Why files bounce on WhatsApp
If you share an iPhone 4K 60fps video via WhatsApp's media gallery, WhatsApp recompresses it from 50 Mbps down to ~2 Mbps, stripping HDR10, Rec.2020 color, and 60fps smoothness.
How to send files larger than 2 GB (Documents) / 16 MB (Media)
- Upload your raw 4K video or photo archive to LimeShare in your mobile browser.
- Copy the sealed link and send it directly in your WhatsApp chat.
- The recipient downloads the bit-for-bit pristine file without any WhatsApp re-compression or phone number leakage.
Frequently asked questions
Why does WhatsApp compress my 4K video to low quality?
WhatsApp optimizes for data bandwidth and chat speed on mobile networks. It downsamples media sent through the photo gallery. Sending via LimeShare preserves 100% original quality.
Can I send files over 2 GB to WhatsApp contacts?
Yes. LimeShare supports files up to 3 GB free (and 50 GB on Pro), generating a link you can paste into any WhatsApp conversation.
