Split out the pages you need, or try to make a PDF smaller, right in your browser. Your file never leaves your device. Heads-up: browser compression is limited. It works best on scans and photo-heavy PDFs, and it can't match Acrobat's full optimizer.
Your PDF stays on this device. It's processed in your browser and never uploaded.
Digital signatures may not stay valid in split files. Splitting copies the pages into a new file, so a signature on the original no longer covers those bytes.
Keeps everything the same. Savings are often small, and sometimes zero.
Image mode can make a text-only PDF bigger, because a picture of a page is often larger than the original text. If that happens, this page keeps your original.
Need more control? Use Adobe Acrobat.
Acrobat on the desktop. Acrobat's desktop app has Compress a PDF and Split built in, and it processes the file on your computer. Advanced optimization (choosing image, font, and cleanup settings) is in Acrobat Pro, Premium, or Studio on the desktop. Compress & optimize a PDF, Split PDFs, Reduce PDF file size with advanced options.
Acrobat online. Adobe's online Compress PDF and Split PDF tools work in any browser, but they upload your file to Adobe's servers to process it. Adobe says files are deleted from its servers afterward (or kept in your account if you sign in and save). Fine for everyday files; think twice for anything sensitive.
