Merge Images Online Free — PrivaTools

TL;DR: Upload 2+ images and download a single merged image — horizontal or vertical stitching.

Merge multiple images online for free — combine JPG, PNG, and WebP files side by side or stacked vertically into a single image. Set spacing, alignment, and background color.

Using Merge Images doesn't require an account, an email address, or a paid plan. Your file is held in temp memory only for the duration of processing, then permanently unlinked. No watermarks, no upsells, no behavioural tracking.

How to Use Merge Images

  1. Upload 2+ images — JPG, PNG, WebP — at least 2 files.
  2. Choose direction — Vertical: top-to-bottom (good for screenshots in sequence). Horizontal: side-by-side (good for before/after).
  3. Download the merged image — Each input is scaled to a common dimension and concatenated.

Frequently Asked Questions

Will images be cropped?

No — they're scaled to a common dimension (width for vertical, height for horizontal). Smaller images upscale; larger images downscale.

What if my images have different aspect ratios?

They get letterboxed (transparent padding) to fit. Use Resize Crop Image first to force a common aspect ratio.

Difference from Make Collage?

Merge concatenates in a single row or column. Collage arranges in a grid with configurable columns.
