Platform scenarios
Most rejected uploads are limit problems, not codec problems. Choosing the destination first tells the video size reducer what size budget to work backwards from.
- Discord 10MBNormal free uploads on Discord are capped around 10MB, which a modern phone blows past in seconds of recording. The video size reducer's Discord preset is usually the fastest fix — no upload boost, no external link.
- WhatsApp, Reels, TikTok, Shorts, and X - These platforms re-encode whatever you upload anyway. Handing them the video size reducer's smaller, already-optimized output makes final quality more predictable and the upload faster.
