Sometimes you need to change an image, audio file, or video quickly, so you search for an online tool. Problem: Many online conversion tools are not safe to use, put you at risk from malware or mining your data.
Green color It’s not like that. It is an open source, a browser-based tool that can change the most common image, audio, video and document formats. It is not full of advertisements and you do not need to create an account to use it. More important thing: the device works perfectly in your browser (almost), which means your files are not really uploaded (save for video files, as I will explain below). I tested it by opening the website, closing my WiFi and converting a large batch of images and documents. it worked.
Changing files without uploading them is great from a privacy perspective, but also sharp – you are not waiting for files that you are waiting for files to move back and forth over the server from your machine.
To start with Wart, go to the website and add the files that you need to pull from your file manager or to secretly using the upload button. (The homepage lists all supported file types, if you are eager – there are more than five dozen of them.)

You can alternately convert all your files into the same format and catch them all in the same zip file. Note that it will only work when all the files dropped in the tool are of the same type – that is, video, image, document or audio files. For example, a mixture of images and videos cannot be converted to once, as there is no format that you can convert them.
What do you think so far?
It is also worth noting that video files cannot be converted without uploading on a server, mostly due to how the resource to do so in the browser will be intense. The device will warns you before uploading anything. According to the website, after downloading your file or by you uploading them, whatever comes first, the video is removed from the server. It is possible to set your own server, if it really worries you.
I think it is very easy to use a vert tool. I tested it with an EPUB file and was able to create a word document and a website. I also tested it with various images, audio files and videos – it all works well, and quickly. There are some caves. PDF files are not supported to import or export. And some of my old Word documents had an error message, which was strange, but was not completely unexpected (the files in question were more than 20 years old). Overall, however, it is a very easy tool – a well -booking is worth bookmarking.
