How to Compress PDF for Email Attachment (Free)

Most email providers (Gmail, Outlook, Yahoo) limit attachments to 25MB. If you have a scanned document or a portfolio with high-res images, it's easy to hit that limit.

Why is my PDF so big?

PDFs are usually large because they contain uncompressed images. A single scanned page can be 5MB-10MB if scanned at high DPI.

The Fix: Images to Optimized PDF

If you have the source images, you can create a perfectly optimized PDF from scratch:

  1. Go to Images to PDF.
  2. Upload your JPGs or PNGs.
  3. Our tool automatically compresses the visual data while keeping the text sharp.
  4. Download a PDF that is often 10x smaller than the original scans.

Privacy Note

Don't upload your bank statements or contracts to shady "online compressors." Our tool runs 100% on your device. Your sensitive documents never leave your computer.
