Drop a banner into the splitter above and it cuts equal vertical panels, three to start with and up to 20. Drag the seams to move them, switch the axis for horizontal strips instead, then download the panels numbered left to right. Nothing is uploaded.

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.

A banner is a wide image designed to be seen in one piece, which is a problem the moment the place you want to put it only accepts small square uploads. Splitting is the workaround: cut the banner into panels, upload them separately, and let the layout put the picture back together.
Where that works depends on the destination. A profile grid three squares wide takes a banner cut into three panels across the top row. A carousel takes a banner cut into slides. Twitch panels are rendered 320 pixels wide, so a wide strip cut into equal panels stacks under a channel at a predictable size. Anywhere with a fixed grid and separate uploads is a candidate.
The count runs from 2 to 20 and the seams are draggable, which matters for banners more than for photos. Banner artwork usually has a logo, a headline and a call to action sitting at specific points, and an even split will cut straight through at least one of them. Move a seam into the empty space between elements instead.
The axis toggle turns vertical panels into horizontal strips, for the cases where a tall banner needs breaking up rather than a wide one.
Panels are numbered left to right. Everything is cut on a canvas in this page, at full source resolution, with no watermark and nothing uploaded.
A banner cut into three panels fills the top row of a three-column profile grid. Post the right-hand panel first and the left-hand one last, because the newest post lands on the left of the row. Check the preview before uploading, since reversing the order is very visible.
Twitch panels render 320 pixels wide, so a wide strip cut into equal panels stacks under a channel at a consistent size. Cut the strip into as many panels as you have links or sections, and keep each panel's text large enough to read at panel width rather than at design width.
Cutting a banner into slides turns a wide design into a post people swipe through. Pad each panel to 4:5 so all the slides share an aspect ratio, otherwise the platform crops the ones that do not match the first. Post the leftmost panel first.
A wide banner shrunk onto a slide is unreadable. Cut it into panels and reveal one per slide, and the type stays at a workable size. Export as PNG so the edges of logos and lettering stay clean rather than picking up compression artefacts.
Drop the banner into the splitter above and set the number of panels, from 2 to 20. Equal vertical panels appear in the preview immediately. Drag any seam to move it, pick an output format, then download the panels one at a time or all together as a ZIP.
Cut it into three panels, since profile grids are three columns wide, then post the right-hand panel first and the left-hand one last. The newest post takes the leftmost position in a row, so uploading in reading order puts the banner on backwards.
It depends where the panels are going. Twitch renders panels 320 pixels wide, so design above that and let it scale down. For a carousel, pad each panel to 1080 × 1350 px. For a profile grid, square tiles at 1080 × 1080 px match the grid layout.
Yes. Export to PNG or lossless WebP and every panel is an exact copy of its part of the banner, at full source resolution. That matters more for banners than photographs, because banner artwork is usually type and flat colour, which JPG compression handles badly.
Yes. The axis toggle switches the cut from vertical to horizontal, so instead of side-by-side panels you get stacked strips. Everything else works the same: the count goes up to 20, the cut lines are draggable, and the strips are numbered from the top.
Up to 20 in a single row. In practice three to six is where most banners land, because past that each panel gets narrow enough that whatever is on it stops being readable at the size the destination displays it.
