sticker-convert

• A python script for creating, downloading, converting+compressing and uploading stickers from multiple instant messaging applications.
• With GUI and CLI that runs on Windows, MacOS and Linux
• Currently supports Signal, Telegram, WhatsApp (Create .wastickers), Line (Download only), Kakao (Download only), Viber, Discord (Download only), iMessage (Create Xcode sticker pack project)
• Supports static and animated stickers, with transparency support

Downloads

• Pre-compiled releases for Windows, MacOS and Linux (As AppImage).
  • Windows: Unzip the downloaded file and run sticker-convert.exe
  • MacOS: Unzip the downloaded file, hold control and open hold_control_and_click_open_me.command for the first time, then sticker-convert.app in the future
  • Linux: chmod +x the downloaded AppImage and run it
• pip package: pip install sticker-convert. Launch with sticker-convert or python -m sticker_convert
• Docker image for running on Linux.
• Try in Google Colab without downloading (Requires Google account), which runs the code on Google server and get the result from Google Drive. However, it maybe slower than running on your computer. (~15 seconds per file if not converting to .apng, ~1 minute per file if you convert to .apng)

sticker-convert --export-telegram --export-signal

Convert local files to a custom format

sticker-convert --fps-min 3 --fps-max 30 --quality-min 30 --quality-max 90 --res-min 512 --res-max 512 --steps 10 --vid-size-max 500000 --img-size-max 500000 --vid-format .apng --img-format .png

Tip: Use the CLI for converting multiple stickers all at once without intervention!

The following example converts two Line sticker packs into Signal, Telegram and WhatsApp all at once

sticker-convert --no-confirm --download-auto https://store.line.me/stickershop/product/1/en --export-signal
sticker-convert --no-confirm --export-telegram
sticker-convert --no-confirm --export-whatsapp

sticker-convert --no-confirm --download-line https://store.line.me/stickershop/product/2/en --preset signal --export-signal
sticker-convert --no-confirm --preset telegram --export-telegram
sticker-convert --no-confirm --preset whatsapp --export-whatsapp

Note that you can see the conversion result in export-result.txt

Running (GUI)

docker run -d -it --name sticker-convert \
    -v /path/to/your/stickers_input:/app/stickers_input \
    -v /path/to/your/stickers_output:/app/stickers_output \
    -p 5800:5800 \ # Port for Web UI
    -p 5900:5900 \ # Optional for VNC
    laggykiller/sticker-convert:latest

Running (CLI)

docker run -d -it --name sticker-convert \
    -v /path/to/your/stickers_input:/app/stickers_input \
    -v /path/to/your/stickers_output:/app/stickers_output \
    laggykiller/sticker-convert:latest \
    python3 /app/sticker-convert.py --help

Alternative: Use docker-compose.yml

docker compose up

Building

docker build --tag sticker-convert:latest --target full .
docker build --tag sticker-convert:latest-min-cli --target min-cli .

Conversion is slow

Try the following tips:

• Increase number of processes (--processes)
  • Increasing over default value can actually be slower though
• Decrease number of steps (--steps)
  • Decreasing too much can result in poor quality though

Running out of RAM / System frozen

Try to decrease number of processes (--processes)

MacOS complains that program from unidentified developer

To become an identified developer, I have to pay USD$99 to Apple every year.

There are two ways to bypass this problem:

1. Permanent: Open terminal and execute sudo spctl --master-disable before running sticker-convert.
2. Temporary: Open terminal and execute xattr -d com.apple.quarantine ./Downloads/sticker-convert-macos.zip before extracting the downloaded zip file.

If macOS still complains about individual binaries (e.g. apngasm), go to System Preferences > Security & Privacy and press Open Anyway for each file.

I want to upload stickers that are in stickers_output that have not been uploaded yet

CLI: Run with --no-compress --export-xxxxx

GUI: Select From local directory for Input source, tick No compression box and select Upload to xxxxx for Output options

Where are credentials stored?

Credentials are stored in creds.json

By default, it should be in the same directory you run the program.

However, if the directory is not writable (e.g. Installed it to /Applications in macOS, or /usr/local/bin in Linux), then creds.json is stored in...

• Windows: %APPDATA%/sticker-convert/creds.json
• Other: ~/.config/sticker-convert/creds.json

What does "power" and "steps" mean?

It's actually a bisection method to look for most optimal compression setting. The power provides a way to make the values 'deviate' to one side (Negative power would cause sticker-convert to try more large values; Power set to 1 would cause sticker-convert to distribute it's trial evenly between the min and max values; Power more than 1 would cause sticker-convert to try more small values)

To illustrate, let's look at what --steps 16 --fps-min 5 --fps-max 30 --fps-power 3.0 does.

1. We would start from 8/16 (step 8 out of 16 steps), which is the mid-point.
2. We would calculate a factor using power: (8/16)^3.0 = 0.125
3. The fps setting is round((max - min) * step / steps * factor + min), which is round((16-1) * 8 / 16 * 0.125 + 5) = round(5.9375) = 6. This means fps would be set to 6.
4. If the file size is too small, then we would try 4/16 (step 4 out of 16 steps, which is midpoint of 0 to 8.). Else, we would try 10/16 (step 10 out of 16 steps, which is midpoint of 8 to 16).
5. Repeat 1-3.
