Choose JPG quality (missing feature)

[dawidd4]

In XnConvert or irfanView you can change resolutions of multiple images.

• You can select how many pixels the longer side of a photo should have,
• when resizing you want to sharpen slightly the images (MS Paint sharpens the images when making them smaller without asking), (I use "Unsharp Mask" with values: Radius: 0.3, Amount: 40.0, Threshold: 0, when scaling images down, with the Lanczos algorithm. MS-Paint uses more aggressive filters but the results are decent)
• you can choose the JPG quality (75%, 80%, 85%, 90%, any number - I usually choose 80%)

In Right Gallery, I can only choose the percentage size of multiple selected photos. How do I know how big the % should be to get, let's say, 2560px on the longer side? And why can't I choose the JPG quality in the settings? In "Google Snapseed" I can choose between JPG 80%, JPG 95% and JPG 100% when saving edited images.

It's primarily a Gallery app, for viewing photos. For editing, there are only basic functions here. There are specialized applications for quality editing.
