How do I compress a PDF file for email?

Use our free PDF compressor: upload your PDF, click compress, and download the smaller file. Most email providers limit attachments to 25MB or less. If your compressed PDF is still too large, consider sharing it via Google Drive or Dropbox.

Why is my PDF file so large?

PDFs can be large due to high-resolution images, embedded fonts, or unoptimized content. Our tool compresses images and optimizes the PDF structure to reduce file size while keeping text and layout intact.

Will compressing a PDF reduce quality?

Our compressor is designed to minimize quality loss. Text stays sharp, and images are optimized for a good balance between file size and visual quality. For best results, avoid compressing PDFs that are already heavily compressed.

Can I compress a PDF without installing software?

Yes. Our PDF compressor runs entirely in your browser. No download or sign-up required. Just upload, compress, and download.

Are my PDF files handled securely?

Yes. Uploaded PDFs are stored fully encrypted and are not shared with any third party. We automatically delete files that have not been accessed for a while.

Is there a file size limit for PDF compression?

Our free PDF compressor supports common file sizes for typical documents and presentations. For very large files, try splitting the PDF or compressing in batches.
