Convert Format
Convert images between JPEG, PNG, and WebP formats.
About Convert Format
Convert Format changes an image between JPEG, PNG, and WebP without touching its content. Use it when a site, app, or coworker needs a specific format, or when switching formats will save space, such as moving a photo to WebP or flattening a transparent PNG to JPEG. The conversion happens in your browser, so your image stays private.

Frequently asked questions
Which conversions are supported?
Any combination among JPEG, PNG, and WebP. You drop in one of those formats and choose which of the three to export.
What happens to transparency when I convert to JPEG?
JPEG has no alpha channel, so transparent areas are filled with a solid background. Use PNG or WebP if you need to keep transparency.
Is converting lossless?
PNG is lossless; JPEG and WebP are lossy and re-encode the pixels. Converting a JPEG to PNG won't restore detail already lost, it just stops further loss.
Does the file upload anywhere?
No. The whole conversion runs client-side in your browser, so the image is never transmitted to a server.
Can it convert HEIC or GIF?
Not currently. Accepted inputs are JPEG, PNG, and WebP only.
