PDF Compression Tool

Our PDF compressor uses advanced algorithms to reduce file size by optimizing images, removing redundant data, and compressing the PDF structure. The tool maintains document quality while significantly decreasing file size, making it perfect for email attachments or web uploads.

Yes, the current maximum file size is 50MB. This ensures optimal performance and prevents browser crashes when processing very large files. For files larger than 50MB, we recommend splitting them into smaller parts before compression.

Absolutely! All processing happens directly in your browser - we never upload your files to any server. Your documents remain completely private and are deleted from memory as soon as you close the page or download the compressed version.

Our compression is designed to be lossless for text and vector graphics. For images, you can control the compression level to balance between file size and quality. The tool provides a preview so you can verify the results before downloading.

Currently, our tool processes one PDF at a time for optimal performance. For batch processing, you can compress files one after another or consider our premium version which offers batch processing capabilities.

PDFs with high-resolution images, scanned documents, and files with embedded fonts see the most significant size reduction. Text-heavy documents with minimal images will see smaller but still noticeable improvements.
