Upload your PDF file by clicking the upload area or dragging it in. Choose a compression level — light, balanced, or maximum — and click "Compress PDF". The tool processes your file entirely in your browser, then shows you the original and compressed file sizes. Download the compressed version when ready.
The tool loads your PDF in the browser, removes unnecessary metadata (author, subject, keywords), deduplicates internal objects, and rebuilds the PDF with optimized object streams. All processing happens client-side — your file is never uploaded to any server.
Compression results vary depending on the content. PDFs with large embedded images see the biggest reduction (up to 70-90%). Text-heavy PDFs with minimal images may see 5-30% reduction. The tool shows you exact before/after sizes.
The tool offers three compression levels. "Light" preserves maximum quality with minimal reduction. "Balanced" provides good compression with negligible quality loss. "Maximum" achieves the smallest file size but may slightly reduce image quality.
Yes, 100%. The entire compression process runs in your browser using JavaScript. Your PDF file never leaves your device — nothing is uploaded to any server. Close the tab and the file is gone.
Since processing happens in your browser, the limit depends on your device memory. Most devices handle PDFs up to 50-100 MB without issues. Very large files may take longer to process.
The tool attempts to read encrypted PDFs but may not be able to compress all protected files. For best results, remove the password protection before compressing, then re-add it afterward if needed.
