connection between your computer and our servers is temporarily unstable. Please try again later or from a different network or computer.
  • The upload of large files is blocked by a proxy of your organization/provider.
  • Sometimes, only the upload progress bar gets stuck, but the file has been fully uploaded and converted. You can check this when you register for free and look at the conversion history on your user dashboard.
  • Uploading files is quite a bit slower than downloading files because most high-speed internet connections are designed to provide much better speed for downloading than uploading.
I can not find the downloaded file.

If you have processed a file and clicked the "Download" button on a tool page, your file should be in the default download folder. In cases where you receive an error message, or your browser stops working, please try to download your file again.

How long will the converted file be available for download?

Đường dẫn liên kết chúng tôi cung cấp cho bạn để tải xuống file đã chuyển đổi có hiệu lực trong 24 giờ hoặc 10 lần tải xuống, tùy theo điều kiện nào đến trước.

Why does my conversion take so long?

Processing speed depends on many factors. The time it will take to get your files converted will depend on your own internet connection speed, the size of the uploaded files, and also on how busy our servers are.

Are there files that can not be converted?

There are a couple of reasons why you might not be able to convert your files.

  • The most common ones being:
  • the original document is corrupted
  • password or any other protection is enabled for the original document.

Please, check the original file on your computer and make sure that it is opening properly. Also, check that the file does not require a password to open and does not have any protection enabled.
