PostFit: Social Post Designer

Create one design, then prepare it for every place you post.

PostFit is a social post design and publishing companion for turning text into polished, multi-page graphics. Build your master design once, check it in channel-specific formats, and fine-tune each version without changing the original.

MAIN FEATURES

• Create text-based social graphics
• Adjust type size, weight, color, alignment, vertical position, and padding
• Use a solid color or a photo from your library as the background
• Start with seven styles: Minimal, Business, Bold, Dark, Korean Cute, Pop, and Quote
• Add, duplicate, delete, reorder, and review multiple pages
• Check sizes for Instagram, X, Threads, TikTok, and Pinterest
• Fine-tune text scale, position, padding, and alignment for each destination
• Automatically fit and wrap longer text within the canvas
• Render every page in a project
• Save generated graphics to your photo library
• Draft a master caption and hashtags, with optional versions for each destination
• Send images through supported sharing flows
• Mark posts complete, restore them to not posted, and view posting dates
• Autosave projects locally, rename them, or delete them
• Light and dark appearance options
• English and Japanese interface

FORMAT ONCE, ADJUST WHERE NEEDED

PostFit includes portrait feed, square, story, landscape, vertical, and pin-oriented canvas formats. Instead of simply stretching one image, it recalculates text layout and spacing for each aspect ratio. Destination-specific adjustments are stored separately, so your master design stays intact.

MADE FOR

• Creators publishing the same topic across several social channels
• Small businesses preparing announcements and educational posts
• Writers turning tips, quotes, and ideas into visual content
• Anyone building carousel-style, multi-page posts
• People who want a clear view of what has and has not been posted

SIMPLE, FOCUSED WORKFLOW

There is no account to create and no subscription. Move from writing and styling to checking, saving, sharing, and tracking in one project. Posting remains under your control, and PostFit asks you to confirm completion after a handoff when needed.

PRIVACY

Projects are saved on your device. Text, project data, and background photos are not uploaded to an external server for image generation. Permission to add to your photo library is requested only when you choose to save generated images.
