Triptych Art Split Designer
One picture. Three connected panels.
Photos stay on this device.
No upload. No sign-up.
Preparing your example…
Drag artwork in Edit composition. Arrow keys move 1 mm; Shift + arrow moves 10 mm. The wall preview is a measured flat layout, not a room photograph.
Three files. One finished set.
Check or adjust the selected panel
Use negative values to move left or up. Corrections affect this panel only and can break the connection at its edges. Compare On the wall before downloading.
Turn one composition into three real prints
- Set the finished sizes. Choose equal panels or a wider center, then enter the wall gaps and any wrap or bleed your supplier needs.
- Place your picture. Move and crop it as a single composition. Compare the three-panel wall view, and make a separate panel correction only when needed.
- Save the numbered set. The complete ZIP includes three PNGs, three actual-size PDFs, a measurement list and an installation check. Keep the left-to-right numbers with the prints.
Before you print
Do wall gaps become white borders in the files?
No. By default, adjoining source regions are split into three separate prints and gaps appear only in the wall preview. The optional gap-strip mode leaves out measured strips of the source picture, as if the gaps were windows onto the scene. Neither mode paints wall space into a panel.
Will different panel widths stretch my photo?
No. One proportional crop spans the whole composition. Panels sample their own measured region from it. Editing the combined width changes panel proportions together; editing one panel updates the total. The image itself stays editable without silent stretching. Use Fill the full composition after a size change if you want to recrop it.
What do the downloads contain?
Each PNG has the displayed pixel dimensions, including that panel’s wrap and bleed. Each production PDF has the matching physical page size and embeds those same pixels. The numbered Letter check is reduced to fit; its 100 mm ruler is for checking print scale. Output is RGB raster artwork, not CMYK or certified PDF/X.
Can I print one panel or correct it separately?
Yes. Choose Left, Center or Right, then download just that panel’s PNG or PDF. Its horizontal and vertical corrections move the artwork without changing the panel’s physical size. Corrections are optional and are listed in the size file and installation check.
Are my files private?
Images stay in this browser session. Text and measurements are saved on this device, not photo bytes. Save project downloads a private ZIP with original photos; restore them after reloading or reopen the ZIP. No image upload occurs, though the website still makes normal page requests.
What should I check with my printer?
Confirm finished dimensions, mounting gaps, wrap depth, fastening allowance, bleed and color requirements. Pixel edges are rounded to the nearest pixel. Each panel is limited to 24 million output pixels, with safe input and session limits. If a panel is too large, reduce resolution. Make one physical sample; no universal supplier fit is assumed.
