This release brings again bugfixes, recording improvements and localization updates. The biggest announcement is maybe that I stop supporting Snap, please see my announcement for details.

This release provides updated translations. Thanks for all the translators who provided up-to-date translations of the many changes 1.2.0 brought.

Peek's translations are overall in a pretty good shape, but there are still incomplete translation. So if Peek is not yet available in your native language, the translation is incomplete or you spot any errors, head over to Weblate and help translating :)

This release of Peek brings many changes, among them an improved user interface, improved stability and hugely reduced resource usage. The highlights:

  • A new user interface with quick format selection, display of elapsed time during recording and better error reporting
  • The RAM and disk space usage during GIF generation was reduced significantly due to Peek no longer relying on ImageMagick for GIF generation but using Ffmpeg directly
  • Optional support for the awesome gifski GIF generator, which allows high quality GIF animations
  • Support recording APNG files

Special thanks go to Alessandro (@gort818) who implemented the new UI with format selection and time display. That's very much appreciated, good work there. And thanks to all the translators and everybody who contributed by reporting issues and giving feedback.


See the installation instructions for details on how to get and install Peek. I maintain the Ubuntu PPA, Flatpak repository, Snap packages and Arch AUR packages myself, so they are already up-to-date. Other package repositories might take a while until they get updated, but you can always install from source, too.

Using gifski

Peek now supports gifski, a new GIF encoder written by Kornel Lesiński, who known for his work on ImageOptim. gifski provides awesome quality for GIF animations. By cleverly combining separate frames it can create GIFs that display thousands of colors in a single frame. If the gifski executable is found in the path Peek will show a setting to enable gifski for GIF encoding. You can also select the quality level. Encoding with gfiski will be slower than the default and especially on the higher quality settings files will be significantly larger, but depending on what you record the quality can be amazing. Just give it a try!

As gifski is a pretty new software only your distribution likely does not offer a package for it. But you can download pre-compiled binaries from gifski's release page or install from source. Once you have placed the gifski executable in your path open Peek's preferences and enable "Use gifski for high quality GIFs".

Deprecation of avconv backend

The avconv backend Peek currently still supports is deprecated and I will likely be removing it in one of the next releases. Since major distributions have switched back to Ffmpeg and avconv is lacking behind in regards to format support needed for Peek it has become unpractical to support it. You can't use it for APNG and GIF generation, so if you use it Peek will fall back to using ImageMagick (with all the issues this had) for GIF and won't support APNG at all. The avconv backend is also mostly untested. Please get in touch if you actually still have to rely on avconv to use Peek.

Next steps

I will likely release a new minor version soon with updated translations and bug fixes if something pops up. Help in translating and reporting issues is very much appreciated for this. Apart from this I have marked a few features that I would like to get tackled for the next release. No promise everything will make it, but those are the things I am currently interested in getting done next. If you want to help on this or you have a specific thing you want to get done, feel free to get in touch and submit pull requests.

Another update with mainly bug fixes, translation updates but also some smaller tweaks. Unfortunately I did not tackle the big issue of ImageMagick having too strict resource limits on some systems (Ubuntu and Debian mainly), but I did not want to delay this release further.

The changes in this release:

  • feat: Finish saving file when closing window while rendering (#142)
  • feat: Highlight file when launching Dolphin file manager
  • recording: Use raw video for recording GIF with GNOME Shell recorder (this
    is identical to how FFmpeg recorder works) (#116)
  • fix: Failed to record MP4 when dimensions where not divisible by 2 (#141)
  • fix: Make sure recording starts after countdown is hidden (#146)
  • fix: Closing window while recording could leave temp files behind

  • i18n: Updated translations for Basque, Esperanto, French, Portuguese (Brazil),
    Russian and Ukrainian
  • docs: Added man page (#136)
  • package: Removed dark theme hack for Flatpak (proper theme support is part of
    Flatpak now)
  • package: Updated dependencies for Flatpak and Snap packages

    FFmpeg encoder

This is the 1.0 release of Peek, the simple screen recorder for animated GIFs and now also WebM and MP4.

The highlights of this release are:

  • Wayland! Peek now works in a GNOME Shell Wayland session
  • WebM and MP4 are supported as output formats in addition to animated GIFs
  • Keyboard shortcut to start / stop recording
  • Use built-in GNOME Shell recording functionality instead of FFmpeg when running in GNOME Shell
  • Various resource usage optimizations, which should avoid most of the issues people ran into while recording
  • Peek can now easily be installed with Flatpak on all distributions supporting it.

Thanks again to all contributors who provided pull requests, reported bugs and feature requests and translated Peek in 19 languages.


See the installation instructions for details on how to get and install Peek. I maintain the Ubuntu PPA, Arch AUR packages and Flatpak repository myself, so they are already up-to-date. Other package repositories might take a while until they get updated, but you can always install from source, too.

What comes next?

Peek has now all the features I originally imagined for a complete release, hence the 1.0 version number. But this does not mean it is finished, there are many great ideas how to improve Peek. As I stated earlier and want to keep Peek focused on its main task of creating short screencasts of screen areas.

My immediate plan going forward is as follows:

  1. Make a small follow up release with updated translations and, if necessary, bug fixes soon. I need your help here, so if you use Peek please report all issues you find. And if you speak a language other than English, consider to help translate Peek.
  2. Improve the UI of Peek to give better feedback on progress and errors and allow easy access to recorded files (see #21, #49, and #58)

After that I would like to evaluate more advanced feature requests and see if and how they could be implemented. But development will likely slow down a bit at that point, as I have to focus more on other projects.
