What is the PDF file size limit on WhatsApp?

WhatsApp allows documents (including PDFs) up to 100MB. However, sending very large files over mobile data is slow and may fail on poor connections. Keeping your PDF under 20–30MB ensures fast, reliable delivery.

Can I compress a PDF to send on WhatsApp from my phone?

Yes. FixTools works in any mobile browser — Safari on iPhone and Chrome on Android. You can upload, compress, and download the PDF entirely from your phone without installing any app.

Will WhatsApp compress the PDF further when I send it?

WhatsApp does not re-compress PDF files the way it compresses images. What you send is exactly what the recipient receives, so pre-compressing ensures a predictable file size.

What if my PDF is larger than 100MB after compression?

If even high compression cannot bring a very large PDF under 100MB, use the PDF Splitter to divide it into smaller parts and send each part as a separate WhatsApp message.

Is it safe to compress personal documents for WhatsApp?

Yes. FixTools processes your PDF entirely in your browser — no file data is sent to any server. The compression happens on your device, so your document stays completely private.

Can I compress PDFs to send in WhatsApp Business?

Yes, WhatsApp Business has the same 100MB document limit as the consumer app. The same compression workflow applies.

Compress PDF for WhatsApp

WhatsApp enforces a 100MB limit on document files. While most PDFs stay under this, scanned reports, presentations, or photo-heavy documents can easily exceed it. FixTools compresses your PDF in the browser so you can send it over WhatsApp without hitting the limit — and without installing any extra app.
