Join Photos Into One File

This stitches files into one even image. It is not Collage Maker. Use a row, stack, or simple grid when you need one joined file, then open Collage Maker for decorative presets.

Stitch Files, Do Not Decorate Them

Stitch Files, Do Not Decorate Them

Even Row, Stack, or Grid

Place source files in one horizontal row, a vertical stack, or an even grid. Every tile is the same size. Reorder the list so the finished file reads left to right or top to bottom.

Not Collage Maker

Collage Maker is for creative preset layouts, uneven frames, and social templates. This tool only joins files into one even image. If you want a decorative collage, use Collage Maker instead.

Private Browser Processing

The browser decodes and draws the images on this device. The files are not sent to an image-processing server, and the temporary working data disappears when the page closes.

PNG for Graphics

Use PNG for screenshots, text, logos, or images that need crisp edges. PNG is lossless but usually creates a larger file.

JPG for Photos

Use JPG for a smaller photo file that is easy to email or post. Transparent areas are filled with the background colour because JPG does not support transparency.

Practical Limits

Join 2 to 12 files, with a 20 MB and 32 megapixel limit per source image. Those bounds keep the canvas responsive and avoid browser memory crashes.

How do I join images into one file?

  1. 1

  2. 2

    Step 2: Pick a Join Layout

    Choose horizontal, vertical, or an even grid, then reorder the files and adjust fit, spacing, and background.

  3. 3

    Step 3: Download One Image

    Choose PNG or JPG and save the joined result. Use Collage Maker if you wanted a decorative template instead.

Fast and Straightforward

Resizing photos for social media should be a cinch, but most editing programs are a pain to use. Of the dozen I’ve used, Instasize is the fastest, easiest and most consistent...
