How to convert PNG to JPG? How to convert TIFF to JPEG? Or even how to convert to GIF? What Mac image converter to use? These and such like questions often arise among the modern users. The reason is very simple because nowadays, there is a great variety of formats, including JPG, GIF, PNG, TIFF, BMP and we all know that each format has its own pluses and minuses and can have a great variety of usage. Namely, the way you want to use one or another image will affect the choice of conversion, whether to convert GIF to JPG, JPG to PNG or to convert PNG to JPEG, or maybe there is a necessity to convert TIFF to JPG. If you think that only professional photographers puzzle head over this issue, do not want to disappoint you but it is not true, because an ordinary user may face the necessity to convert images as well.

Wondering how it could be? Let’s imagine, you have an account on some forum or you have registered on some site and what to upload an image, you click on the upload option, wait for a couple of seconds and obtain the result something like “Sorry, but the type of the image you want to upload is not supported” or “Unacceptable file format”. The thing is that a great number of websites as well as applications, unfortunately, do not accept images if they do not end up with .JPG extension. Now everything seems to be clear, and you know the reason for such error messages as you wanted to upload a PNG file. However, with the help of PNG to JPG converter, this problem could be solved within a couple of minutes.

Also, it is worth mentioning that, when choosing the format of the image, you need to take into consideration these 3 factors, namely:

  • Whether to compress the photo and sacrifice its quality of the photo in order to get the fast and efficient loading and sending.
  • Whether to minimize the size of the image, if you are limited to the space for storing your photos.
  • Whether to increase transmission speed if you are planning to send images frequently.

Besides these factors, there are of course a lot of other reasons. However, all these reasons lead to other questions like "How to convert" as well as "Which image converter for Mac solution to use?" as there is a plenty of software offering such feature. Some of them can convert BMP to JPG only while others provide you with a support for a lot of formats. So if you have images with .GIF, .TIFF, .PNG or any other file extension do not worry, with a decent image converter you will not need to rack your head anymore.

By the way, according to the statistics, the most commonly used image extension nowadays is JPG or JPEG as it is also known. And in most cases, you would find yourself most likely to convert different image formats into this kind of image extension, even though other formats of an image can also have a great sphere of application. Nevertheless, converting photos manually or even doing so for a single file, can take time, especially if you work with hundreds of photos every day.
