Common Interrogatories

Expert Knowledge Base Resolved

Why is my PDF too big to email?

Most email providers like Gmail, Outlook, and Yahoo have a strict 25MB attachment limit. High-resolution images and embedded fonts often push PDFs over this limit. PdfXpo compresses these elements without visible quality loss, making your files email-ready instantly.

How do I make a PDF small enough for a 25MB attachment limit?

By using PdfXpo's 'Standard Efficiency' mode, our tool automatically balances image DPI and compression ratios to target sizes under 25MB. Simply upload your over-sized PDF, and within seconds, you'll have a version that fits perfectly into any standard email composer.

Will my recipient still be able to read and print the smaller PDF?

Yes. Our compression engine prioritizes text clarity and vector sharpness. Even when file sizes are reduced by 90%, the text remains crisp and the layout stays intact. Your recipient will be able to read, search, and print the document just like the original.

Is it safe to shrink sensitive work documents for email?

Your privacy is paramount. PdfXpo processes all documents locally in your browser using WASM technology. Your sensitive business or personal files are never uploaded to our servers, making it the most secure way to prepare attachments for email.
