Choosing an image upscale factor from 1× to 8×
Choose 2×, 4× or 8× image enlargement based on your source, target dimensions and viewing size. Learn how each scale uses credits.

Start with the dimensions you need
Choose an output size for the place the image will be used, rather than automatically selecting the largest factor. A social post, marketplace product photo and large print have different requirements. Doubling width and height produces four times as many pixels; multiplying both by eight produces 64 times as many pixels. Larger dimensions also mean larger files and more work when opening or editing the output.
2× for a moderate enlargement
For a 500 × 500 pixel source within our processing-size limit, 2× produces 1000 × 1000 pixels. Plus uses its native 2× model for this factor; Lite resizes its compact 4× restoration to the requested 2× size. It is a practical first choice when an image needs a moderate increase in size. A 1× request uses the selected enhancement model and returns a result at the prepared source dimensions.
4× for the native larger restoration
The same 500 × 500 source at 4× produces 2000 × 2000 pixels. This factor uses the native 4× model directly. A 3× request resizes the 4× restoration down to 1500 × 1500. Compare a representative crop before committing to a large batch, particularly for faces, small text or delicate textures.
5×–8× when larger dimensions are useful
Factors above 4× enlarge the 4× AI restoration with Lanczos resizing. At 8×, the example image becomes 4000 × 4000 pixels. This can be useful for a target canvas or layout, but the extra enlargement does not add another native AI detail-recovery stage. An 8× result is not automatically sharper than 4× when both are displayed at the same physical size.
Credits, access and the prepared source
Lite costs one credit per image at 1×–4× and two at 5×–8×. Plus costs two credits per image at 1×–4× and four at 5×–8×. Lite is the default when no model is chosen. Paid upscaler access enables larger factors and batch processing; the account and pricing pages show your current access. Images above 2500 pixels on their longest side are reduced to that processing base before enlargement, preserving the aspect ratio. The selected factor applies to that prepared size, not to the larger original upload.
