How to split image files online

To split an image online, drop it on the split image tool above, set the rows and columns (or a tile size in pixels), check the cut lines on the preview, and press Download all. Each piece is saved as its own file, named by row and column, inside one ZIP. The image is cut in your browser, so nothing is uploaded and there is no watermark.

This image splitter works on one picture at a time and makes up to 100 tiles, from a 1 × 2 cut down the middle to a 10 × 10 grid. The split image preview draws every cut line and a number on each tile, so you can see whether a cut runs through a face before saving anything.

Split image into parts: rows and columns, or a tile size

There are two ways to tell the split image tool where to cut. Rows × columns asks how many pieces you want: 3 columns and 2 rows gives six parts, whatever the image measures. Tile size asks how big each piece should be in pixels, for example 1080 × 1080, and the image splitter works out how many fit. Use the first when the number of pieces matters, and the second when the pixel size does.

A PNG source is split into PNG tiles, which suits screenshots and anything with transparency. Every other format, including HEIC from an iPhone, AVIF and WebP, is saved as JPG at 92% quality, which is close to the original for a photo and opens anywhere. The files are named after the source with the row and column added: photo-r1c1.jpg is the top-left tile, photo-r1c2.jpg the one to its right, and photo-r2c1.jpg the first tile of the second row. The names sort in reading order in any file manager.

Need fewer files? Each tile has its own download button, so you can split image grids and keep only the pieces you want.

Equal tiles or exact pixels

Most pictures do not divide evenly, and every split image tool has to decide what happens to the remainder. A 1,000-pixel-wide picture cut into 3 columns is 333.33 pixels per column, and a pixel cannot be cut in three. This one gives you the choice:

What Equal and Exact do with an uneven split

Source width	Columns	Equal	Exact
1,000 px	3	333 × 3 (1 px trimmed)	one of 334, two of 333
4,000 px	3	1,333 × 3 (1 px trimmed)	one of 1,334, two of 1,333
1,920 px	7	274 × 7 (2 px trimmed)	two of 275, five of 274
3,240 px	3	1,080 × 3 (nothing trimmed)	1,080 × 3 (same result)
999 px	10	99 × 10 (9 px trimmed)	nine of 100, one of 99

Arithmetic of this tool. Equal trims at most columns − 1 pixels across and rows − 1 pixels down.

Equal makes every tile exactly the same size and drops the leftover pixels at the edge — never more than one pixel less than the number of columns, so 9 pixels at most on a 10-column cut. Choose it when the pieces must match, such as icons or game tiles. Exact keeps every pixel and spreads the remainder, so some tiles are one pixel wider or taller than others. Choose it for printing, where losing an edge matters more. When the size divides evenly, both give the same result.

Split image for printing: a poster across A4 or Letter sheets

A home printer cannot print a poster, but it can print four or nine sheets that tape together into one. Split image tiles in a 2 × 2 or 3 × 3 grid, print each tile on its own sheet, trim, and join. The numbers below are worth getting right first, because every sheet has an edge the printer cannot reach.

An A4 sheet is 210 × 297 mm and US Letter is 8.5 × 11 inches (216 × 279 mm). Printers leave a margin: the HP Officejet 6300, as one example, needs at least 3 mm at the top and bottom and 7.1 mm at each side on both sizes. That leaves a printable area of about 195.8 × 291 mm on A4 and 201.7 × 273.4 mm on Letter. Your printer's figures may differ slightly; they are in its user guide under margins.

Poster sizes from tiled sheets, and the source pixels each one needs

Layout	Sheets	Finished print area	Source at 150 ppi	Source at 300 ppi
2 × 2 A4 portrait	4	392 × 582 mm (close to A2)	2,313 × 3,437 px	4,625 × 6,874 px
3 × 3 A4 portrait	9	587 × 873 mm (close to A1)	3,469 × 5,156 px	6,938 × 10,311 px
2 × 2 Letter portrait	4	15.9 × 21.5 in	2,382 × 3,229 px	4,765 × 6,458 px
3 × 3 Letter portrait	9	23.8 × 32.3 in	3,573 × 4,844 px	7,147 × 9,687 px

Calculated from the printable area above. Paper sizes: Markus Kuhn, University of Cambridge, on ISO 216 paper sizes. Margins: HP Officejet 6300 user guide, print margin specifications. Both checked November 3, 2026.

