Cut a tall image into horizontal parts

Marketplace listing forms and email clients both fall over on a single very tall image — one caps the file height, the other refuses to render past a few thousand pixels. Splitting horizontally keeps the design intact while giving every platform pieces it will accept.

Two modes, and they fail differently. Count mode divides the height evenly and always covers the whole image. Height mode targets a slice height, which is what you want when the platform states a limit — but the tool caps output at 50 slices, so a very tall image with a small target quietly comes back with fewer, taller pieces than you asked for.

three steps

How to split a long image

01

Upload

A tall JPG, PNG or WebP. Full resolution is fine — nothing is uploaded, so there is no size limit beyond the memory of your device.

02

Choose the mode

Equal parts when you just need it broken up, target height when a platform states a pixel limit. Check the slice count that comes back before exporting, in case the 50-slice cap changed your answer.

03

Download

Save slices one at a time, or take the whole set as a ZIP. They are numbered in order, so uploading them in filename order rebuilds the original from top to bottom.

quick answers

Long Image Split FAQ

How many slices can I create?

Fifty at most. In height mode the requested count is clamped to that ceiling, so if you ask for 800 px slices out of a 60000 px image you get 50 slices of 1200 px instead. The slice count shown after generating is the real answer.

Are the slices exactly equal in height?

In count mode they differ by at most one pixel. The remainder is spread one pixel at a time across the first few slices rather than dumped on the last one, so nothing is cropped and nothing overlaps.

Will there be a visible seam when they are stacked?

No. The cuts are on exact pixel boundaries with no gap and no overlap, so a viewer stacking them in order sees the original image back. Seams come from the platform adding margins between images, not from the split.

Should I split before or after compressing?

Split first, then compress each slice. Compressing a 60000 px tall image and then cutting it means every slice carries artifacts that were tuned for a picture nobody will ever see whole.

What is the difference from the image splitter?

This one cuts horizontally into a strip of sections for long detail pages. The image splitter cuts a grid, which is what an Instagram carousel or a tiled banner needs.

What format are the slices?

PNG, so no compression loss is added at the cut. Run them through compress image afterwards if the listing has a file size limit.

Are files uploaded?

No. Splitting runs in your browser and the ZIP is built there too.

Is this free?

Yes — free with no watermark.
