As answered by people managing GRID34SYNC and Split an Image.
GRID34SYNC's answer
Most Instagram planners still show the old square grid — Grid34Sync previews your profile in the real 4:5 portrait format Instagram now uses, so what you see is exactly what followers see. It also combines three tools in one: a drag-and-drop feed planner, a 9-grid puzzle maker (split one photo into 9 seamless tiles), and a carousel maker (split a wide photo into 2–3 slides). Everything runs in the browser — no app download, no account, free for preview.
Split an Image's answer:
Split Image is a user-friendly tool that allows you to quickly and easily convert any image into different format.
GRID34SYNC's answer
Grid34Sync is built for Instagram creators and small business owners who care about how their profile looks as a whole — not just individual posts.
This includes: - Content creators and influencers planning a cohesive aesthetic grid - Small businesses using Instagram as their storefront - Social media managers who need to visualize feed layout before publishing - Anyone experimenting with 9-grid puzzle feeds or panoramic carousels
Typically users who find Grid34Sync frustrating with subscription-based tools like Planoly or Later, and want a fast, no-login alternative that runs entirely in the browser.
Split an Image's answer:
Whether you need to resize an image for social media, create a thumbnail for a blog post, or simply want to make a square version of a rectangular image, this tool has got you covered.
GRID34SYNC's answer
Honestly? I'm not a developer. Grid34Sync was built entirely with the help of AI — Claude and Codex handled the code, I handled the product vision and quality control.
The actual stack underneath: Next.js 15, TypeScript, Cloudflare Workers, Tailwind CSS. But the real technology is: a non-technical founder stubborn enough to ship anyway.
Split an Image's answer:
nextjs+tailwind,that's all!
GRID34SYNC's answer
Grid34Sync is in early stage — our current users are individual Instagram creators and small business owners who discovered the tool through word of mouth. No enterprise clients yet.

GRID34SYNC's answer
Grid34Sync was born out of frustration.
I wanted to plan my Instagram feed, but every tool I tried was either expensive, bloated with features I didn't need, or forced me to finish arranging photos before I could see how they actually looked togeher.I'd spend an hour planning, render the preview, hate it, and start over.
I just wanted something simple: drag photos, see the grid update in real time, done.
So I built it. What started as a personal WYSIWYG feed planner grew into a full toolkit — puzzle feeds, carousel splitting, a blank tile generator that pulls colors directly from your photos so your grid stays harmonious without hunting for matching images online.
The last piece was accuracy. Most tools still preview Instagram grids as squares. But Instagram updated its display to a 4:5 portrait format in 2025 — so we built around that from the start. What you see in Grid34Sync is what your followers actually see.
No tutorials needed. No subscription required to get started. Built by someone who hates reading manuals, for everyone else who does too.

Split Image is a user-friendly tool that allows you to quickly and easily convert any image into different format, make for everyone, free online!
Upload an image and split it by fixed ratio, pixels, shapes, or split the image into 2/3/4/5 equal parts/sections. Processing happens fully in your browser.
GRID34SYNC's answer
Most Instagram planning tools (Planoly, Later, Preview) require an account just to get started. Grid34Sync lets you plan, rearrange, and preview your feed instantly — no sign-up required.
Unlike single-purpose grid splitters, it combines feed planning, 9-grid puzzle creation, and carousel splitting in one place. It also uses Instagram's actual 4:5 portrait display format, so you see exactly what your followers see. Pro plan ($9.9 one-time) unlocks watermark-free exports and Instagram direct publishing.
