How It Works
Step 1: Upload Your PDF
Drag and drop a PDF up to the browser uploader limit (currently 150 MB).
Step 2: Choose an Outcome
Choose Maximum reduction, Strong reduction, Balanced, or Best clarity. Actual savings depend on the PDF.
Step 3: Download the Result
Review the measured result, then download one PDF or a ZIP from the local multi-file workflow.
Why Use This Tool
- Four outcome presets with clear size-versus-clarity trade-offs
- Free local multi-file processing with one ZIP download
- No watermark, account requirement, or daily task counter
- Selected PDFs are processed locally and are not uploaded by this workflow
Common Use Cases
Compress PDF files for email attachments, cloud storage, website uploads, and portal submissions. Use the exact-size links when a portal states a strict limit. After this page and its local PDF engine have loaded, the selected documents are processed in the browser rather than uploaded by the compression workflow.

Frequently asked questions
How do I compress a PDF to under 100KB?
Upload your PDF, select "Extreme" compression level, and click Compress. Our tool can reduce most PDFs to under 100KB while maintaining readability.
Is my PDF secure when compressing?
Yes! ExactPDF processes all files locally in your browser. Your PDF never leaves your device - we never upload or store your documents.
Can I compress multiple PDFs at once?
Yes! Toggle "Batch Mode" to compress multiple PDF files simultaneously. All processing happens locally on your device.
Will compression reduce PDF quality?
You control the quality-size tradeoff. Choose from 4 compression levels: Low (best quality), Medium (balanced), High (good quality), and Extreme (smallest size).
Does this work offline?
Compression runs locally in your browser, so your PDF is not uploaded. Offline use requires the PDF engine to be prepared while you are connected, and it depends on your browser keeping that resource available.
