1. Install Snap Markup
Snap Markup is a universal app for iPhone and iPad. Download it from the Apple App Store. Android users can grab the free version on Google Play.
The app requests Photos permission on first launch — that's how it reads images you pick and saves your edits back to the gallery. No account, no login, no setup wizard.
2. Open a photo
From the Home tab you have several entry points:
- Photo grid — tap any thumbnail to start editing. Tap the ⓘ in the corner to see EXIF info first.
- Floating action button (+) — tap to open Empty canvas, Web capture, Map capture, Camera, Collage, Photo picker, or Generate PDF flow.
- Search — find a specific photo by date or album.
3. Pick an editing tool
The bottom toolbar shows up to 16 tools. Tap any tool to enter that mode; the canvas swaps to that tool's controls.
- Draw — pen, marker, highlighter, arrows, rectangles, circles
- Text — captions and labels with custom fonts, color, alignment, shadow, stroke
- Sticker — emoji and SF-symbol stickers
- Crop — free, square, or preset aspect ratios + smart auto-crop suggestion
- Spotlight — dim everything outside a region
- Mosaic — pixel-blur sensitive areas; adjust brush size and density
- Photo Sticker — drop another photo on top, adjust opacity, mask the background
- Filter — curated filters with strength control
- Steps — drop numbered callouts; toggle connector arrows for walkthroughs
- Rotate — 90° spins or freeform
- Adjust — auto-enhance plus manual exposure / contrast / saturation / warmth / shadows / highlights
- Background — Vision-powered foreground mask; blur or replace the background, or auto-pixelate every face
- Stamp — burn the photo's date and GPS-resolved address into the corner
- Measurement — drop a calibrated ruler
- Bubble — 10 comic-style speech callouts with size and rotation sliders
Settings → Edit → Tool Order lets you reorder the toolbar and toggle individual tools on or off.
4. Layer your annotations
Every annotation is a tappable, draggable layer. Tap to select; drag to move; pinch to scale; rotate with two fingers. Tap the × on a selected layer to delete it. The editor supports unlimited undo / redo within the session.
5. Save or share
When you're done, tap Done to commit the session, then choose:
- Save — exports to your Photo gallery as PNG or JPG (Settings → Edit → Image File Format / Quality).
- Share — opens the iOS share sheet for Mail, Messages, AirDrop, social apps, Files, Copy.
- Print — sends to AirPrint with paper size and orientation.
6. Build a multi-photo PDF
From Home, tap the floating + button and pick Generate PDF. Select multiple photos from the picker, then arrange and rotate them as pages on the next screen. Tap Generate to open the PDF Options sheet, where you can:
- Name the PDF
- Pick image quality (Low / Medium / High)
- Pick orientation (Portrait / Landscape)
- Pick output type (PDF or Image bundle)
- Toggle password protection and reveal the password with the eye icon
Preview the result with Apple's Quick Look, then close to land back on Home.
7. Web & map capture
Tap the + floating button → Web to load any URL, scroll the full page, and grab a tall screenshot ready to mark up. Map works the same way for Apple Maps content.
8. View photo info (EXIF)
Tap the ⓘ button on the bottom-right corner of any thumbnail in the Home photo grid to open an iOS-Photos-style metadata popover. You'll see capture date, dimensions, file size, format, camera make & model, lens, exposure (aperture / shutter / ISO / focal length), and a map of the photo's location.
9. Adjust settings
Settings → General lets you toggle Smart Crop, Landscape Mode, Auto-save to gallery, and the Help Tips overlay. Settings → Edit changes Theme (Auto / Light / Dark), Language, Tool Order, and image export size / format / quality. Settings → Help & Support has the in-app tutorial video, share, rate, feedback, privacy policy, and version info.
