PDFOptim review
A flexible PDF compressor with previews, batch processing, and cross-platform coverage.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PDFOptim is a PDF compression product with browser-based tools and native applications for macOS, iOS, and Windows. It is designed for users who need to reduce PDF sizes across devices, compare output quality before saving, or process multiple files. The product supports scanned-document optimization, vector graphics optimization, metadata and structural stripping, and local processing on the device or in the browser without uploading documents. Apple Shortcuts automation adds a workflow option for supported Apple environments.
The pricing structure covers occasional and recurring use. The Free plan costs $0 forever and includes 3 operations per day, files up to 25 MB, and all four browser PDF tools. The Lifetime plan costs $19 as a one-time purchase and adds unlimited operations, files up to 200 MB, batch ZIP download, and future tools. Pro Monthly costs $4.99 per month and includes unlimited operations, files up to 200 MB, and batch ZIP download. Native app prices may differ by store and region, so the website plans are clearest for comparing the core options.
PDFOptim’s main strength is control over the compression process. Web, Standard, Print, and Custom presets provide different starting points, while re-render mode targets scanned PDFs and compress-only mode targets vector PDFs. Side-by-side previews make quality tradeoffs visible, and native batch processing supports larger workflows. The product fits users who want previews and broad platform coverage rather than a single-purpose desktop utility. It may be less suitable for teams seeking extensive third-party integrations, or for workflows involving files above 200 MB.
