JPG / JPEG
Best for realistic photos with smooth gradients. The free image converter creates compact JPG files in seconds, but transparency is not supported because the compression is lossy.
PNG
Ideal for logos, text, and screenshots. The image converter keeps every transparent pixel intact with lossless compression, even if that means creating a larger file.
WEBP
The modern web standard our image converter loves. WEBP supports transparency and animation while staying roughly 30% smaller than JPG at the same quality.
Privacy-first image converter.
Most image converters upload your sensitive documents to a cloud server. The NanoAI free image converter uses WebAssembly to process every pixel locally, even if you go offline.
- No server uploads
- Works offline
- Instant processing
