About Batch Resize Images
Presets crop or fit to the exact size each platform expects: Instagram post 1080 × 1350, Story 1080 × 1920, YouTube thumbnail 1280 × 720. Save your own sizes as presets in this browser. "Width" and "Fit in a box" never enlarge small photos unless you allow it.
Processing happens in this browser tab: your images are never uploaded, and the result is ready as soon as you download it. Large photos take a moment longer on phones; nothing is limited by size.
