Compress PDF on iPhone
The PDF is on your iPhone and the portal deadline is now. Compress it right in Safari — Files app in, smaller file out, exact KB targets included. No app download. We compress toward your target at the best quality that fits, never make the file larger than the original, and always show the real final size — very image-heavy files may land slightly above tight targets.

The iPhone flow
Open the tool in Safari, tap upload, pick the PDF from Files (or straight from a Mail attachment via Share → Save to Files), compress, and the result lands in Downloads. The whole loop runs on the phone you are holding.
Phone scans are the classic case
iPhone Notes and camera scans produce beautiful, enormous PDFs — 10MB for three pages is normal. Those files are precisely what compression eats: expect dramatic reductions at readable quality.
