Email systems often reject attachments that are too large. A PDF with scans, photos, or many pages can easily exceed the limit. The solution is to reduce file size while keeping the document readable and complete.
Step-by-Step
- Check the email size limit. Many providers allow around 20 MB to 25 MB, but the practical limit can be lower.
- Open Compress PDF.
- Upload the PDF and create a compressed copy.
- Download the result and check the file size.
- Open the PDF and review text, images, signatures, and page order.
- Attach the compressed copy to your email.
Example
A PDF portfolio may start at 32 MB because it contains full-resolution photos. Compression may reduce it below 10 MB. A scanned legal document may shrink less because each page is already an image and too much compression can make text harder to read.
If Compression Is Not Enough
Remove pages that are not needed with Delete PDF Pages. If the recipient only needs one section, split the document with Split PDF Pages. If the PDF includes image pages, consider converting important pages to images with PDF to JPG only when that format is acceptable.
Before Sending
- Open the compressed PDF.
- Confirm every page is present.
- Zoom in on small text.
- Check signatures and stamps.
- Use a clear filename so the recipient knows what it is.
Privacy Tip
Do not email confidential documents unless email is appropriate for that situation. Remove pages, personal data, or hidden information that the recipient does not need.
FAQ
Why is my PDF still too large?
It may contain high-resolution scans or many image-heavy pages. Splitting or removing pages may help more than compression alone.
Should I zip the PDF?
Zipping may help a little, but PDF compression usually gives better results for image-heavy files.
