Compress PDF for WhatsApp — Fast, Free, Browser-Only
Overview
WhatsApp allows document sharing up to 100MB. For most PDFs this is enough, but scanned documents, high-resolution brochures, and multi-page reports can easily exceed that. PDF Mavericks compresses your PDF in your browser — no app, no data sent to a server, and it works on Android and iPhone browsers too.
How to Use This Tool
Open PDF Mavericks on your phone or desktop browser. Tap to upload your PDF, choose your compression level, and download the compressed file. Then share it directly via WhatsApp. The whole process takes under 30 seconds for most files.

What is WhatsApp's PDF file size limit?
WhatsApp supports document sharing up to 100MB per file. For PDFs larger than this, you need to compress or split them before sharing.
Can I compress a PDF on my phone?
Yes. PDF Mavericks runs entirely in your mobile browser — Chrome or Safari on iPhone or Android. No app download required.
Does compressing a PDF affect how it looks when shared?
At 'Low' or 'Medium' compression, the difference is undetectable. At 'High' compression, images may show slight softening, but text remains sharp.
