What format are the sliced tiles exported in?

Tiles are exported as high-quality JPEG or PNG images matching your selected quality settings.

Is there a limit on input image resolution?

The page sets no size ceiling of its own: it paints the file onto one canvas and reads a data URL back from each tile, so what your browser can hold is what you can split. Very large photos simply mean more full-size canvases alive at once.

Are my photos uploaded to a cloud server?

No. All canvas slicing and ZIP archiving execute locally in your web browser memory.

Do the tiles overlap or leave gaps between panels?

Neither. Each panel starts exactly where the previous one ended, at column times the tile width, so the cuts touch. The only pixels that disappear are the remainder strip when the source size does not divide evenly.

Does the split wait for a button press?

No. The crop reruns as soon as the file loads and again whenever you change the preset, the custom rows or columns, the format or the quality, so the preview always shows the tiles the current settings would export.

What do the files inside the ZIP look like?

One image per tile named after its position — row and column both counting from 1 — with the extension matching the format you chose. The archive itself carries the source name plus the grid, such as cover-2x2-tiles.zip.

Free & Private Online Browser Utility

Split Image Into Grid

Split photos and artwork into clean multi-tile grid squares for Instagram profiles, carousel posts, banners, and photo collages directly in your browser. Choose standard grid layouts (3x1, 3x2, 3x3, 2x2), adjust crop alignment, and download individual tiles or a single ZIP archive. All slicing uses HTML5 Canvas in browser memory without sending high-resolution photos to external servers.

How to use

Step 1: Upload Image

Drag and drop your photo or graphic file into the upload dropzone.
Step 2: Select Grid Dimensions

Pick a preset or type your own columns and rows — the custom fields accept 1 to 8 of each, so the largest grid this page will build is 64 tiles.
Step 3: Download Sliced Tiles

Click any tile to save that one panel, or download the whole set as a single ZIP. Every file is named after its position, for example photo-row1-col2.jpg, and the archive is photo-3x1-tiles.zip.

Options explained

Instagram Grid Presets

Preset aspect ratios configured for 3-column Instagram profile layout displays.

When to use: Use to create banner grids across your social media profile feed.

Numbered Tile Sequencing

Writes each panel with its position in the name (row then column, counting from 1), so a downloaded ZIP can be uploaded in order without opening the images to work out which slice is which.

When to use: Helps you post tiles in the correct chronological sequence so the grid aligns on your profile.

ZIP Archive Packaging

Bundles all sliced tiles into an uncompressed or lightly compressed ZIP file using JSZip.

When to use: Download all sliced tiles in a single click on desktop or mobile.

Worked example

Input: High-resolution photo (3000x3000px) split into a 3x3 grid layout

Output: Nine individual image tiles (1000x1000px each) numbered sequentially in a ZIP archive

Processed via CanvasRenderingContext2D.drawImage slicing sub-regions.

Tips & limits

For a 3x3 Instagram grid, post tile 9 first and tile 1 last so the image reassembles correctly on your profile.
Using a high-resolution starting image (at least 2000px) allows each individual tile to stay sharp on mobile screens.
All slicing executes in browser RAM without uploading large image files to remote servers.
A three-column split of a 1,000-pixel-wide photo gives three 333-pixel tiles, because each tile is the whole number of pixels that fits: the leftover strip on the right edge is never drawn into any panel.
The quality slider only appears while JPG is selected. PNG tiles are written with no quality argument at all, so a 3x3 profile grid of PNGs stays pixel-identical to the source crop.

Common problems

Tiles appear in the wrong order after posting to Instagram: Instagram displays posts chronologically from bottom-to-top; upload your numbered tiles in the sequence suggested by the tool.
Image appears cropped along the top or bottom: The split always starts at the top-left pixel and this page has no crop or pan step, so off-centre subjects lose their edge to the remainder strip. Resize or crop the photo square first, then split.
Dropping or selecting a file changed nothing: Only the first chosen file is read, and anything whose type is not an image is ignored without a message. A truncated or corrupt photo also lands as an empty grid, because the loader has no error branch — reopen the picture from the app that saved it.

How to Create an Instagram Profile Grid Takeover

An Instagram grid takeover involves planning your posts as parts of a single cohesive image mosaic that looks stunning when viewed on your profile page.

Select your source photo: Use a high-resolution photo (3240 × 3240 px or higher).
Split using 3×3 preset: The tool generates 9 numbered tiles (row1-col1 through row3-col3).
Post in reverse order: Start with the bottom-right tile (row3-col3) and post leftward and upward, finishing with tile row1-col1. Because Instagram feeds display chronologically in reverse, the tiles assemble into the original image on your profile grid!
