Jinova Compute · Image Upscale

Upscale images without the guesswork.

Enlarge images at 2x or 4x, faithfully or with AI reconstruction. See the price before you run, and nothing is charged unless you approve it.

Up to 50 images at a time, and each one succeeds or fails on its own.

  • Two methods
  • 2x and 4x
  • Up to 50 per batch
  • Price before you run

Drag the handle to compare the original with Jinova's result. Full image shows light web previews. Detail loads the exact benchmark files and shows the centre of the image at the output's own pixel size, which is where upscaling is actually judged.

Enhance can reconstruct a heavily compressed or low-resolution source into a more usable image. It may infer plausible detail rather than recover information that no longer exists.

Real Jinova benchmark output. No manual retouching. Original: Antonio Rotta, portrait of Lattanzio Querena, 1850. Public domain.

Two methods

Two different jobs, not two settings.

Preserve keeps the original faithful. Enhance rebuilds detail a poor source no longer has. They run separately, with separate limits, and you choose before you are priced.

Preserve

Keep it faithful.

Keeps what is in your image and does not invent detail.

Choose Preserve when the original is already usable and you do not want Jinova inventing missing detail. It enlarges what is there, predictably, with no generative step. Best for product images, screenshots, logos, text and photographs that are already good.

  • Source sizeUp to 12.5 megapixels
  • Sizes2x and 4x
  • You receivePNG, JPEG or WebP

The default. It does not restore detail that is missing from the source.

Enhance

Rebuild poor detail.

May infer plausible detail that is not in your original.

Choose Enhance when the source is low-resolution, heavily compressed or soft and you accept AI reconstruction. It can turn a damaged image into a more usable one, but the detail it adds is inferred, not recovered.

  • Source sizeUp to 1.8 megapixels
  • Sizes2x and 4x
  • You receivePNG

Accepts smaller sources than Preserve, and returns PNG only.

Preserve is selected unless you change it, so you cannot end up with reconstructed detail you did not ask for.

A starting point, not a rule. If an image has to stay exactly true to its source, Preserve is the safer choice.

Pricing

See the price before you run.

Jinova prices the job first, shows you the most it can cost for the images you added, and waits for your approval before anything runs.

  1. 01

    You approve the amount

    Nothing is charged unless you approve it and the job goes ahead.

  2. 02

    Priced in the console

    Current prices and payment terms are shown in the Jinova console before you approve anything.

  3. 03

    Your approval sets the limit

    You are never charged more than the amount you approve.

  4. 04

    Change something, re-price

    Adding an image or changing a size clears the total rather than leaving a stale number on screen looking payable.

The terms for Jinova Compute purchases are published in the Jinova console.

Batches

One bad image does not ruin the batch.

Add up to 50 images. They are priced together and processed individually, so a single problem file never takes the rest down with it.

Per image, not per batch

Each image succeeds or fails on its own. There is no state in which the whole batch is simply marked failed.

Failures explain themselves

A failed image says what happened in plain language and what to do about it, rather than showing you an error code.

Retry just that one

Try a failed image again without re-running the images that already worked.

Close the tab safely

A batch is recoverable from its id. Refresh, close the tab, or come back tomorrow and your images are still there.

If something goes wrongExample

  • Source changed

    The source file changed after pricing. Upload it again to continue.

  • Took too long

    This image took too long and was stopped. You can try it again.

The other images in the batch carry on regardless, and you can retry a failed one on its own.

One method per batch

A batch runs Preserve or Enhance, chosen before it is priced. A single total cannot honestly describe a mixed batch, so the choice is made once.

File type per image

The output file type is set per image, with an apply-to-all control when you want one. A set of fifty is rarely one kind of image.

Formats and limits

What goes in, what comes out.

Two sizes and the formats people actually have. Everything here is enforced by the service, so nothing is a surprise at upload time. The source limit depends on which method you choose.

Sizes

  • 2xDouble the width and height
  • 4xFour times the width and height

Accepted input

  • JPEG
  • PNG
  • WebP

You receive

  • PNGLossless. Both methods
  • JPEGPreserve only
  • WebPPreserve only, up to 16,383 px a side

Per image

  • 12.5 MPSource, Preserve
  • 1.8 MPSource, Enhance
  • 5,000 pxLongest edge
  • 30 MBUpload size

Enhance returns PNG only. HEIC and HEIF files are not accepted, so convert those to JPEG or PNG before uploading.

How it works

  1. 01

    Upload

    Add one image or up to fifty.

  2. 02

Before you upload

The practical questions.

