Image editor

Images placed in a note come with a built-in editor for small adjustments — cropping, straightening a crooked photo of a document, converting to grayscale, fixing brightness and contrast, or lightening the background of a scan. The key point is that it is non-destructive: before the first edit is applied, the original file is backed up, and your settings are stored as an editing recipe. You can reopen the editor at any time, change or turn off any adjustment, and every new result is computed from the original again — or go back to the untouched original with one click. This page explains how to open the editor, what each tool does, and how to re-edit and revert.

Open the editor

The editor is opened from an image that is already in the note. There is no separate menu: you start from the image itself.

1. 1In the note editor, click the image you want to adjust to select it.
2. 2In the image's floating bar, click "Edit image".
3. 3The "Edit image" window opens, with the image on the left and the tools on the right.

Two modes: Crop and Perspective

At the top of the tool panel you choose between two geometry modes — they are alternatives, and the editor keeps the one you apply:

Crop

Trims the image and straightens small tilts. Drag the frame's corners to define the area to keep ("Drag the corners to crop."), and use the "Rotation" slider — free rotation from 0 to 360°, in half-degree steps — or the "Left"/"Right" buttons for quick 90° turns.

Perspective

Straightens images shot at an angle, like photos of documents. "Drag the 4 corners" onto the document's real edges and the editor flattens the marked area into a straight, front-facing rectangle — as if it had been scanned. "Reset" puts the corners back in place.

Adjustments

The adjustments below work in both modes and can be freely combined:

Grayscale

A switch that removes the colors and converts the image to shades of gray. Good for documents, where color adds nothing.

Remove shadows

A switch designed for paper scans: it evens out the lighting, tones down shadows and stains, and makes the background whiter and the writing more legible.

Brightness

A slider (50–180%) that lightens or darkens the image as a whole.

Contrast

A slider (50–200%) that increases or reduces the difference between light and dark areas — more contrast highlights text and edges.

The "Scan" shortcut

The "Scan" button applies a ready-made combination for photographed documents: it turns on grayscale and shadow removal and raises brightness and contrast to good values for paper. Use it as a starting point and fine-tune afterwards; "Reset adjustments" clears everything back to neutral.

Apply

When you click "Apply", the note starts showing the edited version (saved in the light WebP format, with an updated thumbnail). Behind the scenes, the first edit backs up the original file, and your settings are stored as the image's editing recipe. The note's text is not touched — the image simply changes in place, everywhere it appears.

Re-edit and revert

Because the original and the recipe are kept, no edit is ever final:

• Reopen the editor on an edited image and it loads the original plus your saved settings — exactly as you left them.
• Change or turn off any adjustment (for example, disable only "Grayscale") and click "Apply" again: the result is recomputed from the original, so quality never degrades from editing repeatedly.
• To discard everything, click "Reset to original" (shown at the bottom once the image has edits) — the untouched file and its thumbnail are restored.
