Compress PDF
Compress PDF files in your browser — free, no upload, no limits. Best for scanned or image-heavy PDFs, where it dramatically reduces file size on your device.
Your file never leaves your device — there's no upload step at all. You can verify it: open your browser's DevTools → Network tab and watch as you use the tool. Zero file uploads.· Updated June 2026.
No AI can shrink a file it never receives. Yours never leaves this tab.
How this works
Use the tool locally, download the result, and contact VNG only when this needs to become a repeatable workflow.
How it works
- 1
Choose a PDF
Pick a PDF — especially a scanned or image-heavy one. It loads locally, no upload.

Frequently asked questions
How does it compress the PDF?
It re-renders each page as a compressed image at a lower resolution, then rebuilds the PDF. This is very effective for scanned documents and image-heavy PDFs.
Will the text still be selectable?
No — because pages are rebuilt as images, selectable text and form fields are flattened. Use this when smaller size matters more than text selection. For text-only PDFs, savings are smaller.
Are my files uploaded?
No. Everything happens in your browser with PDF.js and pdf-lib. Check DevTools → Network — nothing is sent.
Is there a limit?
No daily limit. Large PDFs use more memory since processing is local; very big files may be slow on phones.
