How Do I Reduce The Size Of An Image Without Losing Quality?

Even amateur digital cameras today can record pictures in files over 10 MB. These files are good for printing, but they are not suitable for publishing on the Internet or for sending by e-mail. As a result, it becomes necessary to reduce the size of photographs by compressing them. But how can this be done so that quality does not suffer? About, how to compress a photo without losing quality, the speech will go further today.

The size of a photo is mainly determined by its resolution: the higher it is, the more the photo takes up disk space. But also sometimes the photo file contains additional datathat increase its size, but do not affect the features of the image in the picture. Removing this data from the file will help compress the photo without losing quality.

In particular, we are talking about the so-called EXIF data in JPEG files (.jpg, .jpeg). This data is additional information commenting on the JPEG image file. Typically, EXIF ​​data is immediately recorded in a picture by a digital camera and can contain, for example, information about the make and model of the camera, information about the shooting settings (shutter speed, aperture, ISO), information about flash use, type of white balance, equivalent focal length, etc. .d.

If a photo is intended simply for viewing on a PC screen, then EXIF ​​data is usually not needed, and therefore you can safely delete it. And this will not result in loss of photo quality, since such data does not affect it. How exactly can you remove EXIF ​​data from a photo? It turns out there are several ways.

Use built-in Windows tools

Using Windows Explorer, you can easily delete EXIF ​​data from image files stored on local PC drives. To do this, you must first select the photo file, open the context menu with the right mouse button and select the “Properties” item. In the window that opens, then you need to go to the “Details” tab and click on the link “Removal of properties and personal information”.

In the window that opens, it remains to choose exactly how the data will be deleted: you can delete all existing information by creating a copy of the file, or you can manually delete only individual properties at your discretion. After that, it remains to click only the “OK” button to confirm and close the properties window.

Use graphic editors and image managers

Various editors and image managers usually have functionality to remove EXIF ​​data from files. For example, in the popular free manager FastStone Image Viewer, the tool for deleting such data is called “Delete JPEG metadata”, and in the well-known free GIMP editor, you can remove EXIF ​​data from the file using the Save for Web plugin.

As you can easily guess from the name, the plugin Save for Web is intended for saving images in GIMP, optimized for placement on the Web. To delete EXIF ​​data using this plugin, just select the Save for Web item in the “File” menu of the editor and when saving a photo in JPEG format, check the “Strip EXIF” item in the quality settings. The image will be saved without EXIF ​​data.

By the way, when using this plug-in, the size of the final file for saving is estimated on the fly, and therefore you can immediately estimate how much the EXIF ​​removal will reduce the photo.

Use special utilities

If you have to delete EXIF ​​data more or less regularly, then it may make sense to use separate utilities for this. Most of these utilities are available free of charge and have a very simple interface. Examples include Free EXIF Editor, QuickFix etc.

Thus, removing EXIF ​​data allows you to reduce the size of the photo file and not lose image quality. But sometimes the decrease is not as significant as we would like. In this case, it is convenient to resort to the help of various online photo compression services without loss of quality.

There are many similar services today. For example, one of them is Optimizilla (optimizilla.com). Using Optimizilla is extremely simple: you need to download the file to be reduced and either agree with the automatically selected compression level, or adjust it manually using a convenient “slider”. The service immediately shows what the size of the final file will be and how much smaller it will be (in percentage). You just have to download the optimized image to your computer.

By the way, the Optimizilla service is convenient because it can be used to process several images at once – up to 20 images. Supported formats are JPEG and PNG.
