What size limit does Instagram enforce?
Instagram caps Feed videos at 4 GB but practically re-compresses anything over 100 MB heavily, killing quality. Reels: 4 GB cap, but 100 MB is the safe ceiling. We target 80 MB for max upload quality.

80 MB H.264 is Instagram's quality sweet spot — high enough that Instagram's encoder doesn't crush quality, low enough to upload fast on mobile data. Cloud-rendered H.265 / AV1 squeezes any MP4, MOV, or WebM down to your exact size target with no watermark — no Handbrake, no install, no popup ads.

Some, yes — Instagram always passes uploads through its own encoder. But starting from a high-quality 80 MB file gives you much better final quality than starting from a 1 GB file Instagram aggressively crushes.
9:16 for Reels, 4:5 for Feed posts, 1:1 for grid. The compressor preserves your input aspect ratio — crop or pad before uploading.
H.264 — Instagram prefers it over H.265 because of broader iOS device compatibility. The compressor defaults to H.264 for the Instagram preset.
