PNG, JPEG, static WebP or BMP. 40 MiB/file, 24 MP, 8192 px/side; pixel operations 6 MP. GIF: 120 frames and 24 MP across all frames. Split: at most 256 pieces.
Checkerboard areas indicate transparency. Previews fit the screen; downloads keep the displayed pixel dimensions.
Details
Image exports re-encode pixels; Base64 encode/decode preserves original bytes. BMP 1/4/8/16-bit and GIF reduce colors. BMP 4/8-bit palettes use up to 8/128 colors. JPEG fills transparency.
IMAGE WORKSPACE
Understand the task
Image splitting partitions a source rectangle into smaller raster images. Grid mode divides each axis at integer coordinates so every source pixel belongs to exactly one piece. Fixed-size tiles retain a smaller final row or column when the dimensions do not divide evenly.

How to use
- Choose the operation that matches your task. Import a file, try the example, or enter text for generation and Base64 decoding.
- Adjust the visible settings and create a preview. The original remains available. Changing settings disables the old download until you run again.
- Inspect the result, details and dimensions. Copy text when available or download the file. Use the alternate download for PNG, extracted frames or a second representation.
Limits and common errors
The ZIP contains numbered files and a manifest with source coordinates and dimensions. No gutter or overlap is inserted. Transparent edges remain transparent in PNG/WebP; JPEG fills them with the selected background. Grid counts cannot create empty tiles.
