What VidSizer is about
Who it is for
Gamers, creators, and professionals who need to share videos on platforms with strict attachment limits like Discord, WhatsApp, or email.
The problem
Video limits on Discord (20 MB) or WhatsApp (16 MB) reject files. Standard compressors use arbitrary quality settings, forcing endless trial and error.
Job to be done
When I need to send a large video, I want to shrink it below a platform's upload limit without trial and error so I can share it instantly.
How it solves it
VidSizer calculates exact bitrates, scales dynamically, and re-encodes locally so videos stay under size limits without sacrificing privacy.
What makes it different
The only target-size video compressor that runs 100% in-browser using WebAssembly — zero server uploads, 100% private.
