Can this restore screenshot text after WhatsApp compression?

Yes for many cases, though tiny fonts may remain partially degraded.

Should I sharpen before removing artifacts?

No. Clean artifacts first to avoid emphasizing compression noise.

Yes, especially where small labels and chart lines need clean edges.

Remove JPEG artifacts from screenshots to clean blocky text edges and restore smoother gradients in shared captures.

Screenshots are often converted to JPEG by messaging apps and social platforms, creating ringing and block patterns around text.

Use Artifact Removal as the primary model for compression cleanup before any sharpening pass.

For documentation workflows, keep PNG originals and only use JPEG when file size constraints require it.
