Device Frame Mockups Without Figma

Device frame mockup online should mean: pick hardware, drop PNG, adjust scale, download. ToolComb's Device Frame Mockup follows that script in the browser. For when to open it versus other presentation tools, see Best free screenshot and mockup tools.

When a frame beats a flat screenshot

Use a device frame when:

• The landing page hero sells a mobile app, not a web dashboard.
• A pitch deck needs hardware context without a photo shoot.
• An App Store or Play listing wants a recognizable silhouette (check store guidelines - frames are marketing assets, not substitutes for required raw captures).

Skip the frame when:

• The audience is developers reading an API changelog - Screenshot Beautifier padding is enough.
• The capture is desktop-only and framing it in a phone lies about the product.

Prepare the screenshot

Match orientation - portrait UI in a portrait frame. Landscape dashboards in phone frames require scale so small that text dies.

Include or exclude the status bar consistently across a set. Mixed bars look like sloppy compositing.

Export at native or 2× resolution from the simulator or device. Simulator Cmd+S on macOS is cleaner than photographing a phone on a desk.

Redact notifications and personal messages in the status bar area before framing.

Workflow in the mockup tool

Open Device Frame Mockup.

1. Choose a device silhouette that matches the story (modern phone vs tablet).
2. Upload PNG or JPG/WebP the browser can decode.
3. Scale and position the screenshot inside the screen mask until corners align and critical UI clears the notch/bezel if present.
4. Set background - solid brand color or subtle gradient behind the hardware.
5. Download PNG for slides, Webflow, or email to agencies.

Rendering stays local. You are not waiting on a server queue or recovering a download link from email.

Common fixes

Black bars inside the screen - aspect ratio fight. Re-capture at the frame's aspect or accept letterboxing with a intentional background color, not accidental gray bars.

Blurry text - screenshot scaled up too far. Start from a higher-resolution capture.

Notch covers your header - move the screenshot down or pick a frame without a dynamic island if the product demo requires top navigation visible.

Huge file size - a 3000×3000 export from a retina sim is fine for print; for web heroes, resize or compress after export.

Chain with beautifier and compress

Real launches rarely stop at one tool:

• Docs path - Beautify screenshots for README, frame for marketing site.
• Weight path - frame → Online Image Compressor if Lighthouse complains about the hero.

Do not compress the raw sim capture, frame it, then compress again at quality 40 unless you checked text at 100% zoom.

Figma vs browser mockup: honest split

Need	Browser frame	Figma
One PNG for a launch email	✓	Overkill
Twelve localized frames with shared components	Slow	✓
Animated device video	✗	After Effects / dedicated tools
Exact brand bezel color match	Approximate	✓ with design system

ToolComb is not replacing your design org. It is replacing "sign up to export one PNG" for a solo dev or PM.

Privacy

Framing does not require uploading the screenshot to ToolComb's app server. Your unreleased UI stays on disk until you send the export to Slack or a CMS. Cloud mockup libraries that store projects on their drive are a different risk model - choose based on confidentiality, not convenience alone.

Pick the frame, align once, export, and get back to shipping the app inside the bezel.
