It is interesting to know that there are free tools on the Internet that we often think there is only a paid version of them. We sometimes find services on the Internet that do the work of complex paid software.

The Internet is a wonderful place. It allows you to answer questions that you previously could only ask technical experts or do a lot of searching in libraries.

The Internet has connected all human beings closely and has long been an indicator of well-being and, beyond that, a fundamental human right.

In this post, I will share some of the most interesting ones with you:

1- Photopea

It is a Photoshop clone, and, interestingly, it is entirely free. The sidebar only displays a series of non-annoying ads.

2- Gothenburg project

Many are familiar with the Gutenberg project, and many are not yet. You can find many classic books on this site if you are a seeker. I once used it to see the original versions of books, compare them with translations, and learn tutorials.

3- Khan Academy

The Khan Academy website offers plenty of courses infields youu can not even imagine

With the help of Khan Academy, you can participate in a prestigious university course and gain knowledge and experience in fields separate from your routine educational background.

4- Skiplagged

Of course, this tool does not help us. However, it has an exciting function: it prevents airlines from financially abusing customers. Skiplagged calculates which airlines are cheaper to travel from city A to B and even shows you how much you can save if you travel through an intermediary city and switch flights in that city.

The site performed so well that United Airlines complained.

5- Scihub

You can find a lot of academic books and textbooks on this site.

6- My 90s TV

This one is exciting. This site is a nostalgia TV and shows you old TV shows, music videos, movies, and trailers from the ’70s, ’80s, and ’90s on the skin of an old TV.

7- Archive site

Many of you are familiar with this one. An archive site is an accurate archive of web and culture archives. In it, you can find everything valuable, from DOS games to old books and magazines and even old copies of sites, some of which no longer exist externally.

8- Gimp

How do you know Gimp ?! A free photo editor with features comparable to the basic features of Photoshop.

9- Freecycle

It is an interesting Internet service to get rid of tools and goods that are no longer useful to you and do not intend to wait long for a buyer to find them.

10- Unsplash site

Sometimes, finding high-quality photos in a non copyrighted field isn’t easy. With Unsplash, you can browse and use the world of free images that photographers themselves have given free access to.

11- 1aauto, be your car repairman

In the first step, you may think this site is just for selling and supplying car parts. But its videos can help you get acquainted with car parts, learn how to replace them, and repair your car.

12- Camelcamelcamel site

A site that compares the price of a product on different sales sites so you can find the cheapest place. In Iran, of course, we have sites with similar functions. But what a benefit is that most prices are so high, and the price difference is insignificant!

13. Duolingo language training site

A site for teaching different languages.

14. Future site

Want an email sent to you years later? Imagine for a second you were transposed into Earl’s karmic-driven world. Write down your goals and aspirations for the next decade or two.

Of course, if this site and you have survived by then!

15- Zotero

Free tools for researching and combining different information sources and easily referring to the sources used, both in footnotes and in the text.

16- Library Genesis

Another source for finding textbooks and academic books

17- Terms Of Service; Didn’t Read

We often do not read the services’ terms of use, so we quickly press the OK or next‌ button and move on.

This site is for the lazy and bored. It explains these conditions in a suitable format and clear and straightforward language.

18. Openlearn site

British site, containing various training courses and even valuable documentaries.

19. Heavens-Above site

If you want to know which bright spots in the night sky of the International Space Station, the Hubble Space Telescope, or the Starlinic satellites are visible to you, use this site, which also has an Android app.

20- Flightradar24

A site to show you live air traffic. For example, if you want to know what flights are currently flying over Iran, you can use this site.

21- Melody Ml site

This is an exciting service. You can send music in mp3 format to this site so that later versions, for example, without the singer’s voice and only the background music, will be emailed to you.

22- Blender

Free 3D tool and open-source video editor

23- Thenounproject

Free icon and photo finder

24- The Anki Flashcard
