Convert Images to and from PNG Online

PNG sits at the centre of almost every graphics workflow, which is why conversion around it runs in both directions. Sometimes PNG is the destination: a JPG logo needs a transparent background, an iPhone HEIC has to become something Windows can open, or an upload form accepts nothing else. Just as often PNG is the starting point: a screenshot is too heavy for a web page, a favicon has to be an ICO, or a client’s CMS rejects the file your design tool exported. This converter covers both directions in one place. It reads JPG, PNG, WebP, SVG, HEIC, TIFF, BMP, and GIF, and it writes JPG, PNG, WebP, BMP, ICO, or GIF, so you rarely need to hunt for a second tool midway through a task.

Turning an image into PNG makes sense when the two things the format does uniquely well are what you actually need. PNG is lossless, so every pixel survives intact and sharp edges, small text, and line art stay crisp instead of collecting the smudged artefacts that JPG leaves around high contrast. PNG also carries a full alpha channel, so artwork cut out from its background keeps a genuinely see-through edge. Converting a WebP, SVG, or GIF logo into PNG preserves that transparency, where flattening the same file to JPG would trap a solid box around it permanently.

Turning a PNG into something else is almost always about size. Because PNG discards nothing, a photograph saved as PNG can be several times larger than the same picture as JPG or WebP, with no visible gain to show for the extra weight. Exporting that photo-heavy PNG to JPG or WebP usually shrinks it dramatically and makes pages load faster. The trade-off is transparency, which JPG cannot hold at all, so the tool reveals a background colour picker for exactly those formats, letting you choose the fill rather than inheriting an unexpected black.

Whichever direction you are heading, each format pair has its own page with guidance written for that specific combination. Coming into PNG, see JPG to PNG, WebP to PNG, SVG to PNG, HEIC to PNG, GIF to PNG, BMP to PNG, and TIFF to PNG. Heading back out again, see PNG to JPG, PNG to WebP, PNG to ICO, PNG to GIF, and PNG to BMP.

Underneath, every conversion runs locally in your browser through the Canvas API, so files never travel to a server and nothing lingers after you close the tab. There is no account to create, no daily cap to hit, and no watermark added to your exports, and the page keeps functioning offline once it has loaded. Drop a mixed folder into a single session and collect the results as one ZIP archive, which collapses what would otherwise be a long round of one-by-one conversions into a single step.
