Text Is Where Upscalers Get Caught Lying
A slightly hallucinated tree branch is invisible; a slightly hallucinated letterform is gibberish. Text is the hardest content for AI enhancement because readers verify every stroke, which is why generic creative upscalers routinely turn small print into convincing nonsense. Upsampler's Precise Upscale (SeedVR2 / GAN) takes the opposite approach for textual content: it treats each letterform as structure to be sharpened, not repainted, preserving font characteristics, stroke weight, and the contrast between text and background while multiplying resolution.
Where Legible Text Actually Matters
The use cases are less glamorous than art and more consequential: scanned contracts and archival documents where every clause must stay verifiable, historical materials being digitized for research, screenshots in software documentation and bug reports, whiteboard photos from meetings, old signage and poster reproductions, and infographics that get reshared until compression destroys them. In each case the test is the same: can a reader zoom in and trust what they see? Upscaled output holds up to that test at print sizes and on high-DPI displays.
Practical Tips for Text-Heavy Images
Start from the least-compressed source you can find: a PNG screenshot beats a re-saved JPEG, and a 300 DPI scan beats a phone photo of the same page. Run Precise Upscale first; only reach for Creative Upscale on decorative display text where style matters more than fidelity, and always proofread AI-touched text before publishing. For documents destined for OCR, upscaling first measurably improves recognition accuracy on small print. Related workflows: scanned film and photo archives. Test a difficult scan on the free no-signup upscaler and zoom to 100% on the smallest print.
