Optimize PDFs in three steps
Load Files
Drop PDFs or entire folders. The app shows the current file size for each document so you can see the starting point.
Choose Profile
Select a compression profile: Web (maximum compression), Balanced, Print (high quality), or Custom. Each profile preconfigures image resolution, compression, and font handling.
Compress & Compare
Click optimize and watch file sizes shrink in real time. A before/after comparison shows exactly how much space you saved per file and in total.
Key Capabilities
Intelligent PDF compression
Compression Profiles
- Web — maximum compression for online distribution
- Balanced — good compression with readable quality
- Print — minimal compression for print-ready output
- Custom — full control over every parameter
- One-click profile selection for fast processing
Optimization Techniques
- Image downsampling to target DPI
- JPEG and lossless image recompression
- Font subsetting — embed only used characters
- Remove duplicate objects and unused resources
- Linearization for fast web viewing
Before/After Comparison
- Original and optimized file size displayed per file
- Percentage reduction shown for each document
- Total batch savings calculated automatically
- Identify which files benefited most from optimization
- Detailed operation log with compression statistics
Batch Processing
- Optimize hundreds of PDFs in a single operation
- Same profile applied consistently to every file
- Real-time progress tracking
- Output to new directory or overwrite originals
- Chain with merge, sign, or PDF/A in a pipeline
Use Cases
When file size matters
Email Distribution
A marketing team needs to email 200 product catalogs. Each PDF is 15 MB — too large for most email servers. Batch optimize with the Web profile brings them down to 3 MB each.
Web Upload
A government agency publishes 500 annual reports on their website. Optimized PDFs load faster for citizens, reduce hosting bandwidth costs, and meet accessibility performance targets.
Archive Storage
A company archives 10,000 scanned documents annually. Optimizing with the Balanced profile reclaims 60% of storage space without sacrificing readability for future retrieval.
Frequently Asked Questions
Will optimization reduce the visual quality of my PDFs?
It depends on the profile you choose. The Print profile maintains high quality with minimal compression. The Balanced profile offers a good tradeoff. The Web profile prioritizes file size reduction, which may lower image resolution. You always see a before/after comparison to verify the results.
What techniques does the optimizer use?
The optimizer applies image downsampling and recompression, font subsetting (embedding only the characters actually used), removal of duplicate objects and unused resources, and stream compression. The Custom profile gives you granular control over each technique.
Can I see how much space I saved?
Yes. After processing, the app shows original and optimized file sizes for every file, the percentage reduction, and a total batch savings summary. The operation log provides detailed compression statistics.
