Compress any PDF so it sends instantly on WhatsApp. Works on iPhone, Android and WhatsApp Web. No signup, no watermark, completely free.
Files deleted after 2 hours · 100% secure
WhatsApp allows document files up to 100MB. However, large PDFs load slowly on mobile data and can fail to send on poor connections. Compressing to under 10MB ensures fast, reliable delivery on all network speeds.
If your PDF exceeds 100MB, WhatsApp will reject it. Compress it with PDFTash first — most PDFs shrink by 70–90%, bringing even large files well within WhatsApp's limit.
Open pdftash.com/reduce-pdf-size-for-whatsapp in your mobile browser (Safari or Chrome). Upload your PDF, download the compressed version, and share it in WhatsApp. No app download needed.
Yes, if it's under 100MB. But for fast delivery and to avoid failures on slow connections, compressing to under 10MB is strongly recommended for group chats and business use.