Your images stay yours

You keep ownership of everything you upload and everything Jinova produces for you. We process your files to deliver your result and for nothing else.

An account is required

Uploading and processing happen inside a signed-in account, so your images and results are not sitting behind a public link.

Help if something goes wrong

If a job or a charge does not look right, contact us and we will look into it.

How we handle your data

What we collect, how long we keep it and who processes it is set out in our Privacy Policy.

Full detail is in our Privacy Policy and in the Jinova Compute terms shown in the console.

FAQ

Questions about upscaling with Jinova.

What it accepts, what it costs and what happens when something goes wrong.

What is the difference between Preserve and Enhance?

They are two different products, not two settings. Preserve is a faithful enlargement: it keeps what is in your image and avoids deliberately inventing detail, which makes it predictable. Enhance is AI reconstruction for poor-quality sources, and it may infer plausible detail that is not in your original. They run on separate systems, accept very different maximum sizes, and return different file types. Preserve is selected unless you change it, so you cannot end up with reconstructed detail you did not ask for.

Which one should I choose?

Preserve for logos, UI, product images and photographs that are already good, or whenever the result has to stay true to the source. Enhance for compressed, very small, soft or degraded images, where a faithful enlargement of a poor image would still be poor and you accept AI reconstruction. Treat that as a starting point rather than a rule.

Does Preserve improve image quality?

Preserve makes an image larger without deliberately inventing detail. It does not restore information that is missing from the source, so a blurred or heavily compressed original will still look that way, only larger. Enhance is the method designed to rebuild detail in those cases.

What types of images can I upscale?

JPEG, PNG and WebP files, with a longest edge of 5,000 pixels and an upload size of up to 30 MB. Preserve accepts sources up to 12.5 megapixels. Enhance accepts up to 1.8 megapixels, because it is doing far more work per pixel. HEIC and HEIF files are not accepted, so convert those to JPEG or PNG first.

How much larger can I make an image?

You can choose 2x or 4x, which double or quadruple the width and height. There is no 8x option. Running a 4x model twice to reach 8x would mean resampling an already generated result and selling the interpolation as an upscale, so it is deliberately not offered.

Can I process several images at once?

Yes. You can add up to 50 images to a batch. They are priced together, and then processed individually so that the outcome of one image does not depend on the others. A batch runs one method, chosen before it is priced, because a single total could not honestly describe a mixed batch. The output file type is set per image, with an apply-to-all control when you want one.

Can I use Enhance on a batch?

Yes. Enhance is available on batches in the same way Preserve is. The batch runs whichever method you chose, and Enhance's smaller source limit of 1.8 megapixels applies to every image in it.

Will I know the cost before processing?

Yes. Before anything runs, the console shows the most the images you have added can cost. Nothing is charged unless you approve that amount and the job goes ahead, and you are never charged more than the amount you approve. If you add an image or change a size afterwards, the amount is cleared and priced again rather than left on screen. Current prices, payment terms and the terms for Jinova Compute purchases are shown in the console.

What happens if part of a batch fails?

Only that image is affected. Each image succeeds or fails on its own, the failure is explained in plain language, and you can retry that image without re-running the ones that already worked. If a job or a charge does not look right, contact us and we will look into it.

What output do I receive?

From Preserve, a PNG, JPEG or WebP, whichever you choose: PNG is lossless and keeps transparency, JPEG is smaller for photographs but lossy and drops transparency, and WebP is smaller still and keeps transparency. Enhance returns PNG only.

What happens if I close the tab?

Your batch is recoverable. It is identified by a batch id rather than by anything held in the browser, so you can refresh, close the tab or come back later and still reach your images and results.

What happens to uploaded files?

You keep ownership of your images and results. Jinova processes your files to produce the result you asked for. What we collect, why, and how long we keep it is set out in our Privacy Policy at /privacy-policy/.

Does Jinova Compute do anything besides upscaling?

Yes. Image Upscale is one of the productised workloads you can run on Jinova Compute. The console also offers Transcribe recording and Lip-sync video.

Is Jinova Compute part of Jinova AI?

Yes. Jinova AI is the company and the wider platform for secure AI agents and business workflows. Jinova Compute is where it runs productised compute workloads, Image Upscale among them, and you use it in the Jinova console at app.jinovaai.com.

Upload an image. See the price. Decide.

No processing starts until you approve the price.

Image Upscale is one of the productised workloads on Jinova Compute: complex compute underneath, simple choices on top. It runs in the Jinova console at app.jinovaai.com.
