Why Use This Instagram Carousel Maker?
2 or 3-Tile Auto Split
Upload one photo and the Instagram carousel maker instantly slices it into 2 or 3 perfectly equal tiles. Choose your Instagram carousel format — the edges align seamlessly so viewers see one continuous image as they swipe.
Lossless 1080 px Export
Every tile exports at 1080×1080 px — the native Instagram square resolution. Your carousel slides stay sharp and pixel-perfect on any screen, from mobile preview to desktop profile.
Instant Tile Download
Tiles download individually, numbered in sequence (Tile_01, Tile_02…). Upload them to Instagram in order and your carousel slides reveal the full panoramic image as followers swipe left.

Smart Fill — Not a Black Letterbox
Most tools crop your photo to a square and pad with black bars. Grid34Sync automatically extends the background with a blurred version of your image — every tile looks polished, not squeezed.
Instagram Carousel Size — 2026 Guide
Getting the Instagram carousel size right is the difference between a sharp, full-screen post and one that looks cropped or blurry. Here are the three numbers every creator needs to know.
Standard carousel size
The recommended Instagram carousel size is 1080×1080 px per slide (1:1 square). This Instagram carousel maker exports every tile at exactly this resolution — upload-ready with no resizing needed.
Portrait carousel size
You can also use 1080×1350 px (4:5 portrait) for carousel slides that fill more vertical screen space in the feed. All slides in a carousel post must share the same aspect ratio.
Source image dimensions
For a seamless split carousel, start with 2160×1080 px (2 slides) or 3240×1080 px (3 slides). The Instagram carousel maker then exports each tile at the correct carousel size automatically.
Frequently Asked Questions
Everything you need to know about splitting photos into seamless Instagram carousel slides.
An Instagram tile maker is a free online tool that splits one wide photo into 2 or 3 equal tiles. You post each tile as a separate slide in an Instagram carousel post — when viewers swipe, the image continues seamlessly across slides.
Upload your photo, select the Carousel 2-tile or 3-tile mode, adjust the crop to frame your image, then click Export. Grid34Sync slices it into numbered tiles ready to upload as a multi-photo Instagram post.
The 2-tile carousel splits your photo into 2 slides (ideal for wide panoramic shots), while the 3-tile carousel splits it into 3 slides for an extra-wide image or more visual impact. Both use the same seamless splitting engine.
For best results, use a photo at least 2160×1080 px for a 2-tile carousel or 3240×1080 px for a 3-tile carousel. Each tile exports at 1080×1080 px — the native Instagram square resolution.
Yes — the carousel tile maker is 100% free with no account required. Upload, split, and download your tiles at no cost. PRO users unlock 4K HD exports and watermark-free downloads.
After downloading your tiles, open Instagram and create a new post. Tap the multi-photo icon, then select all tiles in order (tile 1 first, tile 2 second, etc.). When followers swipe left, the image flows seamlessly from one slide to the next.
Instagram's desktop web uploader defaults to a 1:1 square crop. To fix it, click the expand icon (↔) at the bottom-left of the upload preview and select “Original”.
An Instagram carousel post is a multi-image post that lets viewers swipe left to see up to 10 photos or videos in sequence. Carousels consistently earn higher engagement than single-image posts because each swipe is a second chance to be seen in the algorithm. A seamless carousel — where one wide photo splits across multiple slides — creates a cinematic reveal effect that stops the scroll.
The recommended Instagram carousel size is 1080×1080 px per slide (1:1 square). You can also use 1080×1350 px (4:5 portrait) for a taller format that takes up more screen space in the feed. For a seamless split carousel, use a source image of at least 2160×1080 px (2 slides) or 3240×1080 px (3 slides) so each exported tile is exactly 1080×1080 px at full quality.
