Frequently Asked Questions
Is my video uploaded anywhere?+
No. Your video is loaded as a local blob and processed entirely in your browser. Nothing is uploaded to any server. You can verify by disconnecting from the internet after the page loads — the tool keeps working.
Which video formats are supported?+
Anything your browser can play in a video element. MP4 (H.264) and WebM are universally supported. MOV files usually work in Safari and Chrome on macOS. If a file doesn't play, try re-encoding it as MP4.
What sizes can I export?+
YouTube 16:9 at 1280×720, TikTok 9:16 at 1080×1920, and Instagram 1:1 at 1080×1080. These are the official recommended sizes for each platform.
Should I use PNG or JPG?+
JPG produces smaller files and is what YouTube/Instagram convert to internally. Use PNG for sharper text edges or transparent test exports, and JPG for the final upload — quality 90+ is visually indistinguishable on photographic content.
Can I add multiple lines of text?+
Yes. The title line wraps automatically when it would overflow the safe area. You can also add a second subtitle line below the title for context.
Why is my exported text smaller than the preview?+
The preview shows the actual export pixel size scaled to fit the page. The exported file is 1280×720 (or larger for TikTok/Instagram), so what you see is exactly what you get when uploaded at full resolution.
Tips for High-CTR Thumbnails
- 1. Pick a frame with an emotion or motion — neutral faces underperform.
- 2. Keep the title under 5 words. Mobile previews are tiny.
- 3. Use high contrast: white text + 20-30% tint usually wins over color-on-color.
- 4. Test 2-3 variants. Even tiny color shifts can change click-through significantly.
