PDFOptim

Core tools: PDFOptim provides browser tools to compress, merge, split, rotate and reorder PDF files.
Compression: The compressor can reduce PDF size by up to 90% and is intended for scanned documents, radiographs and photos.
Compression presets: Compression presets are Web at 96 DPI/JPEG 60%, Standard at 150 DPI/JPEG 75% and Print at 200 DPI/JPEG 85%, with a Custom mode.
Vector PDFs: Compress Only mode strips metadata and compresses internal streams without re-rendering, preserving text selectability for software-created PDFs.
Batch processing: Users can drop multiple PDFs for batch compression, and Pro users can download all results as a ZIP file.
Privacy: The web tools run in the browser with JavaScript and WebAssembly, with no file uploads, storage or logs on PDFOptim servers.
Offline use: The web tools work offline after the page has loaded, with internet needed for initial loading and license verification.
Encrypted files: PDFOptim may not be able to compress all password-protected PDFs and recommends removing the password first.
Native apps: RootRise offers native offline PDFOptim apps for macOS, iOS, iPad and Windows.
System requirements: The native apps require macOS 12 or later, iOS 15.6 or later, or Windows 10 or later.
Shortcuts integration: On Mac, PDFOptim can act as a Finder Quick Action through Apple Shortcuts for background compression.
On-device security: The native app processes documents locally, stores information on the device and does not send it to RootRise Technologies or third parties.
Refunds: PDFOptim offers a 30-day no-questions-asked money-back guarantee and says refunds are processed within 24 hours by email.
Price from: $4.99/mo
