Screenshot Upscaler - Make Low-Resolution Screenshots Crisp

The best fix for a small screenshot is a bigger capture. If you can, take it again on a high-density display, with the window maximized or the browser zoomed in. Upscaling adds pixels, but a native capture starts with real ones.

When you cannot retake it, such as an old bug report or someone else’s image, upscale the file you have. Use the original PNG rather than a copy that was already compressed in a chat app, because compression noise around text gets enlarged along with everything else.

PNG keeps sharp edges exactly, while JPG blurs them with compression. A screenshot saved as JPG already has halos around letters, and enlarging it makes those halos bigger. If a JPG is all you have, expect to see some of that noise in the result.

Upload as PNG when you can and export as PNG too. Reserve JPG or WebP for the final delivery copy when file size matters, and make that copy last so it is the only lossy step.

An AI model rebuilds edges, and for large clear text it does a good job. For very small text it may redraw a letter or a digit slightly differently from the original. That is fine for a slide or a tutorial but risky for an invoice, a contract, or a table of numbers.

Compare any text that carries meaning against the original capture, character by character. If the content must be exact, publish the original or retype the text instead of relying on a reconstruction.

Slides and documents usually look right at 2x. Use 4x when the screenshot will be shown very large, such as a hero image or a printed poster. Bigger is not always better, because pushing the scale further gives the model more room to invent detail.

Check the result at the final size, then at 100 percent zoom for text and icon edges. When a straight line looks wavy or a rounded corner looks lumpy, go back to a smaller scale. Keep the original capture next to the enlarged copy.
