Krea

Choose three small details that matter to the image’s purpose: a seam, a label character and a straight edge. Inspect those areas at the same displayed size in the original and enlarged versions. Added texture may look attractive while changing the object. A product listing needs fidelity, whereas an illustrative background may permit creative detail.

Keep the original file. Name the output with the selected model and settings, and compare it without resaving either file through another tool. This makes it easier to distinguish an enhancement problem from later compression.

Krea’s usage guide describes near-real-time reporting, individual-plan credits that do not roll over, and purchased packs with a 90-day lifetime. Record the balance before an attempt and allow the usage view to update before recording the balance after it. Do not divide a subscription allowance by a guessed cost per image.

The API page is internally inconsistent about sharing app compute. Its detailed FAQ describes dollar-based API charges from a separate balance. Treat an API budget as unresolved until the account’s billing terms confirm it; do not buy an app plan solely on an assumption that it includes production API calls.

Proposed evaluation, not performed: use a Free account and a self-owned, non-confidential photo small enough for the available free upscaler. If the intended model or size is paid, stop at that boundary.

1. Record the original pixel dimensions and select the three inspection details.
2. Choose an available upscaler and note its shown unit cost before submitting.
3. Open the output at 100% and compare the same crops. Look for rewritten lettering, false edges and invented texture.
4. Check actual dimensions and file size, then reconcile the account usage after it updates.

Accept only an output that preserves the details required by the intended use. Leave the outcome and consumed units blank until this check is performed.
