There are several reasons why you may want to compress PDF files:
- Smaller file size: PDF files can be large, especially if they contain a lot of images or graphics. Compressing the file can reduce its size, making it easier to store, send, and share.
- Faster uploading and downloading: Large PDF files can take a long time to upload or download, especially if you have a slow internet connection. Compressing the file can speed up the process, making it more efficient.
- Save storage space: If you have limited storage space on your device or cloud storage, compressing PDF files can help you save space and keep your files organized.
- Improved performance: Large PDF files can slow down your device or software, making it harder to work with the file. Compressing the file can improve performance and make it easier to navigate and work with.
Compressing PDF files can help you save time, space, and resources, making it an important step when working with large or complex PDF files.
