How do I increase the resolution of an image?

Upload it, choose 2×, 4× or a target size, and download the result. 2× doubles width and height, and 4× quadruples them, so 4× gives 16 times the pixels. You can also pick up to 10 photos and run them as a batch, each charged separately.

How do I convert a low resolution photo to high resolution?

Use 4× on a small photo, then check it with the Compare slider. A 960 px photo reaches 3840 px, which is 4K, and a 1920 px photo reaches 8K. The AI restores detail, but it can't rebuild what is completely missing.

How do I increase resolution of an image to 300 DPI?

Open the Print size helper, type your print width and height and keep DPI at 300. It shows the pixels needed, says whether 2× or 4× gets there, and writes 300 DPI into the file.

How can I fix a low resolution photo for free?

New accounts get 30 free credits once, with no card and no watermark. That covers a few 2× upscales. Later use comes from paid plans on the pricing page.

Can I improve resolution without AI?

Yes. Standard mode is a classic resize that invents no detail, and it costs 2 credits. The default AI resolution enhancer restores detail while it enlarges.

Can I improve photo resolution on my phone?

Yes. Open the site in your phone browser, sign in, upload a photo and pick 2× or 4×. There is no app. HEIC photos work only where the browser can open them, such as Safari.

Originals and results sit in private storage and download through short-lived links. There is no public gallery, so you can improve image resolution on family photos without sharing them.

Fixes when you improve resolution of image files

“Free upscalers stop after a few tries, stamp a watermark or want a subscription”
Sign up with email for 30 free credits, once, with no card and no watermark; more use needs a paid plan.
“You can't add detail that isn't there”
The AI restores edges and texture while it enlarges, and the Compare slider shows the change, though detail that is fully gone can't come back. Use it to enhance resolution of picture files that look soft.
“Faces come out waxy and over-smoothed”
Start with 2× to improve picture resolution gently, compare it with the original, then re-run at 4× for more size; smoothing can still happen.
“My photo is too small to print at 300 DPI”
The Print size helper takes your width, height and DPI, shows the pixels needed and writes that DPI into the file, though a very blurry source stays soft.

“It's the only photo I have of my grandmother”
Scan the print and upload it. You can increase resolution of picture scans 2× or 4× in private storage, though there is no face repair or scratch removal.

Improve resolution of image to the size you need

Choose an Output size to increase image resolution to an exact long edge. Image Upscale picks 2× or 4× for you and resizes the result to match. This table shows how small a source can be and still get there.

Output size	Long edge	Source needed at 4×	Source needed at 2×
HD 720p	1280 px	320 px	640 px
Full HD 1080p	1920 px	480 px	960 px
2K	2560 px	640 px	1280 px
4K	3840 px	960 px	1920 px
8K	7680 px	1920 px	3840 px
16K	15,360 px	3840 px	Not reachable

Picture resolution here means pixels on the long edge, with the aspect ratio kept. Uploads are capped at 3840 px on the long edge. For a print, type the size and DPI into the Print size helper, which shows the pixels you need.
