Frequently Asked Questions

How are my PDF documents kept secure?

FileVeda uses client-side rendering engines (via WebAssembly and Canvas). Your documents are parsed and compressed completely inside your browser's local RAM. No file data is transmitted across the internet to our backend.

Will compressing my PDF reduce text readability?

Our Recommended and Low compression algorithms optimize embedded streams and downsample background image noise while preserving sharp font legibility. For documents with strict size caps, the Extreme setting reduces DPI to ensure the file fits under strict quotas.

Can I compress multiple PDFs at once?

Yes! You can drag and drop multiple PDF files simultaneously. Each document is compressed in sequence and you can download them individually or all at once.
