Frequently Asked Questions


Who will see your files? What is file availability?

On, you can set up 3 different levels of availability for your files:
- Public: The public file is for everyone. Anyone can find it in search or via a link.
- Via link: You will not find the file shared by the link in Search.
But everyone who has a link for sharing will get to it. You will find the link on File Detail.
- For me only: Indicates your private file. You will only see it when you sign in to your account and no one else will get to it.

How could you set who will see your file? Where could I change the availability?

You can already set the file availability when you upload, or it means who will see the file. You can change the properties of your file, including availability, at any time in File Detail or through My Files. Beware, you can only change the properties of your own files!

Are the photos of your family and especially of your children safe on

Files as such certainly, but you probably do not want to show to everyone the pictures of your children in the bath or at the sea.
In the case of uploading especially the naked children to the internet, do not forget to always protect them from seeing them by other people by choosing the files and folders with children as private or password-protected. Password setting is recommended whenever your children are partially or completely exposed!

Is it reasonable to upload the personal photos and videos as an anonymous user?

This option exists here, but we do not recommend it for this kind of files!
You can not mark anonymous files as private, and you have no control over them in the case of administrative misconduct and moving the file to another service. For personal photos and videos, we always recommend working with them only as a logged-on user who has all of these options available.

Why do you need to know if I'm over 18?

This information identifies the content. For example, minors are not shown an advertisement for alcohol or tobacco, etc.


How does online video streaming work? Can I download this file too?

Some files on are available for online playback. But that does not change the download possibilities.
You can play short videos for free, for playing longer videos you have to sign up and use your credit. When you start playing, you are charged with the same amount of credit as when you download the file. The file for which your credit was deducted, you can download or play the next 24 hours as you wish.

Why streaming doesn’t work for all videos?

Not all file formats are suitable for online streaming. Video files have to meet our internal parameters like quality, size and length. Videos shorter than 10 minutes are always available for online streaming (if the file is not corrupted).

Can I add or change subtitles while streaming a video?

Yes, you’re able to change or add your own (external) subtitles using the blue video player.

Video has multiple audio tracks, can I change them while streaming?

Only one audio track is available while streaming. For changing the audio track, you have to download the file and play it in your favourite video player on your mobile, tablet or computer (we recommend VLC). If you already started to stream the video and spend any credits on it, don’t worry. You can always download or/and stream any file at full speed free of charge/credits throughout 24 hours from spending the credits for it.

I can not play free preview of streaming videos. How can I solve it?

You can try to play preview in different browser (like Chrome, Firefox, or Safari). A persistent problem may indicate an error in the system time of your operating system. So try to synchronize it to the correct one (for example

If your file has been moved to and you disagree with it, you can ask as a file owner to move it back at File detail by selecting 18+ in the properties.

In the case not even one option is available for you, please, contact our technical support with the link to the file ( you want to delete.

I sent an SMS with the text ULOZTO (for quick registration) and I've received a password. What should I do with it?

By sending an SMS with the text ULOZTO you've made a so-called Quick registration. We created an account with the same user name as your phone number (for example 420724123123) and with the password you just received in that SMS. These credentials are not for registration, you can use them directly to sign in.

I made a mistake in the SMS. Is there any solution?

- If there is a mistake in the recipient's number, the SMS will not reach our payment gateway provider, and therefore even us. So you need to contact your mobile operator.

- If there is a mistake in the text (for example, ULOZTO is missing or misspelled), the SMS will reach the payment gateway provider, but not us. Please contact us and we will try to declare the SMS. In the application, please include the phone number from which you sent the SMS and your login name.

- If there is a mistake in the text (but keyword such as ULOZTO is correct), it is likely that you have recharged your account to someone else, please contact our technical support. Please include the phone number from which you sent the SMS and your login name.

- If you can not send SMS, you need to contact your mobile carrier.

The reasons may be:

  • You do not have enough credit
  • You owe your carrier
  • You have exceeded the limit
  • You do not have Premium SMS enabled
  • You are abroad / you have active roaming

Can I recharge my credit via SMS one-time? Will the SMS not be charged automatically in regular term?

The SMS for charging credit isone-time. Sending recharge SMS does not bind you to regular payments in any way. You can recharge the next credit when you need it. The current SMS text and their prices can be found on the Price list.

What a Dark mode and how could I turn it on/off?

As its name implies, dark mode darkens the user interface. In general, the appearance is inverted so that instead of black text on a white background, you see light or white text on a black background. Dark mode helps protects your eyes from the traditionally blinding whiteness of computer and phone screens. You could always turn it on or off - on computer head to top right area of our page where you can find toggle - moon and sun (pretty self-explanatory, right?). On mobile devices, this option could be found inside the top-right menu.

Smart TV

How to start on Smart TV?

First, please make sure, that your Smart TV is connected to the Internet. Find the Web browser icon in the applications (for Samsung Smart TV, you can access the applications by pressing the Smart hub button on the remote control - cube-shaped button). In the browser, activate the address bar, enter the internet address and confirm. You can not download files on Smart TV. However, you can view pictures and play videos. You must be logged with a credit to play longer videos.

Can't use it at all, ads are randomly displayed instead of video!

We recommend you to activate the special TV mode, which should greatly improve usability on smart TVs.

How can I use service on Smart TV?

Web browser on Smart TV allows two modes of movement on the web, the cursor mode Pointer and Tab mode, in which you are moving by using tabulator character. However, Tab mode options are very limited. Therefore, we recommend using Pointer (cursor) mode. Mode switching is available in web browser Settings.

I can’t play some/all of the content from Ulož.to on my TV

Your TV doesn’t have to support this specific video type or streaming at all. Sadly, there’s not much we could do about it as TV browsers are like IE - not really browsers. Try to update your TV and find more information inside TV manual. on my Smart TV is not displayed on a full screen or the image is distorted. How can I solve it?

If you do not see the correct picture format while watching the contents on the on Smart TV, you can change it. Press the Format button on the TV remote control and select Picture format. And select Fit to screen. Depending on the TV manufacturer, the label may slightly differ.

Ulož.to is not working properly on my Samsung Smart TV, what shall I do?

Unfortunately, web browsers on Tizen OS 3.0 or older are way too old to work properly, as they utilise web browser from 2015. On Tizen OS is, for good user experience with Ulož.to, required at least browser from the end of year 2016, which means Tizen OS version 4.0 or later. Tizen OS does not allow installation of alternative web browser. Always try to update your Smart TV to the latest firmware version.
If it will not help (very probably not, as Samsung's update policy is very passive), you can - besides of buying newer Smart TV, try following:

  1. Buy external streaming device, such as Roku, Fire TV, Google Chromecast, Apple TV etc.
  2. Connect your PC (via HDMI, for example) or game console (Xbox, PlayStation) and send data to your TV through it.
  3. Buy some cheap miniPC and connect it to your TV solely for this purpose.
  4. Try so called Screen Mirroring from your desktop, laptop or smartphone (via Bluetooth or WiFi).

Older Smart TVs (it is important which version of OS Tizen is the device running, not when it was manufactured or bought) will not work with Ulož.to in 2020 and on correctly.
