Compress PDF for WhatsApp (Under 100MB)
WhatsApp document limit is 100MB. Anything over and your PDF won't send. Here's the 30-second fix.
WhatsApp lets you share PDFs up to 100MB as documents. Larger files get rejected with no useful error message. Compression in your browser solves it without uploading sensitive documents to random websites.
Open PDF CompressorStep-by-step
Check your file size first
Right-click the PDF on your device and check properties. If it's over 100MB, you need compression. Under 100MB, the issue is something else (try resending or checking your connection).
Open the PDF Compressor
Launch the tool. Works on phone, tablet, or desktop browsers.
Choose 'Medium' compression
For WhatsApp, medium compression usually gets you well under 100MB while keeping the document readable. Try high compression only if medium isn't enough.
Download and share
Save the compressed file, open WhatsApp, attach as document. It will send normally.

Open PDF CompressorFrequently asked questions
What is WhatsApp's PDF size limit?
WhatsApp allows documents up to 100MB. This applies to PDFs, Word files, Excel files, and other document types. Media (photos, videos) have separate, smaller limits.
Will the recipient see the same document?
Yes. A compressed PDF retains all text, layout, and pages — just with slightly smaller embedded images. It looks and reads the same when opened.
Can I send compressed PDFs in WhatsApp Business?
Yes. WhatsApp Business uses the same 100MB document limit. Compressed files send identically.
Why is WhatsApp showing 'file too large' even after compression?
Some older Android versions cap shared attachments lower. Update WhatsApp or try sharing from a different device. If the file is under 100MB and still fails, your data connection may be timing out — try Wi-Fi.
