# Simple Guetzli
A Guetzli compression helper
`go get github.com/romainmenke/simple-guetzli`
or download from the latest [release](https://github.com/romainmenke/simple-guetzli/releases).
This requires : [Guetzli](https://github.com/google/guetzli)
---
### Why?
Guetzli is cpu intensive and waiting for builds / compiles /... is something we all like to avoid.
This little tool keeps a log of compressed files and skips those that have already been done.
Now you can safely watch a folder with images and compress only that what needs to be done.
In short :
- compresses an entire folder at once
- executes compressions in parallel
- tracks what has been compressed
- determines file changes and recompresses
Useful :
- cancel at any time, finished compressions will not need to be redone.
- manage max threads.
- max memory is divided by number of Guetzli instances (so 1000mb ram with 4 threads will give 250mb ram for each)
- dontgrow flag deletes image files that got bigger because Geutzli failed to shrink them.
- copy flag to keep your input and output dirs in sync despite Guetzli errors or files that grew.

### Options
```
Flags:
--help Show context-sensitive help (also try --help-long and --help-man).
-q, --quality=95 Visual quality to aim for, expressed as a JPEG quality value. Default value is 95.
--log="info" Log level
-m, --memlimit=6000 Memory limit in MB. Guetzli will fail if unable to stay under the limit. Default limit is 6000
--nomemlimit Do not limit memory usage.
-f, --force Force recompression
--force-quality Force recompression if quality changed
-t, --threads=3 Max concurrent threads. Default limit is 3
-g, --dontgrow Delete compressed files that got bigger
-c, --copy Copy all files from source folder to output, without overwriting compression results
-v, --version Guetzli Version
Args:
[] Source directory
[] Output directory
[] Log directory, the log is used to prevent duplicate compressions
```
