gThumb Image Viewer como alternativa Linux ao Windows Photo Viewer
Atualizado em
Nossa avaliação
gThumb is a capable replacement for Windows Photo Viewer if you're comfortable with a slightly heavier app that does more. It opens all common image formats quickly and supports fullscreen viewing, zoom, keyboard navigation, and slideshow—core needs are met. However, it’s part of the GNOME ecosystem and feels more feature-rich than minimal, which may slow startup on older systems. If you want basic viewing with clean controls and don’t need editing or organizing tools, simpler alternatives like Eye of GNOME or Mirage might suit better. For users who occasionally edit or manage small photo sets, gThumb works well.

Abrindo seus arquivos do Windows Photo Viewer
gThumb opens all image formats used by Windows Photo Viewer—JPEG, PNG, BMP, and GIF—without issue. It also supports additional formats like TIFF, RAW, and TGA, which can be helpful. You can view and save changes to these files directly. There's no need for conversion when moving from Windows Photo Viewer, and metadata such as EXIF is preserved. Exporting or saving in different formats is supported through the 'Save As' and batch tools, making format flexibility a plus.

Can gThumb open HEIC or WebP images?
Yes, if the required GStreamer plugins or codecs are installed. WebP is usually supported by default on modern systems. HEIC may require installing additional packages like libheif.
Is gThumb slow to start compared to Windows Photo Viewer?
It can be slightly slower, especially on older hardware, because it loads more features at startup. For pure speed, lightweight viewers like Eye of GNOME or Mirage may feel snappier.
Can I disable the editing and catalog features to make it simpler?
You can't fully remove them, but you can ignore the side panel and avoid catalogs. Use it in fullscreen or simple view mode to keep the experience focused on viewing.
