Instagram Reels FAQ
Quick answers about formatting, privacy, and styling.
How do I make an Instagram Reel for free?
Upload your video to ToolDeck, select the 9:16 aspect ratio, generate auto-captions, and click Render. It is completely free and adds no watermark.
Do I need to log in to use this?
No. You do not need an Instagram account or a ToolDeck account. The tool is entirely open.
Will this tool add a watermark to my Reel?
No. Unlike CapCut, which sometimes adds a watermark to free exports, ToolDeck never stamps your video.
Is my video uploaded to a server?
No. The video processing (including AI captioning) runs 100% locally in your browser using WebCodecs and WebAssembly.
Can I convert a horizontal video to a Reel?
Yes. Select the 9:16 aspect ratio and drag the video to pan. The empty space is filled with a blurred background.
How do the auto-captions work?
We use OpenAI Whisper running locally in your browser. It listens to the audio and generates perfectly timed subtitles.
Are the auto-captions accurate?
Whisper is highly accurate for clear English. If there is background noise, use the "Edit text" tab to fix mistakes.
Can I edit the captions?
Yes. Click the "Edit text" tab in the left sidebar. You can rewrite any line of text.
Can I change the caption style?
Yes. We offer 45+ styles including Neon, Gradient, Vaporwave, Comic, and Classic. You can also change the text color and size.
What export resolution do you support?
We export 1080x1920 (Full HD). This is the exact resolution used by Instagram Reels.
What video formats are supported?
MP4, WebM, MOV, and MKV. We recommend MP4 (H.264) for the fastest rendering.
Can I use this on my phone?
It runs in mobile browsers, but we highly recommend desktop. Rendering a video and running the AI model uses a lot of memory.
Can I trim the video?
Yes. Use the timeline at the bottom to drag the teal handles and cut the start/end.
How long can my Reels be?
Instagram allows up to 90 seconds. We recommend keeping it under 30s for maximum viewer retention.
Does it keep the original audio?
Yes. The original audio is trimmed to match your clip and exported in the final MP4.
Why does rendering take a while?
Because everything happens on your device. It has to run the AI model, draw the captions on a canvas, and re-encode the video using your local CPU/GPU.
Is it really free?
Yes, 100% free. There are no hidden fees, no "Pro" version, and no watermarks.
Does it support 60fps?
The output is 30fps. This is the standard frame rate for Reels and keeps file sizes small.
What if I have a large file?
We recommend files under 1GB. If your file is larger, trim it first with our Video Trimmer.
Can I use this commercially?
Yes. You can use the output for client work, brand deals, or your own channel.
What if the browser crashes?
If you upload a very large video, the browser might run out of memory. Try trimming the video first.
Can I remove the captions?
Yes. If you do not generate captions, the video will render without them.
Does it work on Mac/Windows?
Yes. It works in any modern browser (Chrome, Edge, Firefox) on Windows, Mac, and Linux.
What are the best caption styles for Reels?
Neon Cyan and Comic are very popular because they pop on mobile screens and are easy to read.
Can I add emojis to the captions?
You can type emojis into the "Edit text" tab, and they will appear in the final video.
What works best for Reels
Here is how different types of footage perform when turned into a 9:16 Reel.
| Footage Type | Result | Notes |
|---|---|---|
| Talking head (vertical) | Perfect | Add auto-captions and a Neon style. This is the standard format for Reels. |
| Landscape 16:9 video | Perfect | Use the pan tool to track the subject. The empty space is filled with a blurred background. |
| Action / Sports video | Works, with caveats | Manual panning is required. You may need to render a few times to get the perfect tracking. |
| Multiple speakers | Works, with caveats | Whisper AI transcribes everyone, but does not label who is speaking. |
| Long videos (>60s) | Works, with caveats | Instagram Reels supports up to 90s, but we recommend 15-30s. Trim the clip first. |
| Complex multi-track editing | Poor | If you need green screens and 10 layers, use CapCut or Premiere. |
Tips for viral Reels
Check for AI hallucinations
Whisper AI sometimes invents words during long silences. Use the "Edit text" tab to delete them.
Use bold captions
Reels move fast. Use the "Neon" or "Comic" styles for maximum readability.
Avoid the bottom UI
Instagram puts the caption and buttons at the bottom. Drag your text to the middle or top.
Test the pan
Hit "Play" in the preview to see if your subject stays in frame before rendering the whole video.
ToolDeck vs CapCut for Reels
CapCut requires an account and uploads your video to the cloud. ToolDeck is entirely local and free.
| Feature | TToolDeck | CapCut |
|---|---|---|
| Uploads video to a server | No | Yes |
| Adds a watermark to export | No | Yes |
| Requires an Instagram login | No | Yes |
| Free auto-captions included | Yes | No |
| Manual pan & zoom tracking | Yes | Yes |
| 45+ caption styles | Yes | Yes |
| Subscription for Pro features | No | Yes |
| Works offline | Yes | No |
| Browser-based (no install) | Yes | No |
