horizontal stretch · source at wave line · full zone · no mask
Select a row of pixels. Define where the stretch applies. Mask what to protect. Preview everything in real time. Export at full resolution. No Photoshop. No generative AI. Just your eye.
Each pane loops a live stretch: a single row or column is sampled from the photo, then repeated across the zone. The pink line tracks where the effect has reached.

Pixel stretching takes a single row or column from your image and repeats it across a region. Skies become smooth gradients. Water becomes glass. Light streaks become infinite. The technique has been a Photoshop manual workflow for years — this tool makes it interactive.
Every creative decision — which strip, what to protect, where the boundaries sit — is yours. The compositing pipeline itself is deterministic: same inputs, same output, every time. An optional object detector (COCO-SSD, runs locally in the browser) can suggest regions to protect, but never touches the mask without your click.
Drag a pink line to choose which row or column of pixels becomes the DNA for the entire stretch. This single decision controls the color palette and mood.
Two blue boundary lines define where the stretch applies. Everything outside stays original. Stretch just the sky, just the water, or the whole frame.
Brush with edge snap, rectangle, and ellipse tools. Paint protection directly on the canvas with live or original view. Full undo/redo history up to 40 states.
The brush compares pixel colors to stop at natural boundaries. Mask along a silhouette without pixel-hunting. Adjustable tolerance from strict to loose.
COCO-SSD runs locally in the browser to suggest bounding boxes around people, vehicles, animals, and everyday objects. Pick which ones to protect, then apply to the mask with one click.
Mask feather blurs a copy at render time — your painted mask stays crisp. Toggle stretch preview while masking for instant A/B. Reset all without reloading.
The canvas preview runs at display resolution for speed. Export renders at the original image dimensions with your exact mask, zone, and stretch settings.
All made with this tool. Different images, different decisions, different results.
Pixel stretching amplifies what the image already wants to do. Horizontal water becomes smoother. Vertical architecture becomes taller. Sky gradients become infinite. It works when you lean into the image's natural motion.
