Slice a photo into a grid

cut locally · nothing uploaded

about this tool

The split.tools image splitter cuts one picture into perfectly aligned tiles — a 3×3 grid for your Instagram profile, a 1×3 strip for a seamless carousel, a 2×2 quad for LinkedIn, or any custom layout up to 12×12 for sprite sheets and icon packs.

Cut positions are computed from the image's true pixel dimensions, so a 3240×3240 photo yields nine exact 1080×1080 tiles with nothing lost to rounding. Tiles export as PNG (with transparency preserved) or JPEG, numbered in posting order, and bundled into a single ZIP.

Unlike upload-based grid makers, everything happens in your browser: full-resolution exports, no compression surprises, no watermarks, and no copy of your photo on anyone's server.

  2. 2 cm

    Choose the grid

    Pick a preset (3×3, 2×3, 2×2, 1×3) or set custom rows and columns. Dashed cut lines preview exactly where the image will be divided.

    Split and download

    Press Split, preview every tile, then download tiles individually or grab the whole set as one ZIP, numbered in order.

frequently asked questions

What size should my image be for an Instagram 3×3 grid?

Use a square image of at least 3240×3240 pixels. Each tile then comes out at 1080×1080 — Instagram's full display resolution. Smaller sources work too; tiles are simply smaller.

In what order do I post the tiles to Instagram?

In reverse: post tile 9 (bottom-right) first and tile 1 (top-left) last, because Instagram's profile grid fills newest-first from the top. The exported files are numbered so you can walk backwards through them.

Is the image uploaded to your servers?

No. The image is opened, previewed, and sliced entirely in your browser using the canvas API. You can verify this in your browser's network inspector, or use the tool offline.

Should I export PNG or JPEG?

PNG is lossless and keeps transparency — best for graphics, screenshots, and sprite sheets. JPEG produces smaller files for photos. For Instagram either works; the platform re-compresses uploads anyway.

Can I split images with transparent backgrounds?

Yes. Choose PNG as the export format and the alpha channel is preserved in every tile — useful for cutting icon sets and UI sprites.

Is there a file size or usage limit?

No accounts, no quotas, no watermarks. Because processing is local, the practical limit is your device's memory — far beyond any normal photo.
