Your image, enlarged
One free SeedVR2 preview, up to 720 px on the long edge. No signup or card. A smaller input copy is made only when you choose this mode.
One free 720 px preview. Full-resolution processing uses purchased credits; no subscription.
Sample input is AI-generated; the result was processed by the named FAL model.
The actual comparison
One submitted input. Two independent model calls. Pick a model to inspect the real result.
The source is original synthetic artwork. Inputs were downsampled and lightly compressed before submission; every after is the named fal endpoint’s real output. No CSS blur or separately generated after is used.

What is actually free?
One new image is processed by SeedVR2. We create an input copy no larger than 360 px on the long edge and enlarge that copy 2×, giving an output up to 720 px. The original on your device is not overwritten.
You can download the preview without a watermark. This is a limited AI trial, not unlimited free high-resolution processing and not a credit-card subscription.
The limits, in plain view
The trial uses fixed SeedVR2 settings and PNG output. You still need to confirm your image rights and adulthood, and complete the human verification.
A browser/account can use one preview; a daily network limit also applies. Shared office or household networks may share that allowance. If processing fails, the trial allowance is restored; uncertain upstream charges still count against our service budget.
When you need more pixels
Switch to full resolution to review model controls, 2×/4×/4K dimensions and the exact credit quote. SeedVR2 and Crystal do not have the same per-pixel price.
Full-resolution processing requires an account and credits. Public checkout is waiting for payment approval; do not mistake an administrator sandbox checkout for a way to buy real credits.
| Route | Output | Cost |
|---|---|---|
| Free preview | Up to 720 px long edge | $0; one image |
| SeedVR2 full resolution | Selected dimensions | 1 credit per whole output MP |
| Crystal full resolution | Selected dimensions | 7 credits per whole output MP |
1 credit = US$0.01. Full output MP are rounded up, with a 1 MP minimum. Public checkout remains pending.
Keep the result, check the detail
The comparison uses the real preview copy and real model output. Download the file only after checking faces, lettering and repeated texture.
AI enlargement generates plausible extra detail. For a faithful pixel-art enlargement without AI, use the local nearest-neighbor tool instead.
Questions before you process
Is signup required for the free image?
No. A private guest session is created after you explicitly agree to the image-processing terms. It is not a Google account or a marketing signup.
Why is the free output limited?
The small preview lets you inspect the model while keeping processing cost bounded. Larger dimensions and alternative models are separate paid jobs.
Is the free download watermarked?
No. The preview limit is in pixel dimensions, not a watermark. It is still an AI-enhanced image and may contain invented detail.
Original sources
Model controls and competitor descriptions are checked against the original references. Our own recommendation is not an independent award.
