Frequently asked questions

Why should I compress a PDF before uploading it?

Compression helps when portals, email systems, or clients have file-size limits. It can make tender submissions and compliance uploads smoother.

Will compression change the original PDF?

TenderPDF creates a processed download. Keep your original file safe and review the compressed version before using it for important submissions.

Is PDF compression useful for scanned files?

Yes. Scanned PDFs are often large, so compression is useful before emailing, archiving, or uploading them.
