Fit for Instagram

Photoshop Automation

Download

Easily prepare your images for Instagram with one click.
Fit for Instagram automatically expands, formats, and exports your photos to perfect 4:5 aspect ratio posts — optimized for maximum visual impact on the feed.
Whether you’re working on a single photo, multiple open documents, or an entire folder of images, the script handles it all cleanly and consistently.

Features

  • Batch or Open Image Mode — choose whether to process a folder of images or all currently open Photoshop documents.
  • Instagram-Ready 4:5 Format — automatically resizes and pads each image to fit perfectly in portrait ratio.
  • True White Background — expands your canvas cleanly, without leaving extra layers.Optional Border Control — add a uniform white border (by percentage) on all sides for a consistent aesthetic.
  • Smart Saving — automatically saves to an “Exports_IG” folder beside your originals.
  • Prefilled Filenames — appends “_IG” automatically, or enable manual filename confirmation.
  • Customizable Settings — easy to modify for export size, borders, and prompts.

How to Use

  • Download the script file (FitForInstagram.jsx) and place it in:
  • Photoshop > Presets > Scripts
  • Start (or restart) Photoshop to load it.
  • Go to File → Scripts → Fit for Instagram to run.
  • You’ll be prompted to:
  • Choose between processing a folder or open images.
  • Optionally confirm filenames before saving (if enabled in settings).

Advanced Notes

  • The 4:5 ratio is maintained automatically — portraits expand sideways, landscapes expand vertically.
  • Exports are JPEGs, placed in a folder called Exports_IG beside the original files.
  • The script preserves metadata and color profile.
  • It will gracefully skip any unreadable or non-image files in a folder.
  • If processing raw files, open in Photoshop and then run the script over the open image(s). Folder process will fail on raw’s.
