How to Reduce PDF Size for Email | Bsbshs

Open the tool →

Email services usually cap attachments at around 25 MB, and many inboxes choke well before that. If your PDF won't send, here's how to reduce its size for email while keeping it readable — privately, in your browser.

Why your PDF is too big to email

PDFs balloon when they contain high-resolution images or scanned pages. A few photographed pages can easily exceed the limit. Reducing the image data inside is what brings the file back under the cap.

How to reduce a PDF for email

  1. Open a PDF compressor and add your file.
  2. Compress it, or set a target size if you have a specific limit.
  3. Preview to confirm it's still readable, then download and attach.
If it's still too big, split the PDF and send it in parts, or remove pages you don't need before compressing.

Other ways to shrink it

Keep it private

Emailed PDFs are often personal or work documents. A browser-based compressor keeps the file on your device, so it's never uploaded to a third-party server just to shrink it.
