How much will compression reduce my file size?

Results vary based on content. PDFs with many images can see 50–80% reductions. Text-heavy PDFs typically see 20–40% reduction. The High preset delivers the maximum possible reduction for any given file.

Is my PDF secure during cloud processing?

Yes. Your file is encrypted via TLS during upload and processing. FileVelo's cloud engine permanently deletes both the original and the compressed file immediately after you download the result. There is no retention or logging.

What is the difference between the Low, Medium, and High compression levels?

Low optimises internal file structure with minimal visual impact — best for archiving. Medium applies balanced compression to images and fonts — ideal for most use cases. High applies maximum compression for the absolute smallest file size.

How to Compress a PDF with FileVelo

Large PDFs clog email inboxes, break upload limits on document portals, and consume unnecessary storage. FileVelo's Compress PDF tool slashes file sizes using a professional cloud compression engine — the same technology trusted by businesses to optimise documents at scale, now available free with a single click.

FileVelo offers three compression presets tuned for different needs. Low preserves near-perfect visual quality while trimming redundant internal structures — ideal for archiving documents where quality cannot be compromised. Medium applies balanced compression across images and fonts, typically reducing file size by 40–70% without perceptible quality loss — the right choice for most everyday documents. High applies maximum compression, delivering the smallest possible file size — best when you need to share by email or upload to a portal with strict size limits.

Every byte of your document is protected in transit by TLS encryption. Once FileVelo's cloud engine completes compression and delivers the download, both the original and processed files are permanently deleted — not archived, not logged, not retained. Your data exists on our infrastructure for seconds, not hours. There is no human review, no data mining, and no retention of any kind.

FileVelo's compression engine is powered by CloudConvert, a trusted document processing platform handling millions of conversions daily. The result is a standards-compliant PDF that opens cleanly in every viewer — smaller, sharper, and ready to share wherever you need it.
