Image Upscaler output sizes
Choose 2x or 4x for the size you need
Select the scale that fits the final use of the image. Larger output dimensions require more processing credits.
4x for a larger output
Choose 4x when the source is small and the final placement genuinely needs additional pixels.
Credits based on output size
The workbench shows the exact credit cost and estimated dimensions before processing.
Built for this job
Use an AI Image Upscaler to increase image resolution without simply stretching pixels
The image upscaler increases output dimensions while using surrounding photo information to reduce the blocky appearance of basic resizing.
2x or 4x output
Increase both dimensions while keeping the image proportions intact.
Preserved proportions
Keep the original aspect ratio while increasing image width and height.
Photo-focused processing
Use the current modes for photos rather than fidelity-critical text, logos, or graphics.
How it works
How to upscale an image online
1
Upload the source photo
Choose the cleanest JPG, PNG, or WebP file available. Avoid a screenshot of an already compressed copy when possible.
2
Choose 2x or 4x
Select a scale based on the final display size instead of increasing dimensions without a purpose.
3
Process the image
See the exact credit cost, then process the photo at the selected scale.
Upscaling adds pixels, not lost facts
AI can make a low-resolution image more usable at a larger size, but it cannot guarantee perfectly accurate detail that was never present in the source.
- Use 2x when you need a modest size increase; choose 4x only when the larger output is genuinely useful.
- Very tiny, heavily compressed, or severely blurred images can still show artifacts after upscaling.
- For slight softness or compression blur, use Unblur Image instead of relying on resolution alone.
