Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
This version makes working with many images far more direct: you can see at
any time what will happen when you convert.
• Presets at a glance. When saving, BlibBlob now shows all existing presets. A
click picks up the name, and if it is already taken the button reads
“Overwrite” – so you can no longer overwrite one by accident.
• The list follows your settings. Target format, quality and target resolution
are updated immediately as soon as you change something on the right. If
images are selected, the change applies only to those, otherwise to all of
them.
• dpi and alpha channel per image. Both values can now be set for individual
images instead of only for the whole run.
• Two buttons fewer. “Apply to selection” and “Resolution” are no longer
needed because everything is updated in real time. The number of selected
images is now shown in the footer.
• More in the “Show values” window. Alongside format, quality and target
resolution it now also lists the configured dpi and how the alpha channel is
handled.
• More accurate watermarks. Rotated watermarks now sit exactly where they
should: even at 90 degrees they reach the image edge, and text is no longer
cut off.
• New accent colour “Blanched Almond” under Appearance.
