Frequently Asked Questions & In-Depth Answers

Is SimpleDeck completely free for commercial and business use?: Yes, SimpleDeck is 100% free forever for personal creators, commercial agencies, corporate marketing, advertising, and e-commerce. All 22 bundled fonts carry open commercial licenses (SIL OFL / Apache License), and every exported slide is completely watermark-free.
Do I need to create an account, sign in, or enter a credit card?: No account or payment details are ever required. There are zero paywalls, mandatory logins, or verification steps. You can start designing and exporting slides immediately upon visiting the website.
What is the recommended Instagram carousel dimension and aspect ratio for 2026?: The most effective dimension for Instagram is 4:5 Portrait at 1080 x 1350 pixels. Compared to a 1:1 square, the 4:5 format takes up 33% more vertical space on mobile smartphone screens, drastically reducing feed scroll-past rates.
When should I use 1:1 Square versus 4:5 Portrait format?: Use 4:5 Portrait when designing exclusively for the Instagram mobile feed to maximize screen dominance and dwell time. Use 1:1 Square (1080 x 1080 px) if you plan to cross-post the exact same carousel slides across LinkedIn, Facebook, and blog thumbnails.
How do I create a seamless 'Continuous Panorama Carousel' with connected slides?: Enable the 'Carousel Guidelines' toggle in the studio canvas toolbar. This displays vertical boundary guides showing where slide 1 transitions into slide 2. Position images, graphics, or arrows across this guide line to produce a continuous swipe effect without Photoshop.
Are my uploaded photos and text stored on your servers or at risk of leaks?: No, never. SimpleDeck runs entirely client-side in your browser using the HTML5 Canvas API. Your uploaded pictures, brand logos, and written text are never sent to or stored on any external server. Everything remains 100% private on your own device.
Can I download all carousel slides at once instead of saving them one by one?: Yes! Click the 'Save All as ZIP' button in the top navigation bar. SimpleDeck will automatically render all slides into high-resolution PNG images and package them into a single, organized ZIP file in 1-2 seconds.
Can I generate Threads quotes and X (Twitter) mockup cards with SimpleDeck?: Yes. From the left sidebar widget panel, select 'Threads Quote Card' or 'X (Twitter) Card' to generate aesthetic social mockups complete with profile avatars, verified badges, handles, and timestamps in one click.
Will I lose my work if I accidentally close the tab or refresh the browser?: No. SimpleDeck features real-time LocalStorage auto-save. Your slide deck layout, custom text, and color settings are continuously cached in your browser. Reopening the tab restores your previous session automatically.
Can I use SimpleDeck on mobile smartphones and tablets (iPad)?: Yes! SimpleDeck is built with responsive web architecture, allowing you to edit and preview your card news smoothly on mobile Safari, Chrome, and tablets without installing any app.
