What This Tool Does
Side-by-side comparisons, Instagram carousels flattened to one frame, and documentation screenshots often need multiple pictures in a single asset. Our merger stacks images in a row (horizontal) or column (vertical), aligning them on a shared canvas with consistent spacing handled by the mergeImages engine.
Upload at least two images — order matters for left-to-right or top-to-bottom arrangement. Export as JPEG for photos, PNG for lossless composites, or WebP for modern web size savings. All compositing runs locally on XConverters so personal photos and confidential UI captures stay private.
No Photoshop required for simple collages. Free unlimited merges with no registration — ideal for quick social posts, bug report attachments, and before/after pairs.

Privacy and Security
Everything runs locally in your browser on XConverters. Your input is never uploaded to our servers, stored in a database, or shared with third parties. We designed this tool for developers, designers, and everyday users who need quick results without sacrificing privacy.
Only anonymous site analytics may be collected to improve performance and usability. The actual text, files, or data you process never leave your device during normal use.
Private by design: Because processing happens entirely in your browser, you can safely work with personal photos, client documents, API payloads, and proprietary content without exposing it to cloud storage.
Tips for Best Results
- Use similar heights for horizontal merges — extreme size differences leave empty bands.
- PNG keeps text sharp when merging screenshots; JPEG is smaller for photo collages.
- Reorder uploads if the sequence is wrong — first file is leftmost or topmost.
- Very wide horizontal merges may be large — check dimensions before sharing.
- Match output format to your platform — WebP for web, JPEG for email.
