Many things that previously could be done only by means of specific programs installed on your computer, now you can do just visiting the sites.
These online services I use quite regularly.
1. Saving videos from Youtube and other online video. http://sfrom.net. Adding to the address "sfrom.net/": it was https://www.youtube.com/watch? v = sVxbmXJOUL8 - becomes: sfrom.net/ https://www.youtube.com/watch? v = sVxbmXJOUL8. Then click "download without install".
For Youtube, you can simply add the two letters "s" to the address:
https://www.youtube.com/watch? v = sVxbmXJOUL8 -> ssyoutube.com/watch? v = sVxbmXJOUL8
2. Converter video to animated GIF https://ezgif.com/video-to-gif. You can select the start and end time, change the size and number of frames per second, adjust the brightness, contrast, and more many, many things.
3. Converter all video to MP4 https://ezgif.com/video-to-mp4. On the same site there is an excellent video converter any (understands MTS, FLV, MOV, 3GP, and a bunch of other formats).
On the same site there is a lot of video processing functions - cropping, resizing, reverse, turn.
4. Getting the title image from the video Youtube http://shpargalkablog.ru/2013/06/youtube.html.
5. Text to HTML Converter http://ru.texthandler.com/text-tools/text-to-html/. Converter is valuable because it does not touch the html-tags in the text and allows you to convert "under-HTML" Learn to normal html, adding tags paragraphs and line breaks.
6. Converter excel spreadsheet to html http://www.avalanche.kiev.ua/site/free/convert-table-html.html.
Finally, two simple website, without which of course you can do by using an ordinary calculator, but they allow you to save a little time.
7. Calculation of the volume of air passing through the air duct https://calc4u.ru/index.php/aerodinamika/ob-em-vozduha.html. A useful calculator for anyone interested in ventilation.
8. Calculation of the cross section of the cable diameter https://systemssec.ru/info/calc/raschet-secheniya-kabelya-po-diametru/. Text around the calculator do not read - there are plenty of grammatical errors and follies.
Surely there are still many useful online services, converters and calculators. What do you use?
