Increase image resolution online

First decide whether you need more pixels or information that is no longer readable. Re-export from the source file when you have it. For a bitmap, choose a method based on whether changes to its details are acceptable.

You have a vector or layered source

For text, logos, charts and layouts, export the target size from the design source. This preserves the original letterforms and layout without asking AI to guess unreadable characters.

You only need different pixel dimensions

If the content is clear but a website or layout needs a larger image, use basic resizing in an image editor. Interpolation adds pixels; it cannot recover details that were never captured.

Some regenerated detail is acceptable

For photos and illustrations, try AI enhancement and compare the result with the source. aiimage4k offers 2K and 4K requests. Processing may alter textures, text or lines, so the result should not be treated as factual reconstruction.

Important details are already unreadable

Look for the camera original, a less compressed copy or take another photo. Product labels and document text need accurate source information. Do not rely on details guessed by AI.

Frequently asked questions

Will a blurry photo become sharp?
