Convert images between formats
PNG, JPG, WebP and AVIF — pick the output format and convert as many as you want at once.
Each image format has its purpose: PNG for lossless transparency, JPG for maximum compatibility, WebP for fast websites, and AVIF for the smallest possible size at great quality. This converter lets you switch between all of them in seconds — drop several images, pick the format and download everything as a ZIP.
It even accepts iPhone HEIC photos as input. And like every Imagia tool, the conversion happens entirely in your browser: your images are never uploaded to any server. Unlike traditional online converters, the photo never touches anyone’s cloud.

Frequently asked questions
Which format should I choose?
WebP and AVIF are the smallest, ideal for websites. PNG keeps lossless transparency. JPG is the most compatible for sending and printing. AVIF compresses best of all, but some older programs can’t open it yet.
Are my images uploaded to a server?
No. All conversion happens inside your browser. The images never leave your device.
Does it convert iPhone HEIC photos?
Yes. Drop the .heic files and pick the output format — the conversion runs instantly.
