Auto
Sets how the video is encoded. "Auto" suits most conversions. "Copy" reuses the video as-is, so it is fast and keeps full quality, but only when the output format supports it.
No change
Choose how the video is resized: to a set resolution, or to a different aspect ratio, where the video's width is kept and the height is recalculated to match. Select "No change" to keep the original size.
No change
Sets how many frames per second the output video has. Lowering it reduces file size but makes motion less smooth, and raising it above the source frame rate won't add smoothness. "No change" keeps the source frame rate.
None
Rotates the video clockwise by the angle you select. Choose "None" to leave it as-is.
No change
Flips the video horizontally or vertically. "No change" leaves it as-is.
Upload
Select the best option for your subtitles: 'Upload' to add your own, or 'Copy' to replicate from the original file.
Choose a file Browse
Upload a .srt or .ass file.
Hard
Choose how subtitles are added. "Hard" burns them into the video permanently; "Soft" keeps them separate so viewers can turn them off. Default is Hard.
Auto
Sets how the audio is encoded. "Auto" suits most conversions. "Copy" reuses the audio as-is, so it is fast and keeps full quality, but only when the output format supports it.
100% represents the original volume. To double the volume, increase it to 200%. To reduce volume by half, select 50%
Fades the audio in at the start of the output.
Fades the audio out at the end of the output.

How to Convert SWF to Kindle Video?

  1. Click the “Choose Files” button to select your SWF files.
  2. Click the “Convert to Kindle Video” button to start the conversion.
  3. When the status change to “Done” click the “Download Kindle Video” button

Easy to Use

Simply upload your SWF files and click the convert button. You can also batch convert SWF to Kindle Video format.

Best Quality

We use both open source and custom software to make sure our conversions are of the highest quality. In most cases, you can fine-tune conversion parameters using “Advanced Settings” (optional, look for the icon).

Free & Secure

Our SWF to Kindle Video Converter is free and works on any web browser. We guarantee file security and privacy. Files are protected with 256-bit SSL encryption and automatically deleted after 8 hours.


Shockwave Flash, later renamed Small Web Format (SWF), is the file type Adobe Flash used to deliver animations, interactive banners, browser games, and video across the web. An SWF stores vector artwork, timelines, embedded media, and ActionScript code in a compact package that streamed well over slow connections. Adobe ended support for Flash Player on 31 December 2020, and every major browser has since removed it, so SWF is now a legacy format.

 

How to open an SWF file?

Ruffle is the modern route: it is a Flash emulator that runs SWF content as a desktop application or browser extension, without Flash Player itself.

 

Standalone players such as SWF File Player also work on Windows, and VLC media player can play simple SWF files that contain only video. For animations you want to keep long-term, converting them to a standard video format with our SWF to MP4 tool is the most reliable way to preserve them.

Kindle Video is an MP4 file encoded for Amazon’s Fire tablets and Kindle Fire devices, using H.264 video with AAC audio. The settings are chosen to match the screen size and decoding capability of these tablets, so personal videos play back smoothly without the device having to re-encode them. Note that e-ink Kindle e-readers cannot play video at all — only the Fire tablet line can.

 

How to open a Kindle Video file?

Connect the tablet to your computer with a USB cable, copy the file into the Movies or Videos folder, then open it from the device’s Videos or Gallery app.

 

You can also send the file to the tablet through a cloud storage service such as Dropbox, Google Drive, or OneDrive. (Amazon Cloud Drive, once the obvious choice here, was discontinued in December 2023.) The same MP4 plays normally on any desktop computer too.
