Batch Compress PDF Files
- Simultaneous compression of multiple PDF files. Make most use of processor cores to compress PDF files at amazingly fast speed.
- Just follow three easy steps to export images
- Add PDF files into list.
- Choose compression mode.

Auto Compression Mode
- PDFOptim analyze document’s contents and apply algorithm to generate a smallest possible PDF by maintaining the document’s visual quality. Choose one of the four predefined Auto compression methods and let the app do the hard work for you. No further user interaction required to provide technical compression options.
Manual Compression Mode
- Change compression options manually to generate optimum sized PDF of your need.
- Use predefined presets or customize options as new preset.
- Quartz and Graphics filters. Powerful and robust Graphics filter can compress PDF document without losing document’s integrity and preserves PDF document properties.
- JPEG compression with quality control.
- Colorspace conversion to RGB, CMYK, Gray and Bitonal color profiles. Use Bitonal for black & white image. Very efficient for scanned PDFs.
- Downsampling at lower resolution decrease the file size dramatically.
- Optimize vector graphics option removes superfluous information to reduce vector graphics heavy PDF.
Side-by-side PDF comparator

- Synchronized PDF page preview navigation and magnification controls
- Preserves compressed PDF files for different compression options help you choose desire PDF.
Automation Integration
- Automate your workflow using PDFOptim Shortcuts Actions. It's a quick way to compress PDF. Install given ready-made shortcuts or create your own powerful task automations combining PDFOptim action and actions across multiple apps in Shortcuts app.
- Two ready-made shortcuts “PDFOptim Auto Compress.shortcut” and “PDFOptim Compress.shortcut” to use it as Finder Quick Action to create compressed PDF file besides original file in Finder.
Other Features
- Three destination path options to export compressed PDF files - Replace Original, Ask destination folder on export and Set default destination folder.
- Drag & Drop out to export compressed-PDF files onto other applications like Finder, Mail, Preview etc.
- Many flexible add file options beside direct Add File/Folder buttons. Like Simply Drag & Drop into list or Right click & Open With in Finder or Drop files on "PDFOptim" application to add files into list for conversion.
- Option to maintain source folder structure hierarchy at destination with compressed files in respective folders.
- Option to preserve creation and modification date of original PDF to compressed PDF.
Compressed PDF documents requires less disk space for storage and faster uploads and downloads saves transmission time and cost. The PDFOptim gives you access to compression filter options to help you to reduce PDF file size without compromising the document's integrity. PDFOptim rewrites the entire PDF documents using selected compression filter as efficiently as possible. Some PDF documents might not get compressed, because the PDF documents might be already compressed or have nothing much to compress.
For iPad
PDFOptim is a simple and intuitive way to compress, optimize and reduce PDF documents on iPhones and iPads. PDFOptim provides easy and effective ways to compress large image heavy PDF files. Inbuilt side-by-side preview to compare original and compressed PDF.
Auto compression mode
- PDFOptim analyze document's contents and apply algorithm to generate a smallest possible PDF by maintaining the document's visual quality. Choose one of the four predefined Auto compression methods and let the app do the hard work for you. No further user interaction required to provide technical compression options.
Manual compression mode
- Options to set from JPEG Image Quality, Image Resolution, Image Color Model, Optimize vector and Advance options.
