Universal Image Converter is a private, browser-based image converter for changing one image or a whole batch of images into PNG, JPG, WebP, or AVIF. Conversion happens on your device, so files are not uploaded to a server.
How to convert images
- Browse for images or drag multiple files into the converter.
- Choose PNG, JPG, WebP, AVIF, or BMP as the output format.
- Adjust quality for JPG, WebP, or AVIF when needed.
- Download one converted image or download the completed batch.
Supported image formats
The converter accepts image formats your browser can decode, including JPG, JPEG, PNG, WebP, GIF, SVG, AVIF, BMP, HEIC, HEIF, and many camera or document formats when browser support is available. PNG, JPG, WebP, BMP, and AVIF are available as client-side output formats; AVIF decoding and export depends on the browser.
Frequently asked questions
What image formats can I convert?
You can select JPG, JPEG, PNG, WebP, GIF, SVG, AVIF, BMP, and other image files your browser can decode. The available output formats are PNG, JPG, JPEG, WebP, AVIF, BMP, GIF, SVG, ICO, TIFF, TGA, PPM, XBM, PSD, and browser-dependent JP2.
Can I convert multiple images at once?
Yes. Select or drop multiple images, choose one output format, and download each converted image from the responsive preview grid.
Are my images uploaded?
No. Images are decoded and re-encoded locally with your browser's canvas API. Your files never leave your device.
Why is AVIF sometimes unavailable?
AVIF export depends on the browser's canvas support. If your browser cannot create AVIF files, choose PNG, JPG, or WebP instead.
What happens to transparency?
PNG, WebP, and supported AVIF exports can preserve transparency. JPG does not support transparency, so transparent areas become white.
