Edit Text in an Image
Open a flattened PNG and click a headline: there is no text cursor, because the letters are pixels alongside the background. Without the source document, correcting that headline involves removing the old letter shapes and reconstructing the image beneath them.
An exported workshop poster illustrates the problem. Its title may sit over a gradient with a decorative line behind the letters. Covering the title with a solid rectangle removes part of the design as well as the text; a careful correction must account for that hidden background.
A diagram presents a different challenge. Replacing a short label beside an arrow should not change the arrowhead, line thickness or a nearby measurement. Identify those boundaries before editing, and keep the original to check whether anything outside the intended wording changed.
Preserving the original font, font weight, color and perspective keeps a correction consistent with the artwork. A serif caption should retain its serifs and light strokes; a cream title should match the existing cream; lettering on an angled panel should follow that panel's direction. A plausible replacement still needs a spelling check.
Clean exports with large, legible text are easier to assess than tiny compressed graphics. If thick letters hide a textured background, the missing detail may be ambiguous. Return to the source file when exact artwork, numerical precision or brand compliance is essential.
An exported graphic can contain arbitrary fonts, gradients and illustration. In contrast, text in a screenshot often follows interface grids and system font rendering. Baseline alignment and native display scale matter especially for that case.
Frequently asked questions
Does a PNG retain editable text from my design app?
A normal PNG export stores pixels rather than original text layers. Keep the source design document if you expect to revise wording regularly.
Why is a rectangle a poor way to cover a headline?
It covers the background as well as the letters. Gradients, textures and lines then disappear, leaving a visible patch even when the replacement wording is correct.
What should I inspect beside an edited diagram label?
Check arrowheads, connector lines, units and neighboring labels. Small changes to those details can alter the meaning of a diagram.
