About the Image Converter

Different platforms expect different formats — JPG for photos, PNG for transparency, WebP for the smallest web files, and HEIC for iPhone photos. The converter switches between them instantly in your browser, flattens transparency onto a background colour when you export to JPG, and lets you tune quality. Use the popular conversions below to jump straight to a specific one.

Frequently asked questions

Which formats can I convert between?

You can export to PNG, JPEG or WebP, from PNG, JPG, WebP, BMP, GIF and HEIC/HEIF (the format iPhones use).

How do I convert HEIC to JPG?

Drop your .heic file and choose JPEG as the output. The converter decodes HEIC right in your browser and gives you a standard JPG to download.

What happens to transparency when I convert to JPEG?

JPEG doesn't support transparency, so transparent areas are filled with a background color you pick (white by default). Choose PNG or WebP to keep transparency.

Are my images uploaded to a server?

No. Conversion runs entirely in your browser, so your files never leave your device.
