PNG Converter

This free online PNG converter turns JPG, WebP, GIF and BMP files into PNG — in batches, with no quality settings to fuss over, because PNG is a lossless format. Drop in as many files as you need and each one converts on its own, with a live before/after size and a one-click download, plus a "Download all" button once the whole batch is ready.

PNG is the format to reach for whenever quality and compatibility matter more than file size: it's the universal choice for logos, icons, screenshots, diagrams and any graphic with flat colors or sharp edges, because unlike JPG it applies no lossy compression that can blur text or introduce blocky artifacts around hard lines. It's also the format almost every design tool, favicon generator, app-store asset checker and print workflow expects by default — if something rejects a WebP or a GIF but needs a static image, PNG is the safe fallback that works everywhere.

Crucially, PNG is the one common format with full transparency support built in from the start, and this converter preserves it automatically: convert a transparent WebP or GIF and the transparency carries straight over to the PNG, ready to drop onto any background without a visible edge. Converting from a format that has no transparency, like JPG or BMP, simply produces a fully opaque PNG — exactly what you'd expect, with no extra steps or settings to configure.

Every conversion happens locally in your browser using the HTML canvas API — nothing is ever uploaded to a server, so it's instant, works the same on a phone as a laptop, and is the safest way to batch-convert private or unpublished graphics, since there's no upload and no server-side copy to worry about. A live totals panel shows the combined size of your original files next to the converted PNGs, so you know exactly what you're getting before you download.
