Wideswipe cuts one wide photo into 2 to 20 tall strips. Post them together on X and they show up as one big photo you swipe across, instead of a small letterboxed 16:9 image. Free, no account. Everything runs in the browser; photos never leave the device.
How X shows several images
A post with several images is a sideways carousel on X. Since 12 November 2026 a post can hold up to 20 photos. Every image becomes a tall card with rounded corners and a 6 px gap between cards. The taller the cards, the bigger the photo in the feed, but fewer cards fit on screen at once.
Strips and sizes
The Strips slider sets the count, from 2 to 20. Its label shows how many strips fit on screen at once, for example "8 · 5.0 on screen". Dots on the slider mark 4 and the count that fits your photo.
Each strip has a shape (height divided by width), from 1:2.1 to 1:48. The shape follows your crop and the count: more strips on the same photo means narrower, taller strips. Measured on X in November 2026, on an iPhone 16 Pro (feed column 322 px) and on X web (column 564 px), the feed row is never taller than about 1.25 times the column width, so a taller strip only makes it narrower.
Crop is free. Drag the corners or the edges. The frame turns red at the limits of what the strips can take.
Files are JPEGs, each at most 4096 px tall and never upscaled beyond your photo.
The gap fix
The 6 px gaps hide nothing: X just places the cards apart. If you cut a photo into equal parts, every line that crosses a gap (a horizon, a roof, a ridge) jumps sideways by the width of the gap. Wideswipe leaves out the thin slice of photo that would sit behind each gap, so lines continue straight across, at every seam. It is tuned for X on phones, where most people scroll: off by under 1 px on every iPhone, about 4 px on X web.
Getting the best result
- Use a landscape photo: 16:9 from a phone or wider. The wider the photo, the more strips suit it.
- Choose photos with something running across the whole width: a horizon, a skyline, a row of people. A single subject in the middle ends up split by a gap.
- If the photo is too wide for the count, Wideswipe trims its ends. Add strips, or use Crop to choose what stays.
- Post all strips in order. Files are named ws-01-name.jpg up to ws-20-name.jpg, zero-padded so they sort correctly. On X, select them in that order: X posts images in the order you select them.
- On a phone, Share to X sends all files to X at once. On a computer, Download saves one zip with all files. Unzip it, press Open X, then add all photos to a new post at once, in order.
- Photos above 12 MP are scaled down on the device first. X shows far less detail than that, so nothing visible is lost.
