XML Pretty Print

Resizing an image the right way preserves sharpness, keeps proportions correct, and delivers a clean output at whatever size or file size you need. Whether you are resizing for Instagram, reducing to 100KB for a web form, or preparing images for print, this guide covers everything you need to know.

You have a low-resolution image — a blurry product photo, an old family picture, a small logo, or an anime illustration and you need it sharper, larger and print-ready. Traditional resizing just stretches pixels and makes things worse. AI image upscaling works differently and in 2026, the technology has reached a point where free online tools deliver results that were once only possible with expensive desktop software.

You are reviewing a contract and need to circle a clause. You are marking up a student assignment and want to sketch a correction in the margin. You have a blueprint or technical diagram that needs annotations drawn directly on the page. In every case, the question is the same: how do you draw on a PDF without printing it, without buying Adobe Acrobat, and without spending ten minutes figuring out a complicated tool?
