How to use the image splitter
- Choose one image.
- Set Rows and Columns, each from 1 to 20.
- Pick Save as: same format as the original, JPEG, PNG or WebP. For JPEG and WebP, set Quality.
- Press Split. You get every piece as a file, plus a summary such as “9 pieces of about 1000 × 1000 px”.
What it does and when to use it
The splitter cuts a picture along straight lines into a grid of same-sized tiles. Common uses:
- Grid posts: a wide photo shown across three posts in one row of a profile.
- Swipe carousels: a panorama cut into 1 row of several pieces, so it moves on as people swipe.
- Long screenshots: a tall page capture cut into readable parts.
- Big prints on small paper: a poster tiled over several A4 sheets.
- Puzzles and game tiles: a picture cut into 4 × 4 squares.
To cut out one area instead, use the image cropper. If tiles must be an exact size for a platform, crop or resize the whole picture first so it divides evenly. To put tiles back together, or combine different photos, the image collage maker does the reverse job.
How it works
The image is decoded on your device, never uploaded. Then:
- tile width = image width ÷ columns, rounded down
- tile height = image height ÷ rows, rounded down
- the last column and last row take any remaining pixels
Each tile is copied out pixel for pixel and saved in the format you chose. “Same format as the original” keeps JPEG, WebP and PNG; other formats such as GIF or BMP are saved as PNG. A tile with transparency is never saved as JPEG by that setting. File names keep your original name and add the position, such as beach-r2c3.jpg.
Worked examples
These sizes follow the rule above.
- A 3240 × 1080 panorama, 1 row × 3 columns. Three square pieces of exactly 1080 × 1080 px.
- A 3000 × 3000 photo, 3 × 3. Nine pieces of 1000 × 1000 px, from
-r1c1to-r3c3. - A 1081 × 1081 image, 3 × 3. 1081 ÷ 3 leaves 1 pixel over, so the first two columns are 360 px wide and the third is 361 px. The rows work the same way. The bottom-right piece is 361 × 361.
- A 1080 × 7000 screenshot, 4 rows × 1 column. Four strips of 1080 × 1750 px.
Limits and tips
- Rows and columns are capped at 20 each, so at most 400 pieces.
- Plan the image so important faces or text do not fall on a cut line.
- One image per run. For several pictures, split them one after another.
