Merge PNG, JPG and WebP images into one file or PDF directly in your browser, without uploading anything.

MergePNG is a browser‑based tool that lets you combine PNG, JPG and WebP images into a single raster file or a PDF. You drag files onto the page, arrange them, choose a layout template and download the result—all in a few clicks. All processing happens locally with JavaScript and the Canvas API, so your files never leave your device. The tool works offline, preserves PNG alpha channels, and offers options for borders, corner radius, gaps, margins and scaling. It is aimed at anyone who needs to create collages, screenshots, sprites or simple PDFs quickly while keeping privacy. The interface supports mixed formats, duplicate detection via SHA‑256 hashes, rotate/flip per image, and touch‑friendly drag‑to‑reorder. Key differentiators include no upload risk, unlimited file count limited only by device memory, mobile‑browser compatibility, and a range of layout presets (stack, side‑by‑side, 2‑ or 3‑column grids, and compound combos).
