Why use it
Why use our Convert Image tool
All the common formats
Convert to JPG, PNG or WebP everywhere, and to AVIF in browsers that can encode it — detected automatically.
Transparency handled
PNG and WebP keep transparent backgrounds; for JPG you choose the colour that fills them instead of ugly black.
Reads iPhone HEIC photos
HEIC/HEIF files are decoded right in the browser, so you can convert iPhone photos to any format.
Batch conversion
Convert a whole set of images at once and grab them in one zip file.
Private by design
Every conversion happens on your device. No uploads, no accounts, no watermarks.
FAQ
Frequently asked questions
Which format should I choose?
JPG for photos that must open everywhere, PNG for screenshots, logos and anything needing pixel-perfect edges or transparency, WebP for the smallest web-ready files with transparency, AVIF for even smaller files on modern sites.
Why is AVIF not offered in my browser?
Most browsers can display AVIF but not all can create it. We test your browser's encoder and only show AVIF when it actually works. You can still use AVIF files as input.
What happens to transparent areas when converting PNG to JPG?
JPG has no transparency, so transparent pixels are filled with the background colour you choose — white by default.
Can I convert an animated GIF?
The first frame is converted to a still image. Animation isn't preserved when converting to JPG, PNG or WebP here.
Is converting to WebP or AVIF safe for my website?
Yes — WebP is supported by every modern browser, and AVIF by all current versions of Chrome, Edge, Firefox and Safari.
