Mac screenshots start at this toolbar

Toolbar

Your floating gateway to capture and tools on the desktop

Pick the color of any point on screen; switch and copy HEX / RGB / HSL in one click. Frequent colors are saved to Recents and stay in sync with the editor's palette.

Drag a box that snaps to edges to measure pixel dimensions, or click two points for point-to-point distance. Measurement lines can be selected, deleted, undone and redone.

Tauri onlyEvery capture goes in. Find last week’s shot without having to remember where you filed it.

After a capture you usually do one of two things: save it, or forget it. Screenshot History is a third option — every capture stays in the history automatically, from all six sources: the four capture modes, scrolling capture, ruler output and clipboard paste. It is a window of its own, not a drawer inside the editor: save, close the editor, and the history is still there — the moment you need to find an image is precisely the moment the editor is long gone.

• How to open it — the Open button in the toolbar, Screenshot History in the menu bar, or the global shortcut ⌥ ⌘ G. To go straight to the file dialog instead, hold ⌥ and click Open; “Open from File…” at the top right of the window is the same route.
• How to find something — the thumbnail wall is grouped by day, newest first, and every tile is labelled with the time, the capture type, the source app and the size. The two filters above narrow it to one type or one source.
• Once you have found it — four actions per tile: Copy Image (paste it to someone without opening the editor), Open in Editor (re-annotate the original), Show in Finder, and Delete. To empty the whole history, Clear All asks twice.
• How much it keeps — 300 entries; past that the oldest are dropped automatically. A Retina capture lands at roughly 4.4 MB, so 300 of them is about 1.3 GB — that is a disk matter, not a speed one: the list reads only the index, and thumbnails load as you scroll.
• Window behaviour — any toolbar function other than Open closes the history (you clearly meant something else); collapsing to the breathing light does not (you may still be looking); and it closes at the instant of capture, so it never ends up inside your screenshot. Its position is remembered, and it reopens where you left it.

Convert many images to one format in a single pass — and while converting, resize them uniformly, add a watermark, and choose where they save. Made for processing large batches of screenshots or assets.

Add files

• Drag images into the window, or click “Select files” to pick them; you can also “+ Add files” to keep adding.
• Up to 100 images per run.

Supported formats

• Reads — PNG, JPG/JPEG, WebP, GIF, BMP, TIFF, SVG (vector art is rasterized inside the app).
• Writes — PNG, JPG, WebP, GIF, BMP, TIFF — six formats. Tauri onlyBMP and TIFF are Tauri-only.
• When writing JPG/WebP you can set quality (1–100%); if the batch contains SVGs you can set the SVG output width (which decides the rasterization resolution).

Resize All (optional)

• Fix the width or the height to a set pixel value; the other side scales proportionally.

Watermark (optional · text and image can be used together)

• Text watermark — enter the text (Chinese and Japanese supported), size, color, opacity, and a nine-grid position (corners / edges / center).
• Image watermark (logo) — pick an image, set its width ratio (relative to the original), opacity, and nine-grid position, with a live preview.
• Both share the margin setting; when both are on, text sits below and the image on top.

Save location

• The same folder as the source files, or a folder you choose.
• You can tick “Delete originals after converting” — the originals go to the Trash (still recoverable, not permanently deleted).
• Progress shows image by image as it converts.

Breathing Light & Summon

When you're not using VAS but still want it standing by, small and quiet on your desktop, turn on breathing-light mode from the “Keyboard Shortcuts” button.

The toolbar shrinks to a single 120×6px sliver of light — understated, out of the way, quietly waiting for you.

And when you need to reach for it:

• All versionsDrag an image close — the toolbar opens like a Venus flytrap and catches the image you bring it. The moment you let go, the image drops straight into the editor; if you were already editing something else, it tucks that away and reopens the editor so you can keep going.
• Tauri onlyDrag an image out to export — the editor collapses like a black hole, giving you the maximum desktop space and view to save or hand off. Drag in a single motion to any window / dialog / folder, however you like. The moment you let go, it reopens the editor so you can keep going.
• Tauri onlyCopy an image from your browser — a toast pops up asking whether to “paste the image”; say yes and it drops straight into the editor. Or paste it into the editor directly with your own custom shortcut.

The Bottle in the Menu Bar

That bottle in the top-right of the menu bar is the entry to VAS's system menu. Two ways to click it:

• Left-click — quickly toggle the desktop toolbar's show / hide. For the desktop minimalist, an option to keep nothing on the desktop at all.
• Right-click — open the system menu to run every toolbar function in full, without summoning the toolbar itself.

If you'd rather see no trace of VAS on your desktop at all, left-click to turn the toolbar off — right-click still gives you every toolbar function.
