Reduce file size without quality loss.
The most common reason people compress a PDF is to send it by email. Gmail caps attachments at 25MB and Outlook at 20MB — a detailed proposal, portfolio, or scanned contract can easily exceed that limit. Compressing before you send avoids the frustration of a bounced email or having to use a separate file-sharing service just for one attachment. With HugMyPDF, you can reduce a 30MB PDF to under 10MB in seconds, entirely in your browser.
Government portals and procurement systems frequently impose strict file size limits — often 5MB or 10MB per document — for planning applications, tender submissions, and tax filings. A multi-page scanned form that comes out of your scanner at 18MB needs to be compressed before it can be uploaded. The same applies to insurance claim portals, university application systems, and HR document uploads. Having a reliable browser-based compressor means you can handle this without installing software on a managed corporate device.
Ongoing storage is another good reason to compress PDFs before saving them. Google Drive's free tier is 15GB shared across all Google services. If you regularly scan receipts, invoices, or documents to PDF, uncompressed files accumulate quickly. Compressing every scanned document by 60–70% before saving can effectively triple your storage capacity. WhatsApp also has a document size limit of 100MB but heavily compresses PDFs on its own — compressing first ensures the recipient gets the best possible quality within that limit.
