AutoCropper's settings live in five places, each next to the work it affects: the Settings dialog, the toolbar's View menu, the Advanced Crop Editor's Editor preferences, the Export dialog and the upload page's Advanced options. This page lists every setting by where you find it, what it does and its default. All of them are remembered in your browser, not in your account: they stay the same on this computer until you change them, and do not follow you to another device or browser.

The Settings dialog#

Open it with the gear in the toolbar, or, on a narrower window, More options (the three dots), then Settings. On a phone it is in the menu at the top. Changes take effect when you press Apply; Cancel leaves everything as it was.

The Settings dialog on its Export tab: tabs for Export, Detection, Editor and Appearance down the left, the file naming options with a file name structure field and Pad numbers on the right, a Reset to defaults link at the bottom of the tabs, and Cancel and Apply buttons
The Settings dialog.
  1. Export tab. How exported files are named.
  2. Detection tab. Turning photos upright, and minor rotations.
  3. Editor tab. How the Advanced Crop Editor saves and rotates.
  4. Appearance tab. Light or dark theme.
  5. Reset to defaults. Puts every setting back to the stock values. You still need to press Apply.
  6. Apply. Saves the changes.

Export: file names#

  • File naming chooses between File name + number (photo_1, photo_2), the default, which names each photo after its scan and its position on it, and Custom template.
  • File name structure is the template, used only with Custom template. It is built from three placeholders, at least one of which it must contain, with no spaces: {file}, the scan's name without its extension (familyPhoto1989); {crop}, the photo's position on its scan; and {n}, its number across the whole batch. The default template is {file}_{crop}, so the third photo on familyPhoto1989.jpg becomes familyPhoto1989_3.jpg. {file} on its own names a scan that holds one photo after the scan.
  • Pad numbers (01, 02) adds leading zeros so files sort in order. Off by default.

A name typed on a photo, in the Name field of Crop options or in the editor, wins over both rules. Format, output size and capture margin are not here: they are set in the Export dialog, which remembers how you last exported (see below).

Detection#

The Detection tab: Detect upright orientation and Ignore minor rotations, both checked, each with its description, and a note that the detection algorithm is chosen on the upload page
The Detection tab of the Settings dialog.
  • Detect upright orientation turns photos that were scanned sideways or upside down the right way up. On by default. The same switch is on the upload page.
  • Ignore minor rotations sets a crop's tilt to zero when it is within 2 degrees of level, which avoids softening a photo by rotating it a fraction of a degree. On for new visitors.

The detection method itself is chosen on the upload page before you upload; see detection methods.

Editor#

The Editor tab: Auto-save, Rotation snap, a greyed-out Close editor after Apply, and Outline other crops in the editor, each checked with its description
The Editor tab of the Settings dialog.
  • Auto-save keeps every edit in the Advanced Crop Editor as you make it, so there is no Apply button and closing the editor any way keeps your changes. On by default.
  • Rotation snap makes a crop's rotate grip on the canvas snap to straight, and to quarter turns, when you are close: within about 1.5 degrees of level and about 4.5 degrees of a quarter turn. On by default. Turn it off for fine angles by hand.
  • Close editor after Apply closes the editor when you press Apply. It only matters with Auto-save off.
  • Outline other crops in the editor draws the scan's other crops as faint outlines while you edit one, so a photo without an outline stands out as missed. Click an outline to jump to that crop. On by default.

The first, third and fourth are also in the editor itself, under the gear at its top right (Editor preferences), so you can change them without leaving it.

Appearance#

Theme is Light, the default, or Dark. It applies to the cropping tool only, not to the rest of the site, and can also be switched from the View menu.

What Reset to defaults resets#

Everything the app remembers: the naming, detection and editor settings above, the View menu's outline settings, the Export dialog's remembered choices and the detection method on the upload page. They go back to what a first-time visitor starts with, including V7 detection.

The View menu: how crops look on screen#

The View menu open under the toolbar: a crop outline colour swatch, Thickness with S, M and L, Opacity with Faded and Solid, and Theme with Light and Dark
The View menu: how crop outlines are drawn, and the theme.
  1. Outline color. The colour of the crop boxes on the canvas. A mid blue by default.
  2. Thickness. Small, medium (the default) or large outlines.
  3. Opacity. Faded or solid (the default) outlines.
  4. Theme. Light or dark.

These change only what you see while you work, never the exported photos, and they apply the moment you click. To print a border into a photo, use Add border in the Advanced Crop Editor.

Editor preferences#

The Editor preferences menu with Auto-save changes checked, Close editor after Apply greyed out, and Outline other crops checked
The editor's preferences, behind the gear at its top right.

The same switches as the Settings dialog's Editor tab, without leaving the editor. Rotation snap is not here because it applies to the canvas.

The Export dialog remembers how you exported#

The format and quality, padding and background, capture margin, file naming and Ask me where to save are set in the Export dialog, and the choices you export with become the defaults for the next batch. The scan choice under Photos and Date taken are never remembered, because they describe one batch. The dialog's own Reset to defaults puts its options back to the stock values. See exporting crops.

The old Feather Crops setting is now the Export dialog's Capture margin: a percentage that grows or shrinks every crop around its centre when it is exported, without changing the boxes on the canvas.

On the upload page#

The upload card with Advanced options open, showing the Detection Method drop-down and the Detect upright orientation option
The upload card with Advanced options open.
  1. Detection Method. How photos are found on the next upload. V7 for new visitors.
  2. Detect upright orientation. The same switch as in Settings.

Questions#

Where did Feather Crops go?#

It is the Capture margin in the Export dialog, a percentage from minus 50 to plus 50.

Are my settings saved to my account?#

No. They are kept in this browser. Another browser or computer starts from the defaults, and clearing your browser's site data resets them.

How do I make the crop outlines thinner or a different colour?#

Open the View menu in the toolbar and change Thickness or the outline colour. Your exported photos are not affected.

How do I stop AutoCropper turning my photos?#

Turn off Detect upright orientation, in Settings on the Detection tab or on the upload page, before you upload.
