Convert Image
Change an image’s format — PNG, JPG or WebP. The input can also be HEIC/AVIF/GIF (if your browser opens it). Processing is local, with no upload.
Flexible input
Convert from PNG, JPG, WebP, GIF, BMP and more that your browser can decode.
In your browser
The image is never uploaded — conversion is local.
Frequently asked questions
Is my image uploaded?
No. Conversion runs entirely in your browser — nothing is sent to a server.
Does it accept HEIC or AVIF input?
It depends on your browser. If it can open the format, the tool will convert it; otherwise the image won’t load.
When should I pick PNG, JPG or WebP?
PNG for transparency and lossless; JPG for photos and maximum compatibility; WebP for the smallest file at the same quality.
Is transparency preserved?
Yes — for PNG or WebP output. For JPG, transparent areas become white because JPG has no transparency.
