One Click, Every Platform
Smart reframe your Premiere Pro sequences for TikTok, YouTube Shorts, Instagram Reels, and any aspect ratio — automatically.
What is Auto Resize?
Auto Resize intelligently reframes your horizontal footage to vertical, square, or any custom aspect ratio while keeping your subject perfectly centered.
TikTok & Shorts
9:16 vertical format optimized for TikTok, YouTube Shorts, and Snapchat.
Instagram Reels & Stories
9:16 and 4:5 formats perfectly sized for Instagram's feed and stories.
Custom Ratios
Any aspect ratio you need — 1:1 square, 4:3 classic, or fully custom dimensions.
How It Works
Three steps to repurpose your content for every platform.
Select Your Sequence
Open your horizontal (16:9) sequence in Premiere Pro. Auto Resize works with any resolution.
Choose Target Format
Pick from preset ratios (9:16, 1:1, 4:5) or enter custom dimensions. Preview the reframe in real time.
Export for Every Platform
Auto Resize creates a new sequence with smart-cropped footage. Fine-tune keyframes if needed, then export.
