How to convert SWF to AMR:
1. Click the "Choose Files" button to select multiple files from your local device, or click the "URL" button to choose an online file. The source file can also be in video format. Video or audio file size can be up to 200MB. You can use the file analyzer to view the source audio's detailed information, such as track name, genre, bitrate, and sampling rate.
2. Set the target audio format, bitrate, and sample rate. The target audio format can be WAV, WMA, MP3, OGG, AAC, AU, FLAC, M4A, MKA, AIFF, OPUS, or RA.
3. Click the "Convert Now!" button to start batch conversion. It will automatically retry conversion on another server if one fails; please be patient while converting. The output files will be listed in the "Conversion Results" section. Click the icon to show the file QR code or save the file to cloud storage services such as Google Drive, OneDrive, or Dropbox.
SWF vs AMR:
| Name | SWF | AMR |
| Full name | Small Web Format | Adaptive Multi-Rate |

| MIME | application/vnd.adobe.flash-movie | audio/amr |
| Developed by | Adobe Systems | 3GPP |
| Type of format | Vector graphic animation | Audio compression format |
| Introduction | SWF is an Adobe Flash file format used for multimedia, vector graphics and ActionScript. Originating with FutureWave Software, then transferred to Macromedia, and then coming under the control of Adobe, SWF files can contain animations or applets of varying degrees of interactivity and function. They may also occur in programs, commonly browser games, using ActionScript. | The Adaptive Multi-Rate (AMR or AMR-NB or GSM-AMR) audio codec is an audio compression format optimized for speech coding. AMR was adopted as the standard speech codec by 3GPP in October 1999 and is now widely used in GSM and UMTS. |
| Technical details | Programmers can generate SWF files from within several Adobe products, including Flash, Flash Builder (an IDE), Adobe Animate (the replacement for Adobe Flash as of Feb. 2016), and After Effects, as well as through MXMLC, a command-line application compiler which forms part of the freely-available Flex SDK. | AMR speech codec consists of a multi-rate narrowband speech codec that encodes narrowband (200-3400 Hz) signals at variable bit rates ranging from 4.75 to 12.2 kbit/s with toll quality speech starting at 7.4 kbit/s. Sampling frequency 8 kHz/13-bit (160 samples for 20 ms frames), filtered to 200-3400 Hz. |