For scale: a 3,000 × 4,000 pixel (12-megapixel) photo printed as a 2 × 2 A4 poster comes out at about 175 pixels per inch; as a 3 × 3 poster, about 116 ppi, which looks soft up close. A-series sheets also scale neatly: because every A size has the same √2 shape, four A4 sheets make an A2 and sixteen make an A0.

Crop to the poster's shape first. A 2 × 2 A4 poster is 0.673 as wide as it is tall; Letter is 0.738. Crop the source to that shape so each tile fills its sheet.
Choose Exact. For print, keeping the edge pixels matters more than identical tiles.
Print every tile at the same scale. Use the same "fit to printable area" setting for all sheets, with no auto-rotate.
Trim one margin on each join. Cut the white edge off the right side and bottom of the sheets that overlap a neighbour, then butt the edges together.
Tape from the back. Join the top row, then the bottom row, then the two rows.

The tool does not add overlap or cut marks; the trim-and-butt method above is how you join its tiles cleanly.

Which setting to use for each job

People split image files for very different reasons, and the right grid follows from the reason:

Common reasons to split an image, and the settings to use

Job	Split	Tiles	Notes
Poster on home paper	2 × 2 or 3 × 3	Exact	Crop to the sheet shape first; see the table above.
Instagram profile puzzle	Insta grid mode, 3 × 1 to 3 × 4	Fixed 1080 × 1440	See the Instagram grid maker for posting order.
Wide photo as a swipe post	Carousel mode, 2–10 slides	Fixed per ratio	Uses 4:5, 3:4 or 1:1 slides.
A long screenshot for a chat app	Rows only, e.g. 3 × 1	Exact	Each part stays readable instead of being shrunk.
Game map or texture tiles	Tile size, e.g. 256 × 256	Equal	Identical tiles line up again in a grid.
Worksheet or puzzle pieces	2 × 2 to 4 × 4	Either	Number the pieces from the file names.

Modes and limits of this tool: up to 10 rows and 10 columns, 100 tiles at most.

Switch between Grid, Insta grid and Carousel at the top of the tool without loading the image again.

Other ways to cut an image into pieces

If you already have the software, you may not need a split image tool at all. Adobe Acrobat and the free Acrobat Reader have a Poster option in the Print dialog that tiles one page across several sheets, with a tile scale, an overlap and cut marks — the overlap is the one thing this tool does not do. Put the image into a PDF first (our Images to PDF tool does that), then print it as a poster. You get paper, not image files.

ImageMagick, the free command-line tool, splits into equal tiles with the @ flag: magick photo.jpg -crop 3x2@ +repage tile_%d.jpg cuts a 3 × 2 grid. It is ideal for hundreds of images at once, but tiles are numbered from zero rather than by row and column, and HEIC needs a build with the right delegate.

Split image — questions

How many pieces can I split an image into?

Up to 10 rows and 10 columns, so 100 tiles at most. With Tile size, the number of tiles follows from the image size and the tile width and height, and the same limit of 100 applies.

Will splitting an image reduce its quality?

Not for PNG sources, which are split into PNG tiles without loss. Other formats are saved as JPG at 92% quality, which is visually very close to the original. The pixels are not resized: each tile is a piece of the original at full resolution.

What is the difference between Equal and Exact?

Equal makes every tile the same size and trims up to columns − 1 pixels across and rows − 1 pixels down. Exact keeps every pixel and spreads the remainder, so tiles can differ by 1 pixel.

Can I split image files on iPhone or Android?

Yes. The tool runs in current mobile browsers and accepts HEIC photos from an iPhone. Download the ZIP, save single tiles, or use Save to Photos to put the tiles in your photo library through the share sheet.

How do I split image tiles for printing on A4?

Crop the image to the shape of the finished poster, split it 2 × 2 or 3 × 3 with Exact tiles, print each tile at the same scale, trim the white margin on the edges that join, and tape the sheets from the back. The table on this page lists the pixel sizes for 150 and 300 ppi.

Is my image uploaded?

No. The image is decoded, cut and saved in your browser. Anonymous interface events, such as the grid size, are counted for analytics; the image and its file name never leave your device.

Can I split an image into a grid for Instagram?

Yes. Switch the mode to Insta grid for 1080 × 1440 tiles numbered in posting order, or to Carousel for swipeable slides. The Instagram grid maker page explains the posting order.
