Compress PDF Locally

Reduce scanned or image-heavy PDFs by rendering pages locally, downsampling them and rebuilding a new PDF. This is true visual compression, not a fake metadata-only pass.

Compress

Visually compress PDFs through local page rasterization.

Render pipeline guardedpdf.js uses its own parsing worker; canvas export is paced with UI yields and large preview protection.

Compression preset

Visual compression rasterizes pages into JPEG layers. It can substantially reduce scanned PDFs, but selectable text and vector detail may not be preserved.

Shortcut: Cmd/Ctrl + Enter

Scans and image-heavy PDFs

Be honest about rasterization, selectable text loss and image extraction limits.

Audience: people handling receipts, scans, reports and application packets
Primary intent: convert images, export PDF pages and reduce large scanned PDFs

faq

Practical boundaries before you process a file.

Is this real PDF compression?

Yes for scanned or image-heavy PDFs: pages are rendered, downsampled and rebuilt as compressed JPEG layers. Text/vector fidelity may not be preserved.

Will selectable text remain selectable?

Not in visual compression mode. VaultPDF labels this clearly because the output is page imagery inside a PDF.
