What is the email attachment size limit?

Most email services limit attachments to 25MB (Gmail, Outlook, Yahoo). Some corporate email systems may limit to 10MB or even 5MB. Use this tool to compress your PDF to fit within these limits.

How much can a PDF be compressed?

Compression results vary based on content. PDFs with many images can be reduced by 50-80%. Text-heavy PDFs with few images may only compress 10-30%. Scanned documents typically see the best compression ratios.

Does PDF compression affect text quality?

No, text in PDFs remains sharp after compression. Our tool primarily compresses embedded images within the PDF. Vector graphics and text are preserved at full quality.

What if my PDF is still too large after compression?

If the compressed PDF is still too large for email, consider: 1) Using a lower quality setting, 2) Splitting the PDF into multiple smaller files using our PDF Split tool, or 3) Using a file sharing service instead of email attachment.

Can I compress multiple PDFs at once?

Yes! Upload multiple PDF files and compress them all in one batch. Each file is independently compressed to the optimal size. Download them individually or use our batch download feature.
