What this image upscaler is for
Use it when you have one photo or AI still to enlarge. Check the credit cost first, then download the larger file.
Check source fit before spending
Start at 2K and inspect faces, text, edges, and repeated patterns. Upscaling can enlarge visible structure, but it cannot recreate detail that is absent from the source.
2K, 4K, 8K, and format control
Pick target size plus Auto, JPEG, PNG, or WebP before the job starts, without sending unsupported provider parameters.
Text, scans, and screenshots
Choose "Text or scanned document" for pages with small or soft text: the upscaler denoises, restores contrast, and sharpens strokes, then enlarges to 2K-8K. Source detail that is physically absent cannot be recreated.
See the cost before every run
The selected image resolution shows its credit cost before processing. Video is a separate model-based workflow with duration pricing.
Account history stays nearby
Use My Creations to reuse previous uploads and finished outputs without rebuilding the task from zero.

Real proof before you spend credits
Use a visible source/output comparison, source-fit checks, and credit context before choosing 2K or 4K.
Owned before/after proof
The comparison uses a self-authored SVG source and its SeedVR2 2K output, so it does not rely on customer or stock media.
Source-fit check first
Clean images, product shots, AI art, and usable portraits fit this lane. Old damaged faces should start in photo enhancement, and motion clips belong in video upscaling.
Credit cost stays visible
The tool shows the selected resolution cost before generation and keeps task context when a low-balance checkout is needed.
Fallback from failed ComfyUI setup
When missing nodes, model downloads, VAE issues, or 8GB VRAM tuning block local work, the browser flow lets the asset ship first.
What should and should not use this page
| Source | Fit | Best path | Watch for |
|---|---|---|---|
| Clean photo or thumbnail | Good fit | /tools/upscaler | Run 2K before 4K if faces or text matter |
| AI art or generated still | Good fit | /tools/upscaler | Check hands, texture, borders, and repeated patterns |
| Product image or listing asset | Good fit | /tools/crystal-upscaler | Reject changed logos, labels, and straight edges |
| Old or damaged portrait | Use with caution | /tools/photo-enhance first | Identity can change even when sharpness improves |
| Transparent PNG or cutout | Use with edge review | /tools/crystal-upscaler | Preview on light and dark backgrounds for halos |
How to upscale one image with SeedVR2
Use this sequence for photos, AI art, thumbnails, and product images.
- Step 1
Add the best source you have
Upload the cleanest image source you have, or use a supported direct image URL. Avoid normal webpages and chat share links.
- Step 2
Set condition, resolution, and format
Choose the source condition, 2K, 4K, or 8K output, and Auto, JPEG, PNG, or WebP. Use the separate video tool for clips.
- Step 3
Submit once the cost is clear
The selected resolution shows the credit cost before you start. If credits are short, the pricing popup keeps the task context for checkout.
- Step 4
Review and download the result
After the result is unlocked, compare the original and full-resolution output in the same panel before downloading the final file.
Production notes
SeedVR2 can enlarge structure and reduce visible compression, but it cannot guarantee recovery of detail that is absent from the source. Test 2K before spending more credits on 4K.
The available controls are source condition, target resolution, and output format. Source condition records what you want reviewed; it is not a promise that every defect will be removed.
Image cost depends on output resolution. Video cost depends on verified duration, resolution, and the selected model.
The processed result stays hidden until you unlock it; an eligible account claims this same processed 2K as its free first task. Later credit jobs use the balance shown before submission.
SeedVR2 upscaler FAQ
The questions visitors ask before spending credits on an online upscale.
Is the SeedVR2 upscaler free?
A new signed-in account can finish one 2K image free. After that every job costs credits, the exact amount is shown before you run, and credit packs are one-time and do not expire.
Does it work on a Mac?
Yes. The upscaler runs in the browser, so Apple Silicon and Intel Macs work without a CUDA GPU or a local ComfyUI install — you only need a supported browser and a connection.
Should I run the 3B or the 7B model?
Locally, the 3B checkpoint or a GGUF quant is the safer start on 8 GB cards, while 7B wants more VRAM and runs slower but can hold more texture. The browser upscaler runs without managing that choice.
Can I upscale several files at once?
Images run one file per job so you can check quality before spending more credits. Run sources with similar characteristics together and use the per-job credit cost to estimate a larger session.
Can I use it without signing up?
You can open the tool and preview the workflow, but guests only see a locked preview. Signing in unlocks the first free 2K image and lets a failed job's credits return automatically.
Choose the workflow that matches your source
Still images, old photos, video clips, and pricing checks need different next steps. Pick the right lane before spending credits.
