How to split a long image into sections
Long scroll-style product images — the ones with five features stacked vertically — don't fit any single image slot. Splitting them by hand in an editor is fiddly and easy to get wrong by a few pixels.
Set a segment width, turn on auto-split, and export. The editor cuts the image into equal vertical strips at that width, so seams line up when the buyer swipes from one image to the next.
Step by step
- Drop the long imageA 2000 × 8000 infographic is fine; there's no need to crop it first.
- Set the segment widthThis is the width each section should end up at — 1000 px for a typical A+ module. The editor scales to that width and cuts top to bottom.
- Preview the seamsCheck the cut points before exporting. Text that straddles a seam is the one thing auto-splitting can't fix for you.
- Export in orderSections are numbered sequentially so they upload to a carousel in the right order.
Keep the split sections consistent: if section 1 is 1000 × 1000, make them all that size, because marketplaces display carousel images at one fixed ratio.
Why not just use something else
- Manual cropping in Photoshop — One slice per section, and if you're off by 3 px the seam shows when the images sit next to each other.
- Generic splitters — Most only cut at fixed pixel heights, not at a target width, and don't handle a batch.
- This editor — Splits at export time as part of the same batch you're already resizing.

FAQ
What is splitting a long image used for?
Amazon A+ content modules, Etsy and Shopify carousels, and anywhere a marketplace accepts several images but not one very tall one.
Do the sections need to be the same height?
They should be the same width and ideally the same ratio, because the gallery displays them in one frame.
Can I split several long images at once?
Yes — it's a batch operation, same as resizing. Set the width once and the whole folder is cut.
Does splitting reduce quality?
No. Each section is copied from the original pixels at the target width, so there's no repeated re-compression.
