ShareX

One file, one double-click, and every screenshot you take lands here.

Setting it up

Download the file above.
Double-click it. ShareX asks whether to set ovo.sx as your image, text and file uploader — say yes.
That's it. Take a screenshot; the link is on your clipboard.

If you'd rather do it by hand, it's Destinations → Custom uploader settings → Import → From file, then set ovo.sx as the destination under Destinations.

Pick your settings first

The download above uses the defaults: uploads are kept, and metadata is stripped — from video and audio as well as images. If you'd rather bake a different choice into the config, grab one of these instead — each is a separate entry in ShareX's destination list, so you can keep several and switch between them.

keep forever stays up until it is taken down
1 hour deletes itself 1 hour after upload
1 day deletes itself 1 day after upload
7 days deletes itself 7 days after upload
30 days deletes itself 30 days after upload
keep metadata leaves EXIF, GPS and camera data on your images

Or wire it up yourself

Any tool that can POST a file will do. There is no key and no account — one multipart/form-data request with the file in a field called file:

curl -F "file=@shot.png" https://ovo.sx/api/upload.php

You get JSON back:

{
  "ok": true,
  "id": "aB3dK",
  "ext": "png",
  "bytes": 48210,
  "url": "https://ovo.sx/aB3dK.png",
  "expires_at": null,
  "stripped": true
}

Two optional fields go alongside the file:

expires — seconds to keep it. One of 0, 3600, 86400, 604800, 2592000 . 0 means keep it. Anything else is refused.
strip_exif — 1 to remove metadata (images, video and audio alike), 0 to leave it. Defaults to 1.

On a failure you get {"ok": false, "error": "…"} and a 4xx status. The error string is written to be shown to a person as-is.

About the mark

The glyph on this page is ShareX's own logo — four interlocking crescents — reduced to its skeleton: each crescent drawn as a single stroked arc in our lilac, so it matches the rest of the site and loads as part of the page rather than from anyone else's server. ShareX is a free and open-source project, and is not affiliated with ovo.sx. The mark is theirs; it's here to say "this works with that", nothing more.
