Increase image resolution without losing quality
Low-resolution photo, a tiny download or a cropped screenshot? Add real pixels with AI — not just a bigger, blurrier copy. 2K, 4K, 8K or an exact print size.
- Real pixels, not stretched

Quick answer
How do you increase image resolution online?
To increase image resolution online, upload the picture to Kenerate AI's upscaler, choose a size and download the result: AI adds real pixels and rebuilds detail as it enlarges, up to 8K or 128 MP. Changing DPI adds no pixels, so it does not increase resolution. There is no watermark, and it is free to start.

How it works
How to increase the resolution of an image online
Three steps, no app to install.

- Steps
- 3 steps
Step 1
Upload the low-resolution image
Add a JPG, PNG or WEBP up to 25 MB to the Kenerate upscaler.
Step 2
Choose how much resolution
Real-ESRGAN adds resolution in one pass. For a set size choose Image Upscaler → 2K, 4K or 8K, or Kenerate Upscale → 4 to 128 megapixels.
Step 3
Download the high-resolution version
Compare at 100% and download — the pixel size is shown with the result. No watermark.
See it in the app
Open Image Upscaler and upload a photo, or pick one from your library or a link.

Common mistake
Does changing DPI increase resolution?
No. Resolution is the number of pixels — for example 1200 × 800. DPI (or PPI) is only a note in the file telling a printer how many of those pixels to fit into an inch.
- Change a 1200 × 800 image from 72 to 300 DPI without resampling and it still has 1200 × 800 pixels — it just prints smaller (4 × 2.7 in instead of 16.7 × 11.1 in).
- To get a sharper, bigger image you need more pixels. A normal resize adds them by averaging neighbours, which looks soft.
- AI upscaling adds pixels and rebuilds edges and texture, so the higher-resolution version actually looks sharper.

More pixels vs better pixels
Both sides have the same pixel count: the left was resized normally, the right was upscaled with AI.
Reference
What resolution do I need to print a photo?
For a sharp print aim for 300 pixels per inch. Multiply the print size in inches by 300:
| Pixels at 300 PPI | |
|---|---|
| 4×6 in | 1200 × 1800 px |
| 5×7 in | 1500 × 2100 px |
| 8×10 in | 2400 × 3000 px |
| A4 | 2480 × 3508 px |
| A3 | 3508 × 4961 px |
Kenerate Upscale lets you pick an exact megapixel size and shows the pixel dimensions for your photo before you run it.

FAQ
Image resolution questions
8 questions
How do I increase image resolution online?
Upload it to an AI upscaler such as Kenerate, pick a size (for example 4K) and download the result. AI adds real pixels and rebuilds edges, so the higher-resolution image is sharper than one enlarged in a normal image editor. New accounts get free credits on sign-up.
Link to this answerDoes changing DPI increase resolution?
No. DPI (or PPI) is only a print setting stored in the file. Changing 72 to 300 DPI without resampling keeps exactly the same pixels — the print just gets smaller. To really increase resolution you need more pixels, which is what upscaling adds.
Link to this answerHow do I increase resolution without losing quality?
Use an AI upscaler instead of a plain resize. Normal enlarging (bicubic) spreads existing pixels and looks soft; AI super-resolution adds plausible detail as it enlarges.
Link to this answerDoes resizing an image increase its resolution?
Resizing with resampling adds pixels, so the pixel resolution goes up, but a normal resize only interpolates and the image looks soft. Resizing without resampling, or only changing the DPI, keeps exactly the same pixels. An AI upscaler resizes and rebuilds edges and texture at the same time, so the higher resolution also looks sharper.
Link to this answerCan I increase the resolution of a low-quality photo for free?
Kenerate gives free credits on sign-up to test it, with no watermark.
Link to this answerWhat resolution do I need to print a photo?
About 300 pixels per inch: 1200 × 1800 px for a 4×6 in print, 2400 × 3000 px for 8×10 in, 2480 × 3508 px for A4. Kenerate Upscale lets you pick an exact megapixel size.

PPI, DPI and how many pixels you need
The difference between pixels and print density, and real size targets from labs and platforms — with sources.
On this page
PPI vs DPI
Adobe draws the line clearly: PPI is the pixel density of the digital image; DPI is the dots of ink a printer lays down — and 300 PPI is a go-to setting for high-quality print [1]. Changing the number in the file doesn't add pixels; only resampling or upscaling does.
What labs and platforms ask for
AI resolution vs Super Resolution
Adobe's Super Resolution (2021) doubles the width and height of a photo — four times the pixels — and writes a new DNG [6]. Online AI upscalers go further (to 8K or 128 MP here) and work on any format, but both are making educated guesses about detail that wasn't captured.
