What it does
Tamofy makes it fast to mark up screenshots and images - with arrows, readable text, highlights, drawings, counters, magnification, and pixelation.
Features
Six things worth knowing up front.
PNG, JPEG and HEIC
All three open, and a saved document keeps the picture in the format it arrived in.
Undo everything
Including a crop and a pixelation, until you deliberately flatten it.
One window per picture
No tabs. Marking up means comparing what you just did against the next thing.
Picks up where Screenshot stops
macOS takes the picture. Tamofy is everything after it.
Drag Out
Drag it into a message or a folder. A real file lands, not a promise of one.
Private by Design
No accounts, no tracking, no ads, nothing sent anywhere. Your pictures are stored locally on your Mac.
Getting a picture in
Four ways, and none of them involve leaving what you were doing.
- Drop a file on a window
- Drop a file on the menu bar icon
- Open a file, or Open With from Finder
- Paste whatever is on the clipboard
Capture a region with macOS's own screenshot shortcut, then bring it into a new window from anywhere - Tamofy doesn't need to be in front.
Marking it
Every tool is one key. No modifiers, no chords.
Arrow (A)
Point at what matters. Bend it around anything in the way.
Text (T)
Say it in words. Readable on any picture, at any angle.
Shape (S)
Box it, circle it, underline it. One key, four shapes - press again to cycle.
Draw (D)
Freehand, for what a shape won't say.
Highlight (H)
Make one line jump off the page. Marker stroke or straight band.
Number (N)
Turn a screenshot into steps. Drop pins 1, 2, 3 as you go.
Magnifier (M)
Show the detail without cropping the picture. Small differences become obvious.
Pixelate (P)
Blur what shouldn't leave the room - names, tokens, whole conversations.
Crop (C)
Cut to the point. Everything else stops competing for attention.
Style it
Colours and weight also a one key.
The palette (1-8)
Red, orange, yellow, green, blue, purple, white and black - in the order they sit on the palette.
Anything else (0)
Opens the colour picker.
Thickness ([ and ])
Steps down and up, without leaving the picture.
Adjust it
Tools need no modifiers - these three do. Hold one while you drag.
Constrain (⌃)
Angles snap, boxes square up, and a move locks to one axis.
Copy while dragging (⌥)
Drag out a duplicate and leave the original where it is.
Grab a mark (⌘)
Take hold of an existing mark while a pen is still in your hand.
Set up the way you work
Where the tools live, and which keys reach them.
Classic or Modern
Classic puts the tools in a rail down the left edge. Modern floats them in a bar over the foot of the picture. Settings › Editor switches between them, and sizes the Modern one.
Or neither (⌥⌘T)
Take the tools away in every window at once, when the picture wants the whole space. Nothing is lost - every key still works, and the pointer carries the tool it's holding, in the colour it will draw in.
Keys you choose
Re-record any tool, colour or thickness key in Settings › Editor, or clear it entirely - and the same goes for the three global shortcuts that reach Tamofy.
Getting it out
Send the PNG, keep the document.
Drag it out
Drag the picture straight out of the window into a message, a document, or a folder.
Clipboard
A PNG on the clipboard, ready to paste wherever you were typing.
Export image
A PNG in ~/Pictures/Tamofy. Export As… asks where instead.
Save document
A .tamofy document, which reopens with every mark still selectable and movable - so the arrow you put in the wrong place is a drag away, not a redraw.
When you close it by mistake
Closing a window isn't a decision you have to get right.
Bring back the last canvas
Picture, marks, position and zoom intact - and it still knows the file it came from.
Languages
English, German, Chinese and Japanese out of the box. Missing yours? Get in touch.
Try Tamofy
A free download on the Mac App Store.
Requirements
macOS 26 or later. Apple Silicon and Intel supported.
Where files go
One folder worth knowing about.
Pictures, and nothing more
Beyond the files you open, drop or paste, your ~Pictures folder is the only place Tamofy writes to.
A folder of its own
Documents are saved to ~/Pictures/Tamofy by default, and a picture you drag out lands in ~/Pictures/Tamofy/Drags.
Drags are filed by day, so you can always go back and find exactly what left the app, and when. Save As… and Export As… put things anywhere you like instead.
