PDF optimization reduces file size by restructuring the internal object streams, removing duplicate resources, and eliminating unnecessary data embedded during creation.
This tool works best on:
Standard Optimization restructures the PDF's internal object streams for more efficient storage. This preserves all metadata, fonts, and document properties.
Maximum Optimization includes all Standard features plus removes embedded metadata like author info, creation dates, and application stamps for the smallest possible file.
Tip: Use Standard for documents you'll share professionally. Use Maximum for personal archiving or when file size is critical.
Simply drag and drop your PDF file onto the upload area above, or click to select a file. Choose your optimization level (Standard or Maximum), then click "Optimize All." Your optimized PDF will be ready to download in seconds — all processed locally on your device with no uploads required.

Results vary depending on how the original PDF was created. PDFs exported from design software (like InDesign or Canva) often see 20-60% size reduction. Already-optimized PDFs may see minimal changes. The tool shows the original and optimized file sizes so you can see exactly how much space you saved.
No. This tool focuses on structural optimization — it reorganizes how data is stored inside the PDF without altering the actual content. Text remains crisp, images stay at their original quality, and all visual elements are preserved exactly as they were.
Absolutely not. Your PDF files are processed entirely in your web browser using JavaScript. Nothing is ever uploaded to any server. We have no ability to see, access, or store your documents. This makes our tool ideal for sensitive, confidential, or legally protected documents.
Yes! You can select multiple PDF files at once or add files one at a time. Click "Optimize All" to process the entire batch, then use "Download All (ZIP)" to get all your optimized files in a single convenient archive.
