How to Compress a PDF for Emailing Using Adobe Services
Question details
The user needs to reduce a PDF's file size for emailing after purchasing an Adobe ExportPDF subscription, but is prompted to pay an additional fee for Acrobat's compression tools.

- Product
- Adobe ExportPDF
- Device & OS
- not provided
- Scenario
- Trying to email a large PDF document but encountering file size limits, requiring PDF compression.
- Observed behavior
- Adobe ExportPDF successfully converts files but does not offer a compression feature, prompting an upgrade request to Adobe Acrobat for an additional fee.
Before modifying your original PDF, it is recommended to save a backup copy of the document. Check the maximum attachment size limit of your email provider (typically 20MB to 25MB) so you know your target file size.
Compress the PDF using Adobe Acrobat
Adobe Acrobat Pro or Standard is required to natively compress PDF files within the Adobe ecosystem.
Adobe ExportPDF is exclusively designed for file conversion and lacks compression tools. To reduce file size natively, you need Adobe Acrobat, which offers a dedicated optimization feature.
Launch Adobe Acrobat on your computer and open the large PDF file you wish to compress.
Navigate to 'File' in the top menu, select 'Save as Other', and then click on 'Reduced Size PDF'. Alternatively, you can go to 'Tools' and select 'Optimize PDF'.
Choose your desired version compatibility settings from the drop-down menu and click 'OK' to save the newly compressed PDF for emailing.

Share the Large PDF via Adobe Send
Bypass strict email size limits by sending a secure download link to the large PDF instead of attaching the file directly.
Request an Adobe Subscription Change
If ExportPDF does not meet your needs, Adobe Support can assist with upgrading your plan to Acrobat or processing a refund.

Frequently Asked Questions
Why can't I compress a PDF with Adobe ExportPDF?
Adobe ExportPDF is a specialized service designed strictly for converting PDFs to editable formats like Word, Excel, or RTF. It does not include tools for reducing file size or optimizing PDFs.
What is the typical email attachment size limit?
Most major email providers, such as Gmail and Outlook, restrict file attachments to 20MB or 25MB. If your PDF exceeds this limit, you must compress the file or share it using a secure cloud link.
Does compressing a PDF reduce its visual quality?
Compression usually downsamples embedded images and optimizes document data. While it drastically reduces file size, heavy compression might make high-resolution images look slightly blurry. However, standard text generally remains perfectly readable.
Can I compress a PDF for free without buying Adobe Acrobat?
Yes. You can use the 30-day free trial of Adobe Acrobat, utilize trusted free online PDF compressors, or download a free lightweight software alternative like WPS Office to easily compress your documents.
