Compression re-renders PDF pages as images. Searchable text, links and form functionality may be lost. PDFs that are already well compressed can end up the same size or larger.
Compress PDF: how it works
Choose a quality level. This works best for scanned or image-heavy PDFs.
FAQ
Will text remain searchable?
This compression rebuilds pages as images, so searchable text, links and forms may be lost.
Will every PDF become smaller?
No. Already optimised or mostly vector-based PDFs may stay the same size or become larger.
Which level should I use?
Balanced is a good starting point. Strong reduces resolution more aggressively.
Your PDFs stay on your device.
Many online PDF services upload documents to a server for processing. LocalPDF takes a different approach: the actual document processing happens in your browser. This is especially useful for invoices, contracts and other sensitive documents.
Note: JavaScript libraries used for PDF processing are loaded from external CDNs. Your IP address may therefore be transmitted to the CDN provider, but your PDF files themselves are not transmitted.
