PDFOptim
What PDFOptim is
PDFOptim provides browser tools and native apps to compress, merge, split, rotate and reorder PDF files. Its compressor can reduce file size by up to 90%, with Web, Standard, Print and Custom presets. Compress Only mode strips metadata and compresses internal streams without re-rendering, preserving selectable text for software-created PDFs. The browser tools use JavaScript and WebAssembly; PDFOptim says files are not uploaded, stored or logged on its servers. They can work offline after the page loads, though initial loading and license verification require internet access. Users can compress multiple PDFs in a batch, while downloading all results as a ZIP is available to Pro users. The free plan costs nothing and allows three operations per day on files up to 25 MB. Pro Monthly costs $4.99 a month and supports unlimited operations and files up to 200 MB; Lifetime costs $19, paid once. Native offline apps for macOS, iOS, iPad and Windows process documents locally. Mac users can also use Apple Shortcuts for background compression.
