Download and installation

These instructions are only for the Mac version of ImageOptim. See version for your system.

Download ImageOptim archive — it should download within seconds.
Open the downloaded archive (double-click the ImageOptim.tbz2 file after it finishes downloading) — it will reveal ImageOptim.app.
Then drag the ImageOptim.app icon to Applications, and open it from there.

Usage

After launching ImageOptim.app, drag’n’drop images into its window (if drag’n’drop is not convenient for you, you can press the [+] button in the bottom-left corner instead).

Files are saved automatically. There are no new files generated — the files you drop are optimized in-place.

ImageOptim overwrites the files with their optimized versions. This is safe, because ImageOptim preserves image quality. If you’re not comfortable with that, you can create copies of the files before dropping them into ImageOptim. Also, as a precaution, ImageOptim puts original files in the Trash, so you can easly restore them if you ever need to.

Depending on the number and sizes of the files it can take a few seconds or even minutes to process them.

Icons next to the file show optimisation status:

	= working, please wait (if it takes too long, you can select the file and choose menu File › Stop ).
	= the file is optimal already, so it hasn’t been changed. That’s normal if you’ve run ImageOptim on this file before.
	= Success! The file has been optimized and saved.

Note that optimizations apply to a particular file. If you change the optimized file (e.g. edit the image or resize it) then you’ll need to optimize it again.

Preserving metadata (EXIF, GPS info) and color profiles

By default ImageOptim removes invisible metadata from images, such as EXIF camera information and color profile.

If you want to keep digital camera information (such as GPS position or exposure), or you’d like to keep color profles (to prevent slight shift in color brightness or saturation if images come from an unusual device), or you want to keep authorship information you’ve embedded in the files, then in Preferences disable stripping of metadata:

Metadata makes files larger. If you’re publishing images on the Web, it’s best to remove all metadata, because browsers either don’t make use of it, or support it poorly.

Currently, ImageOptim doesn’t have option to only remove some types of metadata — it’s all or nothing.

ImageOptim for various platforms

Linux

Trimage (GUI) — similar to ImageOptim and uses many of the same lossless tools under the hood.
ImageOptim Web Service (HTTP API) — resize and optimize images in your web applications.
Online interface — a JPEG compressor that produces smaller, higher quality files. The web interface works with any system.

Command-line

With these tools and a bit of a glue code you can build your own image optimizer:

pngquant — lossy PNG compressor.
Zopfli, PNGOUT — the most efficient lossless PNG compressors.
AdvPNG — a PNG compressor with a decent speed.
MozJPEG — includes lossless jpegtran .
Lossy Gifsicle — a fork of Gifsicle with heavier compression.

Windows

The ImageOptim app only works on Macs (sorry!), but you can achieve similar compression with some other tools:

Online interface — a JPEG compressor that produces smaller, higher quality files. The web interface works with any system.
Pinga — closed source, but similar to ImageOptim.
FileOptimizer (Download) — supports many file formats, and it’s Free and Open Source.
pngquant — lossy PNG compressor. It has some Windows-compatible GUI apps and Photoshop plug-ins available.

Older Mac OS X

If you use a Mac that is more than 6 years old, or haven’t updated OS X in the last couple of years, you’ll need an older version of ImageOptim:

ImageOptim for Mac OS X 10.6 (Snow Leopard, 2009). Works on 64-bit Intel Macs only.
ImageOptim for Mac OS X 10.5 (Leopard, 2007). Universal app that supports 32-bit Intel, and PowerPC.
ImageOptim for Mac OS X 10.4 (Tiger, 2005).
All other Mac versions

Requires macOS 10.9+. Works with Big Sur. It’s Free and Open Source. Donate.

Faster web pages and apps

Reduces image file sizes — so they take up less disk space and download faster — by applying advanced compression that preserves quality.

Image files scrubbed clean

Best tools with drag’n’drop

Seamlessly combines all the best image optimization tools: MozJPEG, pngquant, Pngcrush, 7zip, SVGO and Google Zopfli. All Free and Open-Source.

