PDF
Re-package a PDF to reduce its file size — handy for email attachment limits or faster uploads. Works best on text-heavy documents; PDFs full of high-resolution images will see a smaller reduction. Add several PDFs to batch-compress them into one zip.
How to use Compress PDF
- Upload the PDF you want to shrink.
- Tap Run — no settings to configure.
- Download the compressed file and compare the size difference.
FAQ
Why didn't my file get much smaller?
PDFs made mostly of embedded photos or scanned images don't compress much this way, since the size is dominated by image data rather than document structure — this tool optimizes structure, not image quality.
Does compressing reduce text or image quality?
No — this is a lossless structural optimization; the visible content of every page stays exactly as it was.
