Real results
Real upscale results for Instagram: drag to compare
These are generated sample images, not customer photos. Each saved 270 × 360 px input was processed at 4× with the same Real-ESRGAN model and tiling used by this tool, producing 1080 × 1440 px. The output was saved as WebP without retouching. Drag to compare; the original is stretched to the same display size.

Portraits
A small portrait for a feed post: compare the curls and knitwear, then check the face for invented details.
BeforeAfter 4×
Pets and fur
A pet photo for a post: compare the fur and grass; fine texture is estimated, not recovered.
BeforeAfter 4×
Illustrations
An illustration for a carousel: compare outlines and small details before using it as a slide background.

Night shots and signs
A street scene for a post: compare the neon sign, but do not rely on the model to restore tiny lettering.
Example: prepare the portrait for a post
The portrait above grows from 270 × 360 to 1080 × 1440 px. That is 1080 px wide, but taller than the 1080 × 1350 post preset: fitting that frame requires cropping or adding space. Inspect the face before publishing.
Example: use the illustration in a grid
The illustration above also reaches 1080 × 1440 px at 4×. That is enough pixels for one 1080 px-wide tile, not three across: those need about 3240 px of source width. Starting with a larger image may be necessary.
Three steps
How to upscale image files online
1.Add your picture
Open Upscale Image and press Upload image, drop a file on the page or paste one. JPG, PNG, WebP and iPhone HEIC all open.
2.Pick 2×, 4× or a size
2× is free without an account; 4× and target sizes need sign-in and an AI credit for each image. Check the estimated output size before you start.
3.Compare and download
Drag across the close-up to check the detail, then press Download, or send the picture on to a grid or a split.
How big
Upscale image size by 2×, 4× or to exact pixels
Choose a multiplier or a target size and the tool works out the scale. Output can fall short of the target when the image reaches the size limit. Target sizes require sign-in and one AI credit per image.
- 2×Upscale image width and height by two. Free every day, no account.
- 4×Upscale image width and height by four, for small web pictures.
- To a sizeInstagram post, Story, 4K or a width you type.

For Instagram
Upscale image files for Instagram posts and Stories
A photo saved from a chat may have fewer pixels than you need for a post or Story. Upscale it, inspect the face and lettering, then download it or send it to the Instagram grid maker. Upscaling adds pixels, but cannot guarantee how Instagram will display or compress the result.
Planning a wall of posts? Three 1080 px-wide tiles need a picture about 3240 px across. Check the output dimensions and size limit, then split it into an Instagram grid. For slides, try the carousel maker. More dimensions are in the Instagram grid size guide.

Private by design
Upscale image files privately: nothing is uploaded
Upscale Image sends the model to your browser instead of sending your picture to our servers. Client work, family photos and unreleased product shots are processed on your own device.
- The model comes to youReal-ESRGAN (realesr-general-x4v3), about 5 MB, is downloaded to your browser.
- Your device does the workONNX Runtime Web uses WebGPU when available, with a WebAssembly fallback.
- Our server sees no pixelsSigned-in 4× and target-size runs use a server-side credit balance; the image stays on your device.
Limits
How large can you upscale an image?
This tool caps output at 16 megapixels and 8,000 px on the long side. Smaller pictures can get the full scale; larger ones may be capped or too large to upscale. Device and browser memory can also affect whether a run succeeds.
| Scale | Largest input | For example | Result |
|---|---|---|---|
| 2× | 4 MP | 2000 × 2000 px | 4000 × 4000 px |
| 4× | 1 MP | 1000 × 1000 px | 4000 × 4000 px |
Files up to 50 MB. The long side of a result stops at 8,000 px.

For print
Upscale a photo before you print it
300 pixels per inch is a common print planning reference, though requirements vary by printer and viewing distance. Upscaling increases the pixel dimensions, but does not guarantee print quality. Inspect the result closely and check your print provider's requirements.
| Picture | Prints at | After upscaling |
|---|---|---|
| Thumbnail or preview600 × 800 px | 5.1 × 6.8 | 20.3 × 27.14× · 2400 × 3200 px |
| Small web photo800 × 1000 px | 6.8 × 8.5 | 27.1 × 33.94× · 3200 × 4000 px |
| Messaging-app photo1200 × 1600 px | 10.2 × 13.5 | 29.3 × 39.02.88× · 3456 × 4608 px |
Going bigger than your printer's paper? Upscale first, then split the image across A4 pages and tape the sheets into a poster.
Know what to expect
What an image upscaler fixes, and what it can't
Upscale Image works well on
- Soft phone photos and old digital-camera pictures
- Small web images, thumbnails and screenshots
- Illustrations, logos and AI-generated pictures
- JPEG blocks and jagged edges
Will not rescue
- A face or subject that is out of focus
- Text that was never readable
- Motion blur from a moving camera
- Colour, exposure or old-photo scratches
Upscale Image adds resolution; it is not a retoucher. The model estimates detail it cannot see, so always look over faces, hands and small lettering in the close-up before you post or print.
