Convert between JPG, PNG, WebP, GIF, BMP, SVG, AVIF, ICO, HEIC and more - instantly in your browser. No uploads, no sign-up, completely free.
nconverter.com processes every image directly inside your browser using the Web Canvas and File APIs - your files are never uploaded to any server. That means no waiting for a round-trip to the cloud, no privacy risk, and no dependency on an internet connection once the page has loaded. Whether you are converting a single photo or a batch of dozens, your data stays entirely on your device.
We support all the formats you are likely to encounter: JPG, PNG, WebP, GIF, BMP, SVG, AVIF, ICO, and HEIC. Each tool is purpose-built for its specific conversion pair, so you get appropriate defaults - for example, PNG conversions default to lossless mode, while JPG and WebP conversions expose a quality slider so you can balance file size against visual fidelity.
Batch conversion is built in from the start. Drop a whole folder of images onto any converter and they are all processed simultaneously. When you are ready, download every converted file in a single click - no zipping, no extra steps. For teams and individuals who regularly process large sets of images, this saves significant time compared to converting one file at a time.
Every converter on nconverter.com is completely free with no account required, no watermarks, and no file-count limits. Switching to WebP across your website, preparing photos for a document, or extracting a PNG from an ICO favicon - whatever the task, the tool is ready instantly.
