Frequently Asked Questions

Why do my screenshots look blurry in presentations?
Screenshots are often captured at a low pixel count and then stretched to fill a slide, which softens text. Upscaling 2x or 4x first gives you enough pixels to display sharply at presentation size.
Can the upscaler sharpen tiny UI text?
It reconstructs edges as it enlarges, which makes small interface text noticeably more readable. For the cleanest result, start from the highest-resolution capture you can take.
Is upscaling screenshots free?
Yes — it is free, unlimited and watermark-free. The full-resolution image downloads instantly.
