Why pick Convertify for this?
Files stay on device
Convertify processes everything in your browser using JavaScript. Your file is never uploaded — confirm with DevTools → Network. That makes this safe for sensitive material like contracts, IDs, and financial documents.
No upload wait
Because nothing uploads, processing starts the instant you click. For typical files (under 50 MB) the whole job finishes in seconds — no progress bar, no queueing behind other users.
No daily quota
Free without limits, including no "3 conversions per day" cap that competing services impose. Run as many compress pdf jobs as you need.
No watermark
Your output is clean — no Convertify branding, no metadata stamp. Same as if you'd run a paid desktop app.

Frequently asked questions
What is WhatsApp's document size limit?⌄
WhatsApp lets you send documents up to 2GB on current versions, but smaller files send faster and use less of the recipient's data — compression helps both.
How do I compress a PDF for WhatsApp?⌄
Upload your PDF, pick a compression level, and download the smaller file. Then attach it as a document in any WhatsApp chat.
Why should I compress before sending on WhatsApp?⌄
Smaller files upload and download faster, especially on mobile data, and avoid failed sends on slow connections.
Can I compress on my phone?⌄
Yes. Open Convertify in your phone's browser, compress the file, then share it through WhatsApp — no app needed.
