Do you know yet? Compression is suitable when you want a smaller file size, or if you need to merge multiple files into one folder. For example, if you need to email a 12MB file but are only allowed to send up to 10MB, compress the file to 7MB. The recipient will unzip the file to view the content.

Right-click the file or folder you want to compress. A menu will appear on the screen.

To select multiple files at once, you need to press and hold the Control key while clicking on each file.

You can compress almost any file, but some files (especially video and audio) can only compress a small part because they are already compressed.

Select 7z in the “Archive Format” menu. When compressing files with 7-Zip, you can choose different formats when saving the file. 7-Zip’s proprietary .7z format helps compress files to the smallest size.

The person opening the file needs to use software that can open the .7z file to decompress – it can be 7-Zip, WinZip, and the built-in Archive Utility on Mac.

If you’re worried the recipient won’t be able to open the file, you can choose zip. The ZIP format is easy to open on most devices, and still supports compressing files into small sizes.

Set “Dictionary Size” to a value at least 10 times lower than your memory. Larger compressed folder capacity means better compression, but you must have 10 times more memory than compressed folder capacity. In most cases, 128MB is enough, as it offers excellent compression at a relatively decent speed.

For example, if your computer has 8GB of RAM, you can choose a number closer to 800MB or less as the compressed folder size so that files can be compressed and decompressed faster.

Select the option to split the file into smaller files (optional). You can keep the default settings for the rest of the options. However, if it is a large file, you are welcome to split the file into smaller files. For example, you split a 12GB folder into three smaller files suitable for saving on three DVDs. Use the menu under “Split to volumes, bytes” to select the size you want to split the file into.

You need the entire split file to unzip the file. Do not delete or lose the divided files.

Picture 16 of The way to Compress large files is very easy

Select Dictionary Size (Compressed folder size). The default selection is already pre-selected based on the archive format you choose. The larger the compressed folder, the higher the file compression efficiency. However, compression (and decompression) can take a long time, and large compressed folder sizes require better computer hardware. You can try 10 times less storage, or choose the default option if your choice is taking too long.

For example, if your computer has 4GB of RAM, you can choose something close to 400MB as the compressed folder size.

“.mp3” is a popular format for music, because it supports good compression without significantly reducing the quality of the file. This format is compatible with almost any device.

“.flac” is lossless compression. This option is suitable when you want to play sound on a high-quality audio system, but it is not compatible with many devices. The .flac format also does not significantly reduce the file size.

“.ogg” produces better sound quality than MP3 with the same file size, but is not compatible with many devices.


Picture 40 of The way to Compress large files is very easy

Select sound quality. Lower quality will provide a higher compression ratio, but sound quality will suffer.

MP3: Medium and Standard options provide a decent compression ratio with average sound quality. Extreme and Insane options have lower compression ratios with higher sound quality.

OGG/M4A(ACC): Drag the slider to the left to increase the compression ratio, but reduce the audio quality. Drag the slider to the right to reduce the compression ratio and increase the audio quality.

Other file types: Use the drop-down list under “Bit Rate” or “Bit Depth” to select the audio quality/compression ratio. Lowering the bit rate/bit depth gives you a higher compression ratio, but worse audio quality.

Compress large images


Picture 42 of The way to Compress large files is very easy

Find out what you can compress. Most images that you download from the internet are already compressed. The .jpg, .gif, and .png file formats are all compressed, and continued compression will result in poor quality images. Image compression is only useful when you are processing images from digital cameras or .bmp files.

Compressed images cannot be decompressed. It is recommended that you save the compressed version as a separate file so that the original is not lost.


Picture 43 of The way to Compress large files is very easy

Learn the difference between “lossy” and “lossy” compression. Two common forms of image compression are “lossless” and “lossy”. Lossless compression is for when an exact copy is needed and is often used to compress drawings, charts, and medical images. Lossless compression is used when you don’t need to keep the sharpness of the image, and it’s common in photographic images.

The .gif, .tiff and .png formats are all lossless.

The .jpg format is usually a lossy image format.


Picture 44 of The way to Compress large files is very easy

Open the optional image editing program. Nearly every image editing program supports compression by allowing you to save the image in a different file format. When choosing a compression format, you will be given the option to choose a compression ratio.

The programs Photoshop, GIMP, and Paint allow you to save image files in a compressed format. You can compress images in most photo-editing programs, but some programs have additional options.

Photoshop is the most popular photo editing program, but if you don’t want a paid subscription, you can download and install GIMP for free. This is a program that has many features similar to Photoshop.


Picture 45 of The way to Compress large files is very easy

Open the photo in an image editing program. Each image editing program has a different way of working, but in general, the way to open the file is usually the same. Follow these steps to open an image in an image editing program:

Click File in the menu bar.

Click Open.

Select the photo and click Open.


Picture 46 of The way to Compress large files is very easy

Open the Export menu. This is the menu that allows you to save a copy of the original image in a new format. Here are the steps to open the Export menu:

Click File

Click Save As in Photoshop and Paint, or Export As in GIMP.


Picture 47 of The way to Compress large files is very easy

Select the format you want. On Paint, just click on your favorite image format. In Photoshop, you will choose your favorite image format in the selection box next to “Format”. On GIMP, click the Select File by Type menu and choose your favorite image format. The format you choose is closely related to the nature of the image.

If you are compressing a photo, choose the .jpg format.

If you want to compress images with less than 256 colors, you will choose the .gif format.

If you want to compress screenshots, drawings or comics or other types of unnatural images, you should choose the .png format.

If compressing an image with multiple layers that you want to preserve, choose the .tiff format (note, the .tiff format is not necessarily a compression format).


Picture 48 of The way to Compress large files is very easy

Click Save in Photoshop or Export in GIMP. This will save the image in the new format.


Picture 49 of The way to Compress large files is very easy

Select the quality (if possible) and click Ok . Image editing programs like Photoshop and GIMP will ask you to choose the quality and compression settings after you click the “Export/Save” button. Usually you can use the slider to adjust the compression ratio or image quality.

Increasing the compression ratio (causing quality loss) results in a smaller file size, but the image will lack sharpness and the color of the image will also be changed. You need to try the options to find the right balance between quality and capacity.
