Converting pictures and photos

2014-03-15 10_07_17-Start Menu Good afternoon.

Today, hundreds of thousands of different pictures and photographs can be found on the Internet. They are all distributed in various formats. If you work with them, sometimes you need to change their format: to reduce the size, for example.

Therefore, in today's article we will touch upon not only converting images, but also dwell on popular formats, when and which one is better to use …

1. Best Free Converter and Viewer

xnview-512 XnView (link)

Free image viewer. Supports about 500 different formats (at least judging by the description of the developers)!

Personally, I have not yet met graphic formats that this program could not open.

On top of that, there are a bunch of options in her arsenal that will be very useful:

– converting pictures, including batch conversion;

– creation of pdf files (see here);

– search for identical pictures (you can save a lot of space). By the way, there was already an article about finding duplicate files;

– create screenshots, etc.

Recommended for unambiguous acquaintance to everyone who often works with images.

Today, there are dozens of graphic file formats. Here I would like to note the most basic ones, those that make up the majority of the pictures presented on the net.

BMP is one of the most popular formats for storing and processing images. Pictures in this format take up a lot of hard disk space, for comparison, 10 times more than in JPG format. But they can be compressed by an archiver and significantly reduced their size, for example, for transferring files over the Internet.

This format is suitable for images that you plan to edit later, because it does not compress the picture and its quality does not decrease.

JPG is the most used format for pictures! In this format, you can find hundreds of thousands of images on the Internet: from the smallest to several megabytes. The main advantage of the format: perfectly compresses the picture with decent quality.

It is recommended to use it for pictures that you will not edit in the future.

GIF, PNG are common formats on various websites on the Internet. Thanks to them, you can compress the picture dozens of times, moreover, its quality will also be at a decent level.

Plus, unlike JPG, this format allows you to leave a transparent background! Personally, I use these formats precisely for this merit.

3. Converting one picture

In this case, everything is quite simple. Let's take a look at the steps.

1) Run the XnView program and open any picture that you want to save in a different format.

2) Next, click on the 'save as' button.

By the way, pay attention to the bottom line: the image format is displayed, its checksum, how much space it takes.

3) The program will offer you 2-3 dozen different formats: BMP, JPG, TIF, ICO, PDF, etc. In my example, I will choose BMP. After choosing the format, press the 'save' button.

4) Everything! By the way, at the bottom of the image you can see that saving the picture in BMP format – it began to take up much more space: from 45 KB (in the original JPG) it became 1.1 MB (which is ~ 1100KB). The file size has increased by about 20 times!

Therefore, if you want to compress images well so that they take up less space, choose the JPG format!

4. Batch conversion (several images at once)

1) Open XnView, select our pictures and press 'tools / batch processing' (or the combination of Cnrl + U buttons).

2) A window with settings for batch processing of files should appear. You need to ask:

– folder – the place where the files will be saved;

– format for saving new files;

– go to the transformation settings (the tab next to the main ones, see the screenshot below) and set the image processing options.

3) There are a hundred truly impressive options in the 'transform' tab, allowing you to do everything you can imagine with pictures!

Some of the list offered by XnView:

– the ability to make the picture gray, black and white, desaturate certain colors;

– cut out a certain part of all pictures;

– set a watermark on all pictures (handy if you are going to upload pictures to the network);

– rotate pictures in different directions: flip vertically, horizontally, rotate 90 degrees, etc .;

– resize images, etc.
