ShrinkPDF

什麼是 ShrinkPDF？

ShrinkPDF is a set of 7 free PDF tools (compress, merge, split, rotate, convert to images, reorder pages) that run entirely in your browser. Nothing is ever uploaded to a server, which matters when you're compressing a payslip, tax filing, or signed contract. No signup, no file size caps, no watermark, no premium tier. Open the page, drop your file, and it's processed instantly on your own device using pdf-lib, an open source library.
