How to Edit Stickers | Three Workflows, One Complete Guide

Sticker editing covers three distinct tasks — editing photo-based stickers on iPhone, adjusting stickers inside video apps like Magisto, and preparing print-ready sticker artwork for platforms like Redbubble.

One wrong tap and the sticker menu disappears, or the transparent background renders as white, or the animation simply won’t play. The fix depends on which kind of sticker you’re editing. Apple’s iPhone now has its own sticker creator built into Photos. Video-editing apps like Magisto let you adjust stickers scene by scene. And if you’re designing stickers for production or sale, the rules shift entirely — resolution, format, and spacing all matter. This guide covers all three.

Editing Stickers on iPhone (iOS 17+)

Apple’s built-in sticker maker lives in the Photos app and handles one specific task: lifting a subject from a photo and turning it into a sticker with effects. It’s not a full image editor — you can’t draw on the sticker or change its colors there — but the results save directly to your iPhone’s sticker menu.

How to Create and Edit a Sticker on iPhone

1. Open Photos on your iPhone.
2. Tap a photo to view it full screen, then touch and hold the main subject until it lifts from the background and a glow appears.
3. Release your finger, then tap Add Sticker.
4. To apply an effect, tap Add Effect and choose between Outline, Comic, or Puffy. Each effect previews in real time — tap one to apply it.
5. Close the sticker menu. The new sticker now lives in your iPhone’s sticker drawer, accessible from the onscreen keyboard or Markup tools.

The sticker appears in the sticker menu with the effect you selected. If you don’t see the effects, make sure you tapped the sticker itself before tapping Add Effect.

Apple also supports Live Photos — touch and hold the subject of a Live Photo, and the resulting sticker will animate. This works the same way as the still-photo method above.

How to Delete an iPhone Sticker

Open the original photo in Photos, tap the relevant controls near the sticker, then touch and hold the sticker and tap Remove. The sticker disappears from your sticker menu immediately.

Editing Stickers Inside a Video (Magisto iOS)

If the sticker lives inside a video you’re editing in Magisto, the controls are different. You’re not creating a new sticker — you’re repositioning, animating, or adjusting an existing one on a specific scene.

1. Open the video you want to edit in Magisto.
2. Tap Edit at the bottom left corner of the screen.
3. Scroll through the scenes or tap the stack icon to view the storyboard and pick the scene containing the sticker.
4. Tap the sticker itself. The editing controls appear around it.

From here, Magisto offers four adjustment categories:

• Animate — Choose None, Fade, Stamp, or Pop to set how the sticker enters the scene.
• Edit — Move the sticker forward or backward in the layer stack, copy it to another scene, duplicate it, or delete it.
• Opacity — Drag the slider to make the sticker more or less transparent.
• Adjust — Flip the sticker horizontally or vertically, scale it larger or smaller, or rotate it to any angle.

All changes save automatically when you exit the sticker-editing mode.

Preparing Sticker Artwork for Print (Redbubble Production)

Designing stickers for sale or print requires meeting platform-specific specs long before any editing happens. These rules apply at the file-preparation stage — edit the artwork in Photoshop, Illustrator, or a similar tool, then upload the correct file.

Common Redbubble Sticker Mistakes

• Uploading without a transparent background. A JPEG or a PNG with a white background will print with a white rectangle around the design — exactly what the transparent requirement is meant to prevent.
• Skipping the 2800-pixel recommendation. Smaller files might preview fine but will look soft or blurry at the larger sticker sizes.
• Packing artwork too tightly. Cramming multiple designs into one file without the 0.7 cm gap leads to miscuts or partial cuts.
• Ignoring stray pixels. A single rogue dot at the edge of a design becomes a visible nub on the printed sticker.

Fix all four in your image editor before uploading. Redbubble won’t edit or fix files for you.

Editing Sticker Packs for Messaging Apps (Signal)

Messaging platforms have their own sticker rules. Signal, for example, lets you create custom sticker packs in Signal Desktop but imposes strict constraints:

• Non-animated stickers: PNG or WebP.
• Animated stickers: APNG format required.
• Each sticker: capped at 300KB.
• Per pack: up to 200 stickers.
• No editing after upload. Once a pack is published, you cannot modify it — you can only delete the whole pack and start over.

Note: GIPHY stickers require different specs — GIF source files only, must include movement, must have transparency, and GIPHY does not support APNG. Always check the platform’s current requirements before preparing files.

Final Checklist: Editing Stickers by Platform

Before exporting or uploading any sticker project, confirm the format against the destination:

• iPhone sticker: Created from a photo subject in Photos; effects applied after the sticker is made. No external file needed.
• Magisto video sticker: Adjust animation, opacity, position, and flip within the app’s scene editor.
• Redbubble sticker artwork: 2800×2800 PNG with transparency, 0.7 cm spacing, no stray pixels.
• Signal sticker pack: PNG/WebP (static) or APNG (animated), 300KB max per sticker, 200 per pack — no post-upload edits.
• GIPHY sticker: GIF with transparency and movement; no APNG.

Match the file to the platform’s rules, and the sticker will work exactly as intended.
