Every pixel
The image is decoded band by band and rewritten, so what comes out is what went in rather than a screenshot of a preview.
Convert JPEG to WebP Online
Convert JPEG images to WebP in your browser. Small files at the cost of detail, which matters more in imagery than most people expect becomes smaller than PNG at the same quality, for putting imagery on the web, with nothing uploaded to a server.

Filled in from the file when it says. For a picture that does not, put the corners in and it becomes a GeoTIFF.

How to convert JPEG to WebP
-
1
Choose your JPEG file
Drag it onto the panel or browse for it. It is read straight from your disk and decoded in the browser, so nothing is uploaded however large it is.
-
2
Check what came in
The size, band count, bit depth and compression are listed, along with whether the file says where on earth it sits. A sixteen-bit raster is stretched for the preview so you see the image rather than a black rectangle.

Download the WebP
WebP cannot hold a position, so if the source was georeferenced take the world file written beside it. Without that, the image no longer knows where it belongs.
What comes across
JPEG carries more than geometry, and most converters drop the rest. This one does not.
A world file, so the place survives
The position cannot live inside a WebP, so it is written to a sidecar file beside it. Keep them together and a GIS will still place the image correctly.
What the file actually is
Bands, bit depth, compression, tiling and coordinate system are all reported before you convert, which is often the answer somebody was after anyway.
Frequently asked questions
Is my image uploaded anywhere?
No. The whole thing is decoded and rewritten in your own browser. Nothing is transmitted, which matters for survey imagery that is not yours to share.
Does the position survive?
WebP has nowhere to keep a position, so it cannot. A world file is written alongside instead, and the image is only georeferenced for as long as the two stay together.
Which TIFF variants can it read?
Uncompressed, LZW, deflate and PackBits, tiled or stripped, 8 and 16 bit, one band or several. Sixteen-bit data is stretched for display so you see the image rather than a black rectangle.
What image size can I convert?
Large files are read fine. Anything over about six thousand pixels across is scaled for the preview and for picture output, and the figures shown always describe the original.
Do I need an account?
No. No sign-up, no email address, no watermark on the result.

SVG is an export format only — you can convert any layer into it, but not back out again. A drawn map has no coordinates to recover, only shapes on a page.
