Instagram Reels Subtitle Editor — Branded Captions for Every Reel
69% of Instagram Reels are watched without sound. CutSnap adds polished, on-brand captions to every Reel — positioned to avoid Instagram's UI, styled to match your feed aesthetic, and exported at maximum quality.

Pro Tips
Instagram Caption Best Practices
Stay within Instagram's safe zone
Instagram overlays UI at the top (profile info) and bottom (action buttons). Keep captions between 15% and 80% of the frame height to avoid overlap.
Match your brand palette exactly
Instagram audiences are visual. Consistent caption colours across all your Reels build brand recognition. Save your palette as a Style Profile in CutSnap.
Export at 1080×1920 to minimise re-encode loss
Instagram re-encodes all uploads. Start from the highest resolution CutSnap supports to retain maximum quality after compression.
FAQ
Does Instagram support external SRT caption files for Reels?
No. Instagram Reels does not support separate SRT/VTT tracks for creator uploads. Burned-in captions from CutSnap are the only way to guarantee captions appear on every device.
Can I use CutSnap for Instagram Stories as well?
Yes. Stories use the same 9:16 vertical format. The workflow is identical — upload, caption, export.
Will my branded caption fonts survive Instagram's re-encoding?
Yes. CutSnap burns fonts into the video pixels before export. Instagram's re-encoder compresses the pixels but the text remains sharp at standard display sizes.
