Convert to WebP
Drop in any image and get a WebP: the small format websites use to load fast. Transparent backgrounds stay transparent, and nothing leaves your device.
Convert to WebP from
- PNG to WebP converterConvert PNG images to WebP in your browser: much smaller files, transparency kept. Batch convert any number; nothing is uploaded.
- JPG to WebP converterConvert JPG photos to WebP in your browser for smaller, faster web pages. Batch convert without limits; nothing leaves your device.
Why WebP?
WebP stores the same picture in noticeably fewer bytes than JPG or PNG, which is why websites use it to load faster. It keeps transparent backgrounds like PNG and handles photos like JPG.
Convert to WebP when you are putting images on a website or a shop listing. For sending photos to people or printing, JPG is still the safer choice, because some older programs don't open WebP.
Questions
Are my files uploaded anywhere?
No. The conversion runs inside your browser, on your own computer or phone. Your files are never sent to a server, so nobody else can see them.
Is there a limit on how many files I can convert?
No daily limit and no sign-up. Drop as many files as you like; the only limit is your device's memory, so very large batches simply take longer.
Which images can I convert?
HEIC and HEIF photos from iPhones, WebP, AVIF, PNG, JPG, GIF and BMP. Drop any of them; the converter recognises each file by its content, not its name.
Will every program open a WebP?
Every current browser does, and most image editors. Some older programs and upload forms still don't, so keep a JPG or PNG where that matters.