“The app works efficiently, it’s brain-dead simple to use, and it does just what it promises” — MacWorld

“Basically, ImageOptim works like magic, cutting down the size of images without making them look worse” — MacStories

Version 1.8.8
macOS 10.9+
Compatible with macOS Big Sur

ImageOptim is excellent for publishing images on the web (easily shrinks images “Saved for Web” in Photoshop). It’s useful for making Mac and iPhone/iPad applications smaller (if you configure Xcode to allow better optimization).

How does it work?

When you drag’n’drop images into ImageOptim’s window it will run several image optimization tools automatically and combine their results, ensuring that you always get the smallest file.

A special option for even smaller files

If you enable Lossy minification you’ll get smallest file sizes possible.

By default ImageOptim is very cautious and exactly preserves image quality, but if you allow it to change the quality — even only a little — it will be free to use much more aggressive optimizations that give the biggest results. You can configure lossy optimizations in ImageOptim’s Preferences . ImageOptim can apply lossy compression not only to JPEG , but SVG , anim GIF and PNG as well!

Open Source

ImageOptim is free, open-source software under terms of the GPL v2 or later. You can fork the code on GitHub and improve it! Feel free to contact me for assistance.

Frequent answers

You can get the same or better compression if you enable Lossy minification option in in ImageOptim preferences.

Tools like ImageAlpha/pngquant/TinyPNG /JPEGMini/MozJPEG make files smaller by using lossy compression which lowers image quality, which ImageOptim doesn’t do by default, but can if you allow it.

Can I keep embedded copyright, camera information?

Yes. Uncheck Strip JPEG metadata in Preferences. It’s slow on PNG files. How can I make it faster?

In preferences uncheck PNGOUT and Zopfli . Without these tools optimization will run much quicker, but will be a bit less effective. Will ImageOptim be in the App Store?

No, and please beware of knock-offs in the App Store! Apple’s has been selling three already.

ImageOptim is given for free on terms that basically say “you can do whatever you want except taking this freedom away from others”. Apple does not allow such permissive terms. Apple requires all App Store users to accept DRM (copy protection) and legal restrictions in the iTunes EULA .

ImageOptim (mac), smush.it — сжимаем изображения

Наверное многие из вас знают, что Adobe Photoshop и Adobe Fireworks сжимают изображения не оптимально и после нарезки макета в Photoshop’e (Fireworks’e) изображения в большинстве случаев можно ужать. В среднем на дополнительном сжатии без потери качества небольшого сайта можно сэкономить килобайт 10, уж не говоря о разного рода фотогаллереях или сайтов с большим количеством графики. Немало, особенно на высоконагруженных проектах! Существует довольно много консольных программ для сжатия картинок без потери качества, а через консоль работать достаточно неудобно, и это отнимает время разработчика. Около месяца назад наткнулся на программу под названием ImageOptim.

Она прогоняет картинки через консольные оптимизаторы изображении (AdvPNG from AdvanceCOMP, OptiPNG, PngCrush, JpegOptim, Jpegtran from libjpeg и опционально PNGOUT) и выбирает лучший алгоритм для сжатия, и самое главное она имеет очень удобный визуальный интерфейс. Достаточно просто перетащить изображение или папку с изображениями в окно ImageOptim и все. К сожалению программа рассчитана на работу только с png и jpg форматами и не поддерживает gif.

Спешу расстроить пользователей Windows, есть только версия программы под Mac. Те кто использует Windows, могут обратить внимание на сервис smush.it — это онлайновый оптимизатор графики, также есть расширение для Firefox. Одним из преимуществ сервиса над ImageOptim является возможность оптимизации анимированных gif.

Добавьте кармы перенесу в блог разработчиков. Если кому понравилась статья, можете подписаться на мой блог, так как не все публикую на хабре, да и записи в блоге появляются раньше чем здесь на пару дней.

upd. Перенес в Web-разработку

upd2. В комментах подсказали, что есть программа с аналогичным функционалом под windows, называется PictureBeaver. Сам сию утилиту не тестировал, так что кто пользуется отпишитесь плз. Автор кстати москвич Артём Сапегин.
