Seamless / Screenshot stitching

The whole story.
In one image.

Turn overlapping screenshots into one continuous image. Keep a conversation, save a useful thread, or share the details—without sending a stack of screenshots.

Bring it together

Keep the context.
Lose the juggling.

One image is easier to follow.

A conversation that spans several screens. Instructions you want to keep. A thread worth sharing. Seamless finds the overlap between screenshots and joins them from top to bottom.

Your selected order stays yours. Preview the result, inspect the joins, then save to Photos or share a PNG to Files and other destinations.

Made for overlapping screenshots of the same content at the same width and zoom. Seamless does not invent missing content or force an uncertain join.

From a few screens to one story

Select. Stitch. Share.

01 / Select

Start with your screenshots.

Choose 2–20 overlapping screenshots. Put them in reading order, from top to bottom, and replace or remove any you don’t need.

02 / Stitch

Let the overlaps line up.

Seamless checks neighboring images and joins the matching content on your device. If a join is uncertain, it pauses for your review.

03 / Share

Send the whole picture.

Zoom into the preview, show join markers, and export a PNG at the original pixel width. Save it or share it where you choose.

Thoughtful where it counts

A cleaner result.
A little more care.

Original pixels. Crisp output.

Seamless keeps the original image width and exports a PNG. No blending or recoloring your content. Your source screenshots stay unchanged.

Every join earns its place.

An uncertain match stops the stitch. Adjust your screenshots or choose to preview the successfully joined beginning. Nothing is silently skipped.

Check before you share.

Pinch to zoom and reveal the join markers in the preview. Those markers stay out of your exported image.

Private by design

Your screenshots.
Your business.

The stitching happens on your device.

  • No upload to Arc Signal. Seamless analyzes and renders images locally. No account, ads, or analytics.
  • Your originals stay untouched. Working copies are temporary and cleared when you start a new stitch or restart the app.
  • You choose the destination. Save to Photos, share to Files, or send the finished image through another app. Source photo metadata is not copied into the PNG.

Apple’s photo picker may retrieve originals from iCloud. Photos, Files, and sharing destinations may sync or upload images according to your settings. The content visible in your screenshots remains in the image you share.

Good questions

Before you
bring it together.

What kinds of screenshots work best?

Use a sequence of overlapping screenshots from the same conversation, page, or other scrolling content. Keep the image width and zoom consistent, leave a clear overlap, and arrange them from top to bottom. Heavily cropped or unrelated images may not join.

What happens if the images don’t line up?

Seamless stops at an uncertain or incompatible join. You can change the selection or, when at least two images have joined successfully, choose to preview that continuous beginning. Review the result before saving; no missing content is generated.

How many screenshots can I combine?

Select 2–20 screenshots per stitch. Very large images or unusually tall results can exceed processing limits; use a shorter sequence if prompted.

Which devices will Seamless support?

Seamless is designed for Apple iPhone with iOS 18 or later. App Store availability is coming soon.
