Compress PDF files that are too large to send
Large PDF files turn small tasks into delays. Email may reject the attachment, upload forms may complain about size, and sharing from a phone becomes annoying. Compress PDF gives you a lighter copy of the same document from inside the browser.
The tool rewrites the PDF with object streams and removes avoidable overhead where it can. Results depend on the original file. A text PDF and a scanned image PDF will not shrink the same way, but this is a quick first step before you send or upload the file.
Use it for resumes, proposals, invoices, scanned forms, reports, or any PDF that needs to be easier to handle without opening a desktop PDF app.

FAQs
How much smaller will my PDF become?
Compression depends on the original PDF. Text PDFs may reduce well, while scanned image PDFs may need image-level compression for larger savings.
Will my PDF content change?
The tool keeps the same pages and content while rebuilding the PDF in a lighter format where possible.
Can I compress scanned PDFs?
Yes, but results may vary because scanned PDFs are usually made of large images.
Is the PDF uploaded anywhere?
No. The compression process runs locally in your browser.
