Screenshot text is sharp in the source but becomes illegible after several resize operations.

Problem

Screenshot text is sharp in the source but becomes illegible after several resize operations.

Solution

Root Cause / Diagnostic:
Successive scaling passes (e.g., rasterizing, shrinking, adjusting, and re-scaling) trigger cumulative interpolation degradation and bilinear blur. Downsampling raster screenshot typography below its native grid without smart object vectorization destroys character legibility.

Actionable Fix:
1. Convert screenshot assets into Smart Objects in Photoshop (or keep vector text layers native) before performing any transformation or downscaling.
2. Re-type critical headline numbers or labels using heavy sans-serif vector fonts (e.g., Montserrat Black or Impact) sized at 60+ pt directly on top of the screenshot.
3. Downsample final exports in a single bicubic sharper step, verifying crisp letterforms at 100% and 25% preview scaling.

Pro Tip:
Never scale down raw raster UI text; manually re-type the crucial 3 words using native vector typography sized for instant mobile legibility.
