A text graphic needs a different quality check from a photograph. Viewers must be able to read the words quickly, often on a small phone screen. A beautiful desktop layout can fail when its footnotes, thin type, or long paragraphs are reduced. Compression settings cannot rescue lettering that is too small in the design itself.
This page starts with PNG at the source dimensions, with no crop and sharpening off. Supply a finished raster export from your design app. The tool does not add headlines, replace fonts, draw icons, or rebuild a low-resolution screenshot as editable text. If the writing is already blurry, export again from the original design rather than trying to sharpen the screenshot.
Before using the tool, shorten the copy and give it a clear hierarchy. A main point, a supporting line, and a small amount of context are easier to read than a dense paragraph. Make sure important words have sufficient contrast against the background. Keep essential information away from the edges so you have room to adjust a later crop or accommodate a platform preview without cutting into the text.
