How to compress a PDF online for free?

Compressing a PDF reduces file size by up to 70% with no visible quality loss. FileSwiftly uses Ghostscript, a professional PDF processing engine, to handle your files directly in the browser — no installation or account required.

Three PDF compression levels

Maximum mode shrinks the PDF to the smallest possible size by reducing embedded image resolution — perfect for email attachments. Recommended mode gives the best size/quality balance, ideal for web publishing and presentations. Quality mode applies light compression preserving high fidelity for professional printing.

Which PDF types can be compressed?

Our online PDF compressor supports all standard PDF files: reports, presentations, forms, brochures, eBooks, and invoices. PDFs containing high-resolution images benefit the most from compression. Text-only PDFs see moderate reduction since text is already efficiently encoded in the PDF format.

Security and privacy

Your PDF files are transferred over HTTPS encryption, processed in complete isolation on our secure servers, then automatically deleted after 1 hour. No data is retained, shared, or analysed. FileSwiftly is GDPR-compliant and requires no account.
