Choose the output for its destination

This converter runs locally in your browser. Convert a representative image first and check the result where it will actually be used.

  • Input: HEIC, HEIF, JPG, PNG, WebP, or AVIF; output: JPG, PNG, WebP, or AVIF.
  • Convert up to 20 files, 30 MB and 40 megapixels each; resize retains the aspect ratio.
  • JPG cannot keep transparent pixels, so choose a background color before converting transparent artwork.

Images are decoded, resized, and converted on this device; they are not uploaded to the server.

HEIC, WebP, AVIF, PNG, or JPG: How to Choose an Image Format

Choose an image format for the use case

Before you start

  • Confirm whether the destination needs transparency, animation, or broad browser support.
  • Keep the original file when converting from a newer or higher-quality format.

Check the result

  • Verify dimensions, transparency, orientation, and visible detail after conversion.
  • Open the result in the app or browser where it will be delivered.

Know the limit: A format conversion can discard features such as layers, animation, metadata, or transparent pixels.

What This Tool Does

The converter decodes HEIC, HEIF, JPG, PNG, WebP, and AVIF locally, optionally resizes each image, and exports JPG, PNG, WebP, or AVIF. Web Workers and WebAssembly keep processing off the server.

Common Use Cases

  • Convert iPhone HEIC photos to widely compatible JPG or PNG
  • Open WebP or AVIF images in software that expects JPG or PNG
  • Create smaller WebP or AVIF assets for websites
  • Convert a batch of images and download the results as one ZIP

How Data Is Handled

Images, file names, and converted results stay in your browser and are never uploaded to MV Tools. Metadata such as EXIF and GPS is removed from converted output.

FAQ

Are my images uploaded?

No. Decoding, resizing, conversion, and ZIP creation happen locally in your browser.

Why can AVIF conversion take longer?

AVIF encoding is computationally intensive, especially for large images and on mobile devices.

Does the converter preserve metadata?

No. Converted files do not preserve EXIF, GPS, or other source metadata, which also helps protect privacy.

What happens to transparency when converting to JPG?

JPG has no transparency. Transparent pixels are filled with the background color you choose.
