Split an Image Into 3 Equal Parts

To split an image into 3, drop it into the splitter above. It cuts into three equal vertical panels by default, left to right, and you can drag the two cut lines to move the seams. Download all three as a ZIP or one at a time. Everything runs in your browser.

Three panels is the Instagram carousel shape. Post a wide photo as one square and it shrinks; post it as three slides that swipe into each other and the whole thing fills the screen.

That is what this preset is set up for. One row, three columns, cut left to right in posting order. A 3000 × 1000 panorama becomes three 1000 × 1000 px panels, each one close to square. Turn on 4:5 padding and each panel is placed on a 1080 × 1350 px canvas with a background of your choice, so Instagram shows what you exported instead of cropping into it.

Three is also the triptych number in print. A living-room wall gets three canvases with a finger of space between them, and the picture reads across the gap. Split at 1:3 for that, print each panel at full resolution, and leave the mounting gap to the frames rather than the file.

If you want a stacked cut instead of a side-by-side one, the axis toggle turns three columns into three rows. Same three files, rotated ninety degrees in intent: a long infographic cut into three postable strips rather than a wide photo cut into three panels.

Nothing is uploaded. The split runs on a canvas inside the page, which is why it finishes as fast as your machine can draw and why a photo you would rather not hand to a server stays on your machine.

What this split is used for

Instagram carousel triptych

A wide photo split into three panels swipes as one continuous image. Turn on 4:5 padding so each slide sits on a 1080 × 1350 px canvas and Instagram does not crop into your composition. Upload the panels in order, left first. All slides in a carousel have to share one aspect ratio, so pad every panel the same way.

Three-panel canvas print

Split a wide photo into three equal panels and print each at full size for a triptych. A 6000 × 2000 source gives you three 2000 × 2000 px panels, which is plenty for a large canvas. Line the horizon up so it carries across the gaps, and keep faces away from the two seams.

Wide screenshot into three slides

Gantt charts, spreadsheets and timelines are wider than they are readable. Cut a screenshot into three vertical slices and put them on consecutive slides or carousel cards, and the text stays at a size people can actually read. PNG keeps the letterforms crisp.

Three-across profile row

One picture stretched across three grid squares makes a header row on a profile. Split into three, then post the right-hand panel first and the left-hand panel last, because feeds fill in from the top left with the newest post. Preview the row before you commit to the order.

Tips

  • Turn on 4:5 padding for Instagram so the platform shows your panel instead of cropping into it.
  • Drag either cut line to keep a face or a horizon feature away from a seam.
  • A source close to 3:1 gives three near-square panels, which suits both carousels and square frames.
  • Upload carousel slides left to right, and grid tiles right to left, because a feed shows the newest post first.
  • Use the axis toggle to cut three stacked strips instead of three side-by-side panels.

Frequently asked questions

How do I split one image into 3?

Open the splitter on this page and drop in your file. The preset is already one row by three columns, so three equal panels appear in the preview. Drag the cut lines if a subject sits on a seam, choose PNG, JPG or WebP, then download the three files individually or in one ZIP.

How can I split an image into multiple images?

Pick the number of pieces you want and the tool cuts the source into that many separate files. Three columns gives three side-by-side panels. Three rows gives three stacked strips. Any grid up to 20 by 20 works, and every piece downloads as its own image file with a numbered name.

What is the best free app for splitting pictures into 3?

You do not need an app. This page splits in the browser using the Canvas API, with no sign-up, no watermark and no limit on how many images you run through it. Because your file is never uploaded, it also works on photos you would not want to hand to a server.

How do I split an image into 3 for Instagram?

Use the three-column preset with 4:5 padding switched on. Each panel is centred on a 1080 × 1350 px canvas with a white, black or blurred background, so the crop Instagram applies to tall images never eats into your picture. Post the panels in order, starting with the left one.

How do I split an image on my iPhone?

Open this page in Safari, tap the upload area and pick a photo. The cut lines respond to touch, and the panels save to Files or Photos. Photos shot in HEIC need converting first. Set Settings, Camera, Formats to Most Compatible and new shots save as JPG.

Can I split an image into 3 and keep it as PNG?

Yes. Choose PNG as the output format and each panel is written losslessly with transparency intact. PNG panels are larger than JPG ones, often several times larger for a photograph, but nothing is re-encoded and flat colour or text stays perfectly clean at the edges.

Are the three parts exactly equal?

They are equal to the pixel wherever the width divides by three. A 3000 pixel wide image gives three 1000 pixel panels. When the width does not divide evenly, the first two panels take the rounded-down width and the last one absorbs the extra one or two pixels, so nothing is lost.
