이미지 파일 용량 줄이기 방법Sometimes a photo or image is too large and needs to be reduced. Today, I’m going to learn how to reduce the size of a photo. We will cover in detail from sites that reduce the size of photos without compromising image quality, how to lower the resolution with a program, and how to reduce the size on a mobile phone.

There are sites that allow you to compress pictures (images) without losing quality. There are many sites, but I will introduce only three that I use representatively among them.
Tingypng is the most representative photo (image) compression site (address: tinypng.com). You can compress image files such as Jpeg, png, and webp without deteriorating the quality. Up to 20 files of 5MB or less can be compressed at once (no limit)
It is very convenient because all you have to do is drag the image file stored on your PC to the center of the homepage, and although it depends on the file, the compression rate is usually 40-60%.
Compressed picture (image) files can be downloaded individually or collectively. The image quality does not deteriorate to the extent that you cannot feel the difference between before and after by looking at it with your eyes.
iloveimg is a site that allows you to edit photos (images) from web pages. In addition to image compression, it has several functions such as resizing, inserting watermarks, and cropping images (Address: https://www.iloveimg.com/en).
Unlike tinypng, iloveimg can reduce gif files and compress files over 5MB. By subscribing to the site, you can compress up to 30 images at a time.
Because it has many advantages, such as being able to edit photos directly online, iloveimg is also used by many people. The way to reduce the size of a photo is almost the same as tinypng.
Squoosh is a site where you can manually adjust the compression ratio (address: https://squoosh.app). Users are given the choice to increase the compression rate even if they give up a little bit of quality. Photo (image) compression method is similar to tinypng and iloveimg (drag).
Squoosh has the advantage of being able to check before/after by scrolling before compression, and being able to fine-tune the compression rate.
There is a limit to reducing the size of a photo with the above method. In order to dramatically reduce the size of a picture, the resolution must eventually be reduced. Let’s see how to lower the resolution with a simple program that can be used on a computer.
Photoscape is called entry-level Photoshop. Although it is a free program, it provides all the necessary functions for photo editing.
It depends on the version, but usually you can find ‘Resize’ in the ‘Edit Photo’ menu and correct the pixels. If Maintain Aspect Ratio is checked, modifying the horizontal value automatically corrects the vertical value as well.
Please note that even if the horizontal pixel size is reduced to only 700-800px (based on horizontal photos), it is generally not difficult to view on mobile. Unless it’s a photo of the work.
By the way, you can download Photoshop for free here.
If you don’t want to download a program, you can also use Paint, which is installed by default in Windows. After importing the photo file, click ‘Resize’ to reduce the resolution. The default is set as a percentage, but you can directly enter how many percentages to reduce.
In addition, there are several photo editors such as Windows 10 Photo Viewer and RC. You can easily reduce the size by looking for a place to adjust the size in the menu.
So far, we’ve looked at how to reduce the size of photos on PC, but there may be times when you want to reduce the size on your smartphone. The simplest way is to send a photo file to yourself in the KakaoTalk chat window.
You can set the image quality in the KakaoTalk ‘Settings > Chatting > Picture Quality’ menu, and you can greatly reduce the size of the picture by sending only the ‘normal quality’ that is set by default.
If you want to adjust the resolution more precisely, there is a way to edit it in the phone photo (gallery) editor. In the case of a Galaxy phone, select ‘Select photo → Edit → More (top right corner) → Resize’ in this order.
For reference, you can also reduce the size of a photo without deteriorating the quality on your phone. First of all, access a site like tinypng, which I introduced earlier, from a cell phone mobile web browser. In this case, you should select the photo file directly, not the dragging method.
You can also use a dedicated image compression app like Photo Compressor to make it a bit easier.
So far, we have summarized how to reduce the size of a photo. If you know of a good method, please share it in the comments.
