LinksConverterCompress PDF
Shrink a large PDF so it is easy to email, upload to a portal, or store. We downsample embedded images and strip waste while keeping the text sharp and the layout identical. If a PDF is already optimised, we hand it back untouched rather than making it bigger.
When to use Compress PDF
- Get a PDF under an email or upload size limit
- Speed up sharing of image-heavy scans and brochures
- Save storage on a large archive of documents
- Attach a report to a form that caps file size
