What is a PDF Compressor?
A PDF Compressor is a utility that reduces the file size of your PDF documents. Large PDF files can be difficult to email, upload to portals, or share with colleagues. By compressing the document, you make it much easier to distribute while maintaining the readability and quality of the text and embedded images.
Why Compress PDF Files?
There are several compelling reasons to optimize your PDF documents:
- Email Attachment Limits: Most email providers restrict attachments to 20MB or 25MB. Compressing your PDF ensures it easily passes through these limits.
- Faster Uploads & Downloads: Smaller files transfer significantly faster over the internet, saving you and your recipients valuable time, especially on mobile networks.
- Save Storage Space: Archiving hundreds of unoptimized PDFs can quickly consume your hard drive or cloud storage space. Compression helps you store more files efficiently.
- Website Performance: If you host PDFs on your website, smaller files mean faster load times for your visitors and less bandwidth usage for your server.
