Reduce PDF size for everyday sharing
Large PDF files can be difficult to email, upload to portals, or store on mobile devices. PDFVora provides a browser-based compression workflow that processes the file and returns a smaller PDF for review and download.
How PDF compression works
PDF size can come from high-resolution images, repeated resources, embedded fonts, metadata, and page content. Compression may optimize these elements based on the selected processing mode. Documents with many photographs usually have more room for reduction than text-only PDFs.
How to compress a PDF
- Open the compression tool.
- Upload the PDF you want to reduce.
- Start processing and wait for the result.
- Compare the new file size and review important pages.
- Download the compressed PDF.
Choose quality based on the destination
For email and quick previews, a smaller file may be the priority. For printing, legal review, or detailed diagrams, preserve more quality. Keep the original file until you have confirmed the compressed version meets your needs.
Frequently asked questions
Does compression change the number of pages?
Compression is intended to reduce file size without changing the page count.
Why does one PDF compress more than another?
Image-heavy and unoptimized documents often shrink more than PDFs that already use efficient compression.
Can compression reduce image quality?
It can, depending on the processing level and document content. Review photographs, charts, and small text before sharing.
Can I compress a password-protected PDF?
Protected files may need to be unlocked with the correct password before processing.
Should I keep the original PDF?
Yes. Keep an original copy until you verify the compressed document.
