Vovsoft Batch Image Upscaler: AI Enlargement for Whole Folders, Offline
Batch Image Upscaler is a $19 Windows program from Vovsoft that enlarges JPG, PNG and WEBP pictures up to 4x with an AI model running on your own graphics card. The $19 is a one-time lifetime license, and nothing is uploaded anywhere.
If you have a folder of old scans or small product photos, ordinary resizing just gives you bigger blur, and online upscalers tend to charge per image or make you send your pictures to a server.

Overview
Batch Image Upscaler has two tabs. On Images you add files or a whole folder and see each one listed with its size, then Next takes you to Options and the run itself. It works as a queue that you fill and start, not as an image editor.
Under the hood it uses Real-ESRGAN, the open super-resolution model family named in Vovsoft's version history, and it ships with the binaries and trained models included, so you don't set up Python or CUDA yourself. Vovsoft released version 1.0 in February 2025 and has added a Status column, Unicode filename support and high-DPI fixes since.
The Images tab with eight JPG files queued, the Add Files and Add Folder buttons, and Next to move on to the options.
Features
Up to 4x enlargement that adds detail
Batch Image Upscaler predicts the pixels a low-resolution picture is missing rather than stretching the ones it has, which is the difference between upscaling and plain resizing. It enlarges up to four times the original size.
Separate modes for artwork and photos
Batch Image Upscaler has an Artwork mode for illustrations, anime and vector-style images, where sharp clean edges matter, and a Photo mode for real-life pictures, where natural texture matters. You pick one for the run.
Folders at a time
Batch Image Upscaler takes individual files or an entire folder and processes the list in one go, with a Status column showing where each file stands, so a few hundred scans don't need a few hundred clicks.
Runs on your own GPU, offline
Batch Image Upscaler uses the Vulkan driver, so Intel, AMD and Nvidia cards all work, and no data is sent to the internet. That matters for client photos, family pictures and anything else you'd rather not upload.
Benefits
- A flat cost. $19 once, instead of credits or a monthly plan priced by image count.
- Private by default. Everything stays on the PC.
- Portable option. The portable edition runs from a folder without an install, with the models included.
Real-World Uses
- Old family photos. Enlarge low-resolution scans before printing them.
- Shop catalogues. Bring small supplier images up to the size a store page needs.
- Anime and game art. Scale up wallpapers or sprites with Artwork mode.
- Print preparation. Enlarge a batch of web-sized images before they go to a print layout.
Who It's For, and Who Should Skip It
Batch Image Upscaler suits Windows users who enlarge many images at once and want a simple queue, a one-time price and no uploads.
Skip it if you upscale only an occasional picture, since a free online tool or a free desktop upscaler will do. Skip it too if you need to fine-tune each image, because it is a batch tool with no retouching. A PC without a Vulkan-capable graphics card, or a 32-bit Windows, can't run it.
Usage Guide
- Install Batch Image Upscaler or unzip the portable edition.
- On the Images tab, click Add Files or Add Folder.
- Click Next to open the Options tab.
- Set the options there, including Artwork or Photo to match the pictures.
- Start the run and watch the Status column.
- Check a few results at full size before you delete any originals.
Before you buy
- Test on your own GPU. The speed depends on your graphics card, so run a small batch in the trial first.
- The trial is for personal use only and shows a nag screen and ads.
- No refund if you change your mind. Vovsoft's policy is no refunds in general because a trial is available, with exceptions at its discretion, and PayPro Global has the final say on orders placed there.
- One license, one person. It can go on several of your own PCs. A business with multiple users needs more licenses.
Where it falls short
- Little control over output size. One buyer upscaling mixed resolutions said his results ranged from 2 MB to 50 MB and wanted finer control.
- A clear-list complaint. The same buyer reported that the clear function didn't work and that he had to close the program before loading a new folder.
- AI guesses. Super-resolution invents plausible detail. Faces and small text can come out looking different from the original, so don't use it where exact detail is evidence.

Customer reviews on the vendor's page
Richard Watts: "Great software which does what it claims!"
Eugene Holdcroft: "The product does what it claims, but I wish there was more fine control of the upscaling. The photos that I’m upscaling aren’t all the same resolution, so I end up with 2Mb files and 50Mb files. I don’t want 50Mb files. Also, the clear function doesn’t appear to work. I have to close the program before I upload a new folder or the program grabs too many photos."
JP: "speed, friendliness, reliability"
Independent coverage
Trisha, TrishTech.com, February 2025: "Vovsoft Batch Image Upscaler is a powerful yet easy-to-use tool that brings AI-driven image enhancement to your desktop."
Praise centers on the program doing what it says at a low price, and the criticism is about control: output sizes and the file list. Independent testing of its quality against other upscalers is scarce.
Comparisons
Batch Image Upscaler vs online AI upscalers
Online services need no install or graphics card and often give better previews, but they usually limit free use and take your images onto their servers. Batch Image Upscaler costs $19 once and keeps files local, at the price of needing a suitable GPU.
Batch Image Upscaler vs Upscayl
Upscayl is a free desktop AI upscaler that also handles batches on your own machine. If your budget is zero, try it first. Batch Image Upscaler's appeal is a very plain queue-style window and a paid developer behind it.
Batch Image Upscaler vs Vovsoft Batch Image Resizer
Vovsoft's Batch Image Resizer changes dimensions quickly without adding detail, which suits shrinking or exact sizes. Use the upscaler when a picture must get larger and still look sharp.

Does Batch Image Upscaler work without an internet connection?
Batch Image Upscaler runs entirely on your PC with its models included, and no data is sent to the internet.
Will Batch Image Upscaler run without a dedicated graphics card?
Batch Image Upscaler needs a graphics processor with Vulkan support. Most modern PCs have one, including many with integrated Intel or AMD graphics, but speed varies a lot, so test it in the trial.
Can Batch Image Upscaler enlarge more than 4x?
Batch Image Upscaler goes up to 4x in a run. Anything larger would need a second pass or a different tool.
Can I use Batch Image Upscaler results commercially?
Batch Image Upscaler's license allows commercial use, while the trial does not.

Batch Image Upscaler is a one-time $19 purchase. The license doesn't expire and includes future updates.

- A graphics card with Vulkan support
- 41.84 MB for the installer or 43.01 MB for the portable edition
Conclusion
Batch Image Upscaler is worth $19 if you regularly enlarge batches of pictures on a Windows PC with a capable GPU and want them kept private. The one reason to buy it is a local AI upscaling queue at a flat one-time price. The main reason not to is that free tools do the same basic job, and this one gives you little control over the result. Try a small mixed batch in the trial first.
