A 1x3 split is one row and three columns: three vertical panels of equal width, each the full height of the source. Drop your image into the splitter above and the three panels appear in the preview. Drag either seam to move it, then download the panels as a ZIP.

Drag any line to move a cut. Tab to a line and use the arrow keys to nudge it one pixel, or hold shift for ten.
Vertical cuts give side-by-side pieces. Horizontal cuts stack them.
The tool picks the rows and columns that keep the pieces closest to square.
A shared strip on each seam, so the sheets can be trimmed and taped.
Each piece is resized to the size this page targets before it is saved.
Your image never leaves your device. Splitting runs in your browser with the Canvas API.

1x3 means one row and three columns. Three panels side by side, each a third of the width and the full height. If you wanted three stacked strips instead, that is 3x1, three rows and one column, and it is the arrangement people mix this up with most often.
The convention is rows first, columns second, everywhere on this site. Read 1x3 as "one row, three columns" and the shape follows.
What you get depends entirely on the source. A 3000 × 1000 panorama gives three 1000 × 1000 px panels, close to square. A 1080 × 1350 portrait gives three 360 × 1350 px panels, narrow and tall. The panels are always the full height, which is what makes this arrangement work for triptychs and carousels and not much good for anything that needs to be read top to bottom.
Both seams are draggable, and this is worth doing before you export rather than after. Three equal thirds put two vertical lines through the middle of the frame, which is exactly where a face or a subject tends to sit. Move a seam ten percent either way and the panels usually improve.
The split runs on a canvas inside the page. Your image is read, cut and handed back without ever going to a server.
Three panels of one photograph, hung with a gap between them, is the classic triptych. A 1x3 cut gives all three the same width so the frames match. Keep the horizon or the main line of the composition running across the seams, and avoid putting a face right where a cut lands.
Three panels swiped in order read as one wide picture. Pad each panel to 4:5 first so all three slides share an aspect ratio, which the platform requires before it starts cropping to match the first slide. Upload the left panel first so the picture reads in the right direction.
Three tiles across the top of a profile makes a banner. Cut 1x3, then post the right-hand panel first and the left-hand one last, because feeds fill from the top left with the newest post. Check the preview before uploading: reversing the order is a common and very visible mistake.
Comic strips, before-and-after-and-after sequences and three-column layouts often arrive as a single flat file. A 1x3 cut recovers each panel. Drag the seams into the gutters between panels rather than accepting even thirds, since laid-out artwork rarely divides at exact fractions.
One row and three columns. You get three vertical panels side by side, each one third of the source width and the full source height. The reverse arrangement, 3x1, is three rows and one column, which gives three horizontal strips stacked on top of each other.
The order is rows then columns. 1x3 gives three tall panels arranged left to right. 3x1 gives three wide strips arranged top to bottom. Both produce three files from the same source, but they cut along opposite axes and are not interchangeable.
One third of the source width, at full source height. A 3000 × 1000 image gives three 1000 × 1000 px panels. When the width does not divide by three, the first two panels round down and the last one takes the leftover pixel, so nothing is lost.
Yes, in two ways. As a carousel, pad each panel to 1080 × 1350 px so the three slides share one aspect ratio and swipe together. As a profile row, post the panels right to left so the newest post lands on the left of the row.
Both seams are draggable, and the panels either side resize as you move them. That lets you push a cut out of a subject's face or line it up with a gutter in laid-out artwork. Reset to equal restores exact thirds whenever you want to start again.
Yes. No scaling happens at any point. Each panel holds the pixels that were in its third of the source file, at the resolution they were captured. Export to PNG or lossless WebP to copy them exactly, or to JPG at quality 92 for smaller files.
