Common questions (4)
What's WhatsApp's document size limit?
WhatsApp caps documents at 100 MB. Files larger than this are rejected when you try to attach them in a chat.
Why does fits. compress my PDF below the WhatsApp limit?
Smaller files send faster and use less mobile data on the receiver’s side. We compress for quality + practicality, not just to barely fit the ceiling.
Is it safe to compress confidential PDFs here?
Yes. Your file never leaves your browser. fits. has no server-side component for document handling — compression runs in WebAssembly on your device.
Can I send the compressed file directly to WhatsApp?
Yes — after compression, click "WhatsApp" in the Send-it row. It opens WhatsApp Web with the file in your clipboard, ready to paste into a chat.
