A 12-page scan from iPhone Notes or Files is roughly 15 MB because each page is a 300 DPI colour JPEG. GekiPDF's compress-pdf tool rewrites the file using Ghostscript presets: Light (~200 DPI), Recommended (~150 DPI), or Extreme (~96-120 DPI). Pick Recommended and that same 12-page scan drops to about 1.5 MB – small enough to email or upload anywhere.
Upload your PDF (up to 50 MB per file) and choose a preset. The tool keeps the text layer and removes metadata; it takes about one second for a 16-page scan. You get up to 40 conversions per hour per IP, and files are deleted after one hour. No signup, no watermark – just a smaller file.
Frequently asked questions
Will compressing my iPhone scan make the text blurry?
At Recommended (~150 DPI), text stays readable on screen and for printing drafts. For archiving, use Light (~200 DPI) if you need sharper detail; Extreme (~96-120 DPI) is best for email-only.
Can I compress a scan larger than 50 MB?
No, the free limit is 50 MB per file. If your scan exceeds that, split the PDF first using the split-pdf tool, then compress each part separately.
Does compression remove the searchable text layer?
No, the text layer is kept intact. The tool only downsamples the bitmap images and strips metadata, so you can still search and copy text from the compressed PDF.
