Merge, compress, and shrink PDFs right here in your browser. Free, instant, and completely private — nothing is ever uploaded.
Repacks the PDF's internal structure without touching pages, text, or image quality. Great for text-heavy documents; photo-heavy PDFs shrink less — use Shrink to size for those.
Yes. Everything runs in JavaScript inside your browser tab. Your files are read into memory on your own device, processed there, and never uploaded, stored, or transmitted anywhere. Close the tab and they're gone. You can even load this page, disconnect from the internet, and it still works.
Compress is lossless: it repacks the PDF's internal structure so nothing about the content changes — same text, same image quality. Savings are modest but free. Shrink is lossy: it re-renders pages as compressed images to hit a target file size. It saves far more space, but text stops being selectable and fine detail is reduced.
