Show exactly what you mean.

Snix is a screenshot app for the Mac. Capture any part of your screen, point at what matters with arrows, text and mosaic, then drag the result straight into a message.

Download on the Mac App Store

For macOS 15 or later. English, 简体中文, 한국어.

Every way to grab the screen.

The first four shortcuts work from any app and can be changed in Settings; the last two work while Snix is in front. Captures keep every Retina pixel.

Capture modes and their default shortcuts
CaptureShortcutWhat you get
Region⌃⌘5Drag a frame, then fine-tune it with eight handles or type an exact width and height. Press Space to pick a window instead.
Full screen⌃⌘6With more than one display, every screen shows its name and size; click the one you want.
Window⌃⌘WOne window, cut cleanly from whatever sits behind it.
Last region⌃⌥⌘5The same frame again, for a before and after.
Menu⇧⌘UFrom the menu bar icon or the Capture menu: a countdown while you open the menu, then just the menu and its title.
Timed⌃⇧⌘5A region after a countdown, for hover states and tooltips that vanish on a click.
A region being selected in Snix: a frame with eight handles, its size as 1280 × 720 px and 640 × 360 pt, and fields to type an exact width and height
Prefer ⇧⌘3, ⇧⌘4 and ⇧⌘5? Snix offers to take them over on first launch.

Mosaic it before you send.

Drag over anything private and choose how it disappears. When you export, drag or share, the cover is painted into the pixels, so what was under it never leaves your Mac. Try it: drag across the message.

Features

Copy text out of any screenshot.

Drag across the words and press ⌘C. Text is read by Apple’s Vision on this Mac; nothing is uploaded.

Hand back PDFs others can still edit.

Markup goes out as standard PDF annotations that Preview and Acrobat can move, change or delete.

Put a summary of every note up front.

A page-by-page list before the document, each entry linked to its place. A4 or US Letter, by your region.

Count down before grabbing a menu.

A card in the middle of the screen counts the seconds, and it never shows up in the shot.

First, frame what matters.

Drag the file icon out, or export it as

  • PNG
  • JPEG
  • HEIC
  • WebP
  • TIFF
  • GIF
  • BMP
  • PDF

Up to 77% smaller

JPEGs that look the same and weigh far less.

Every JPEG Snix writes goes through Jpix, our own optimizer. It retunes the compression block by block for what your eye can actually see, so the picture looks almost identical to the original while the file shrinks by up to 77% in our tests.

It is not just for screenshots. Open a photo you already have, export it as JPEG, and keep the lighter copy for email, the web or your archive. For images with transparency, choose WebP: it keeps the clear areas and lands at about half the size of a JPEG.

Your Skitch files still open.

Snix reads images saved by Skitch 2.9 and turns their arrows, text and shapes back into things you can move and change.

  • Open the file like any image: double-click, drag it in, or ⌘O.
  • Keep going and save as a .snix project; the original is never touched.
  • Anything Snix can’t rebuild opens as the flat picture Skitch drew, and Snix tells you so.

Every page of the PDF.

Drop a PDF on Snix and the same tools work on every page. Swipe or scroll to turn pages; zoomed in, you read to the edge first.

  • Pages you leave alone keep their vector text, still sharp and searchable.
  • The markup list, ⇧⌘L, shows every note by page; click one to jump to it.
  • Export only the pages you marked, with a summary of every note up front.
  • Cropped or covered pages are flattened, so the hidden text can’t come back.

Questions, answered.

No. Captures, projects and text recognition all stay on your Mac. Snix has no account and no upload service of its own; a file only leaves when you drag, export or share it.

Press the keys you know.

Get Snix from the Mac App Store. On first launch it offers your familiar shortcuts, and every capture opens straight in the editor.
