Why compress PDFs to 20kb

Having a PDF that's too large can get in the way of a surprising number of everyday tasks. Sending a scanned invoice by email, uploading a signed contract through an online portal, or sharing a report with colleagues can all run into trouble if the file size exceeds what the platform allows. Many services cap attachments at a few megabytes, and even when there's no hard limit, bloated files are slower to send and receive. Compressing your PDF down to 20KB keeps things moving smoothly, whether you're dealing with a single-page document or a short multi-page file.

Zamzar's online PDF compressor does the heavy lifting for you. Simply upload your PDF, let Zamzar compress it, and download the smaller version in a few moments. A 20KB target works well for text-heavy documents like letters, invoices, or application forms, where you don't need to preserve high-resolution images. This is especially useful if you've scanned a paper document, as scanned PDFs tend to be far larger than necessary. A student submitting a scanned essay, or a freelancer attaching a proposal to an email, will find that a compressed PDF slots neatly into most upload and attachment limits without any fuss.
