What this tool actually does

Split mode choices are vertical slices, horizontal slices, or grid (selected by default). Column and row fields both default to 3. Effective column and row counts are constrained to 1..20; vertical mode fixes rows to 1, horizontal mode fixes columns to 1, and grid uses both fields.

Checkable behavior

Each tile samples a source rectangle at column*width/columns and row*height/rows, with source size width/columns by height/rows. Its output canvas rounds those fractional dimensions to whole pixels. Tiles are emitted in row-major order: left to right across the first row, then subsequent rows.

Controls, output and limitations

Verified example: a 12 by 6 px source in the default 3 by 3 grid creates nine 4 by 2 px tiles. Vertical mode with 3 columns creates three 4 by 6 tiles; horizontal mode with 3 rows creates three 12 by 2 tiles. Non-divisible dimensions can be resampled at fractional boundaries.

Every result is encoded as PNG and named split-1.png, split-2.png and so on. The Download results button starts each file separately at 160 ms intervals; the browser may ask for permission for multiple downloads. There is no ZIP archive, custom filename, overlap, bleed or drag-to-position cutting guide.

Load one image, choose mode and counts, press Generate, inspect tile order and boundary content, then download. Press Generate after changing settings. Processing is browser-local; keep the original and avoid assuming that recombining lossy source content or rounded fractional tiles is pixel-identical.

Active column and row counts must be whole numbers from 1 to 20. One run produces at most 300 tiles: 15 × 20 is allowed; 20 × 20 is not. All tiles from one image have the same output dimensions. The original width and height are divided by the used column and row counts, then rounded to whole pixels with a minimum of 1 pixel per axis. Fractional source boundaries may be resampled, and the combined dimensions may differ from the original. Clear removes the image and results while retaining mode and counts.

How to use

Choose one image file. Select Split mode; grid is the default and both counts start at 3. Set Columns and Vertical rows for the active axes. Click Generate image, inspect the tiles from left to right across each row, then click Download results. Downloads are separate PNG files; the browser may request permission for multiple downloads. Use Clear to remove the image and results while retaining the settings. Vertical slices use only the column count, horizontal slices only the row count, and grid uses both.

After changing the settings, click Generate image again.
