MergePNG
Live this weekMerge PNG files locally, no upload
About
MergePNG is a browser-based tool that lets you combine multiple PNG files into a single image. You can arrange them side‑by‑side, stack them vertically, or create a grid, all while keeping the original transparency and image quality. Unlike many online services, MergePNG processes everything locally on your device, so no files are uploaded and no watermark is added.
The case
Who it is for
Graphic designers, UI/UX teams, and product managers who need to quickly merge screenshots, icons, or product images without installing software or uploading sensitive content.
What is broken today
Before MergePNG, users who wanted to combine PNG images had to rely on desktop applications or cloud services that required uploading files, risking privacy, or installing complex software. These solutions often added watermarks, altered transparency, or lacked simple layout options.
What it does about it
MergePNG loads PNGs into the browser, decodes them locally, and offers a drag‑and‑drop interface to reorder and choose layout (horizontal, vertical, grid). The tool renders a preview, lets you adjust spacing, background, and output format, then exports the merged image directly to your device.
Why not the obvious alternative
MergePNG runs entirely in the browser, so files never leave your device, guaranteeing privacy. It preserves PNG transparency and quality, offers natural filename sorting, checks canvas size before export to prevent failures, and supports custom background colors and border widths—features missing or limited in many free online PNG mergers.

Questions
- How do I combine two PNG files into one?
- Add both images to the PNG merger, drag them into the correct order, choose a horizontal, vertical, or grid layout, preview the result, adjust spacing or background if needed, and click Download Combined PNG to save the merged image on your device.
- Is this PNG merger free?
- Yes. The first release of MergePNG lets you merge PNG files for free without creating an account or adding a watermark.
- Will my PNG files be uploaded?
- No. The files are read by your browser and processed on your device. MergePNG does not need to upload the source images to create the result.
- Can I export the merged image as JPG or WebP?
- Yes. PNG is the default output for transparency, but you can also export as JPG or WebP. JPG uses a solid background because it does not support transparency.
- How are very large PNG merges handled?
- Browsers limit canvas dimensions and memory. MergePNG checks the estimated output size before export and asks you to reduce scale, dimensions, or file count when the final image is too large.
