Online Screenshot Editor

Paste an image, fix it, download it. No install, no upload, no watermark.

Free, no watermark, nothing uploaded. Needs a free Demorta account.

You have a screenshot already -- from your phone, from a colleague, from the OS shortcut -- and it needs a crop, an arrow and a name blurred before it goes anywhere. Opening a desktop editor for that is more ceremony than the edit deserves.

This editor runs in the browser. Paste with Ctrl+V, drop a file, or open one. Edit. Download. The extension is optional: it adds the capture step, but the editor works on any image without it.

STEP 1
Open the editor

Sign in to Demorta and open Screenshot tool from the dashboard. No extension needed for this route.

STEP 2
Paste or drop an image

Ctrl+V from the clipboard, drag a file onto the editor, or click Open image. PNG, JPG and WebP.

STEP 3
Edit

Crop first, then box, arrow, text, pen, highlighter, or blur. Undo anything.

STEP 4
Download or copy

A PNG to your Downloads folder, or the clipboard for pasting straight into a message.

Tools

  • Crop -- drag a region, Apply crop.
  • Box, arrow, pen, highlighter -- in a chosen colour and thickness.
  • Text -- with an automatic outline for readability.
  • Blur -- pixelation coarse enough to be irreversible.
  • Undo / redo -- Ctrl+Z, Ctrl+Shift+Z.
  • Copy -- edited image straight to the clipboard.

Why in the browser, and why local

Because the edit is small and the image is often private. A desktop editor is too much for a crop and an arrow; an upload-to-edit website is too much exposure for an image of your inbox. A browser editor that never sends the image anywhere is the right size for the job.

With the extension

Installing the Demorta extension adds the capture step: press Screenshot or Ctrl+Shift+8 on any page, drag the area, and the editor opens with it loaded. Without the extension, the editor is still here for images from anywhere else.

Questions

Is there a free online screenshot editor with no watermark?

Demorta’s screenshot editor is free with a free account, adds no watermark, and works on any pasted or dropped image in the browser.

Do I need the extension to use the editor?

No. The editor is a page in the dashboard and accepts pasted, dropped or opened images. The extension only adds capturing from a page.

What formats can I edit?

PNG, JPG and WebP in; PNG out, or the clipboard.

Is my image uploaded?

No. Everything happens in your browser tab and the download is local.
