How to Split and Compress a Large PDF of Photos for Email
Question details
The user needs to reduce the file size of a large PDF containing around 150 photos to send it via email, specifically by dividing it into smaller groups of pages.
- Product
- Device & OS
- not provided
- Scenario
- Attempting to send a large PDF file containing multiple photos via standard email attachments.
- Observed behavior
- The PDF remains over 30 MB even after standard compression, making it too large to attach to standard emails.
Before splitting or compressing your document, ensure you have saved a backup copy of the original large PDF so you do not accidentally overwrite or lose any of your high-quality photos.
Split the Large PDF into Multiple Smaller Files
Divide the 150-page photo PDF into smaller sections (e.g., 50 pages each) to easily attach them to separate emails.
Images typically take up the most space in a PDF. Because excessive compression can noticeably degrade image quality, splitting the document into smaller parts is often the most reliable way to meet email attachment limits while preserving photo resolution.
Launch your preferred PDF editing software, such as Adobe Acrobat or WPS Office, and open the large PDF file.
Navigate to the 'Organize Pages' or 'Page' tab and select the 'Split PDF' tool.
Choose the option to split the document by 'Number of Pages' and enter '50' to divide your 150 photos into three separate files.
Select your desired output folder and click 'Split' to generate the smaller, email-friendly PDF files.
Share the Large PDF via a File Transfer Service
Bypass email attachment limits entirely by uploading the large PDF to a secure cloud transfer service and sharing a download link.
Use WPS Office to Split and Compress Your PDFs
WPS Office provides built-in, easy-to-use tools to quickly split large PDFs by page count or file size, and offers advanced compression options without severely degrading image quality.
- 1. Open your PDF: Launch WPS Office and open your large photo PDF.
- 2. Select the Split tool: Navigate to the 'Page' tab on the top ribbon and click on 'Split PDF'.
- 3. Configure split settings: Choose to split the document by page count, entering a specific number (e.g., 50 pages per file), and designate your output directory.
- 4. Compress the split files: If the split files are still slightly too large for email, use the 'Compress' tool under the 'Tools' tab to optimize their size further.
Frequently Asked Questions
Why is my PDF still so large after compressing it?
Photos and high-resolution images hold a massive amount of data. PDF compression tools reduce size by lowering image resolution or quality. If your PDF is almost entirely photos, standard compression may not be able to drop it below email limits without making the photos noticeably blurry.
What is the maximum file size I can send via standard email?
Most standard email providers, such as Gmail, Outlook, and Yahoo, have a strict attachment size limit of 20 MB to 25 MB per email. If your file exceeds this limit, it will either be blocked or automatically converted into a cloud drive link.
Will splitting my PDF reduce the quality of the photos?
No. Splitting a PDF simply separates the existing pages into entirely new documents. It does not compress, alter the resolution, or reduce the quality of the images contained within those pages.
Can I extract just a few specific photos from the PDF instead of splitting the whole file?
Yes. Using a capable PDF editor like WPS Office, you can select the 'Extract Pages' option. This allows you to pull out only the specific pages containing the photos you want to share, saving them as a new, much smaller PDF file.
