Initializing Engine...

Why use a dedicated WhatsApp tool?

General purpose tools often fail when you need to meet strict, platform-specific requirements. By using our pre-configured engine for WhatsApp, you ensure your file meets exact dimensions, quality limits, and format specifications automatically.

Zero-Upload Privacy: Unlike other cloud converters, FileCircle utilizes WebAssembly and HTML5 Canvas to process your files directly inside your browser.

Best of all, because FileCircle relies entirely on your browser's local processing power, your files are never uploaded to a cloud server. You get enterprise-grade optimization with 100% absolute privacy.

Platform	Max Document Size	Recommended Format

Frequently Asked Questions

What is the maximum PDF size I can send on WhatsApp?

WhatsApp currently limits document sharing to 16MB on iOS and Android devices. However, WhatsApp Web allows up to 100MB. If you are sending from your phone, you must compress the file to under 16MB.

Is it safe to compress private documents like ID cards?

Yes, the compression runs 100% locally in your browser. Your files are never uploaded to a cloud server, making it completely secure for sensitive personal identification.

Will my PDF still be readable on a smartphone screen?

Absolutely. Our algorithm only degrades background images and metadata, preserving crisp vector text. If you want to send the file as an image instead of a document, use our PDF to Image converter.
