常见问题
Are my pictures uploaded?
No. Each picture is decoded and re-encoded on a canvas inside this page. Nothing crosses the network, so there is no copy on anyone else’s computer.
Why did one of my pictures get bigger?
It usually means the original was already compressed harder than the quality you asked for, or that a PNG of a photograph was turned into a format that suits it less well. When the result would be bigger, the original is kept and downloaded unchanged.
Does it remove the location data?
Yes, as a side effect. The picture is redrawn from its pixels, so EXIF data — including GPS coordinates, camera model and timestamps — is not carried into the new file. That is usually what you want before sharing a photo.
JPG or WebP?
WebP is typically 25–35% smaller than JPG at the same visible quality and every current browser supports it. Choose JPG when the file has to open in older software that may not know WebP.
