Increase Image Resolution · Turn Low Res Photos into High Resolution Images

Upload it, choose Upscale 2x or 4x if the photo is clean but small, or Restore at 2K or 4K if it is also blurry or noisy, then click Increase Resolution and download. A 1000 px photo becomes 2000 or 4000 px wide in one pass.

Yes, with AI. A plain resize invents new pixels by averaging their neighbors, which looks soft. AI upscaling predicts detail that fits the picture, so edges, text and texture stay crisp at the larger size. Quality still depends on the source: a sharp small photo upscales far better than a blurry one.

A high res image has enough pixels for its use: about 1920 px wide for full-screen web, 3840 × 2160 for a 4K screen, and 300 pixels per inch for print. A low resolution photo has too few, often because it is a screenshot, a thumbnail, a chat-app copy or a heavy crop. A super low resolution image under about 200 px can be enlarged, but tiny faces in it cannot be recovered exactly.

To make it smaller, any resize option works: Image Size in Photoshop, Adjust Size in Mac Preview or Resize in Windows Photos. Changing the resolution of an image upward is different, because it needs new detail rather than stretched pixels, so use an AI upscaler such as Upscale 2x or 4x here.

Here is how to improve a low resolution photo: find the largest copy you have, use Upscale if it is clean but small, or Restore if it is also blurry, blocky or grainy, and check the result at the size you will use it. That is also how to fix a low resolution photo that a print lab rejects; compare its pixels with the guide above.

Run Restore at 4K first to rebuild detail, then Upscale the result if you need more pixels. Judge the result at the size you will actually print or post, since faces that were only a few pixels wide have to be estimated.

Upscale does not: it is a faithful enlarger that adds pixels without changing faces, text or content. Restore uses a generative model to rebuild detail in blurry or damaged photos, so it can redraw fine texture such as skin pores, hair or fabric weave slightly differently. Compare the slider and use Upscale when every detail must match the original.

No. Resolution is the pixel count, for example 2400 × 3000. DPI only tells a printer how densely to place those pixels, so changing DPI alone adds no detail. For a sharp 8x10 at 300 DPI you need 2400 × 3000 pixels: increase the pixels here, then set the DPI value.

You can try it free: new accounts get free credits when they sign up, so you can increase the resolution of a few photos and compare the results. After that, each job uses credits from your balance. If you need the opposite, any resize tool works as a resolution lowerer, and the low quality image maker is a low res image generator for memes.

Only upload photos you have the right to edit, such as your own pictures, family photos or images you have permission to use. Increasing the resolution of someone else’s photo or artwork does not give you the right to reuse or sell it.
