That depends on the compression method used. There are some compression methods that are lossless, meaning that the original data can be 100% reconstructed. Zip files and similar methods use lossless compression.
The compression used for images, photos, and video files is typically not lossless. Depending on the degree of compression achieved, there will be artifacts (imperfections) introduced in the data. A balance must be struck between the resulting file size and the degradation of the data.
There are many pieces of software that can test the quality of a file compression software. The file compression software itself can give a percentage of compression, as well as a verification of whether it is compressed properly. One can also check the 'checksum' of the file.

The areas of compression are lossless compression and lossy compression. Lossless compression reduces the file size without sacrificing any data quality, while lossy compression reduces the file size by discarding some data, which may lead to a decrease in quality.
Adjusting the JPEG compression quality of a digital photograph can impact both the file size and image quality. Lowering the compression quality reduces the file size but may result in a loss of image detail and clarity. Conversely, increasing the compression quality can maintain better image quality but will result in a larger file size. Balancing these factors is important to achieve the desired outcome for the digital photograph.
It lowers file size and decreases quality.
The best TIFF compression method for optimizing file size while maintaining image quality is the LZW (Lempel-Ziv-Welch) compression method.
The main differences between JPG and TIF file formats are in their compression methods and quality. JPG uses lossy compression, which reduces file size but can lead to loss of image quality. TIF uses lossless compression, preserving image quality but resulting in larger file sizes. For high-quality image preservation, TIF is generally considered better due to its lossless compression and ability to retain all image details.
To reduce file size without compromising quality, you can try compressing the file using a file compression tool or software. This process reduces the amount of data in the file without significantly affecting its quality. Additionally, you can consider converting the file to a more efficient file format that supports compression, such as JPEG for images or MP3 for audio files.
The two main factors that affect the size of a picture file are resolution and image compression. Higher resolution images with more pixels will result in larger file sizes, while compressing the image can reduce the file size without compromising too much on quality.
The LZW compression algorithm reduces the file size of TIFF images by encoding repetitive patterns into shorter codes, resulting in smaller file sizes without compromising image quality.
For high-quality printing, PNG is generally considered the best file format due to its lossless compression, which preserves image quality. JPEG, on the other hand, uses lossy compression which can result in a loss of image quality.
TIFF compression is a method used to store images in the Tagged Image File Format. It is commonly used for high-quality images and supports various compression types to reduce file size without compromising image quality.
