Why compress PDFs for WhatsApp?
Even if a platform allows large document sizes, huge PDFs are still annoying: slow upload, slow download, and failures on poor connections. Smaller PDFs simply work better.
- Send PDFs faster on WhatsApp chats and groups (especially on mobile data)
- Great when recipients can’t download big files reliably
- Compact mode keeps text sharp; Rasterize hits smaller sizes for scans
- No signup, no watermark — download instantly
- Works on iPhone/Android/desktop browsers
Built for mobile sharing
Compress first, then share. Targets like 500KB or 1MB feel instant compared to large scans.
For scanned PDFs, Rasterize mode usually achieves the biggest reductions.

Compress PDF for WhatsApp — FAQs
Do I need to compress a PDF for WhatsApp?
Not always, but compression helps your PDF send faster and download reliably—especially for large scanned PDFs or when sending to groups.
What size should a PDF be for WhatsApp sharing?
WhatsApp limits vary by how you send the file and platform. For maximum compatibility and fast delivery, keep PDFs as small as possible (often 1MB or 500KB is a great target).
How do I keep quality while compressing?
Use Compact mode first. If you’re sending a scanned PDF and need a much smaller file, use Rasterize and lower DPI/quality gradually.
Is my PDF uploaded to your servers?
Yes for compression. Your PDF is transferred over encrypted TLS to our compression backend and Adobe PDF Services for processing. Avoid uploading extremely sensitive documents.
