Why Compress PDF Files?
Large PDF files can be difficult to upload, email or share. Compressing a PDF can reduce its file size and make it easier to send through websites, email services and online application forms.
A smaller PDF can also require less storage space on your device. This is especially useful when uploading documents for online applications, government services, education forms and other websites with file-size limits.
