Nowadays, we live surrounded by files that take up more and more space on our devices.
Whether it's photos, videos, work documents or creative projects, they all seem to grow in size without us noticing.
And, of course, there comes that awkward moment when your computer or cell phone warns you that the memory is about to fill up.
This raises the big question: is it possible to compress files without loss of quality?
The answer is yes, and in this article we are going to see how to do it step by stepno funny tricks or complicated solutions.
What does it mean to compress files without loss of quality? 🔍
When we talk about compressdoes not always mean the same thing.
There are two main types of compression:
- Lossy compression ➝ greatly reduces file size, but sacrifices image, audio or video detail.
- Lossless compression ➝ the size goes down, but the content remains exactly the same.
For example, a ZIP file containing text documents will remain intact when you unzip it.
The same goes for formats such as PNG in images o FLAC in audiodesigned to maintain the original quality.
