What is Upscayl?

Upscayl is an AI image upscaler available as both desktop software and a cloud service.

Its free Desktop application uses Real-ESRGAN-based models and Vulkan processing to estimate additional detail while increasing an image’s pixel dimensions. It is available for compatible Windows, macOS and Linux systems.

Desktop users can:

Process images locally

Choose from several AI models

Add compatible custom models

Upscale folders in batches

Control output format and location

Use the software without per-image cloud credits

Upscayl Cloud moves processing to remote infrastructure. It works through a browser and adds features such as more models and formats, face enhancement, batch processing, storage and support for high-resolution outputs.

What is Let’s Enhance?

Let’s Enhance is an online image upscaler and enhancement service.

Users upload an image, choose an enlargement size and processing mode, and download the cloud-generated result. It is designed for photographs, AI artwork, logos, scanned images, ecommerce visuals and print preparation.

Current features include:

Enlargement from 2× to 16×

Plan-dependent outputs up to 512 megapixels

Prime processing for natural texture

Gentle enlargement for sources requiring conservative treatment

Old Photo processing

Custom output dimensions

Background removal

AI image generation

Print-size and DPI preparation

Upscayl works well as a testing platform for photographers because several models can be compared locally without using one cloud credit for every experiment.

Upscayl Cloud adds face enhancement and remote processing, making it more suitable when the computer lacks compatible graphics hardware.

Let’s Enhance’s Prime mode is designed around natural texture and portrait, product and photographic content. Its interface requires less model knowledge from the user.

Let’s Enhance places greater emphasis on print-oriented guidance. Users can define target dimensions and prepare higher-resolution outputs for posters, canvas, merchandise and other printed products.

Upscayl Cloud highlights color accuracy and high-resolution processing, while Desktop gives users direct control over the final file.

However, neither platform can decide whether an image is genuinely print-ready using pixel count alone.

You must also check:

Final print width and height

Effective pixels per inch

Viewing distance

Color profile

Compression

Sharpening

Printer requirements

Bleed and crop

Detail accuracy at physical size

Print decision

Let’s Enhance offers the more guided print workflow.

Upscayl is the better choice when you already understand print specifications and want more control over the source, model and final output.

Both products support batch-oriented workflows, but the experience differs.

Upscayl Desktop is attractive for repeated local jobs because it does not use cloud credits for every processed image. Performance depends on the computer’s GPU, available memory, image size and selected model.

Upscayl Cloud and Let’s Enhance move the hardware burden to remote systems. This is more convenient on a lightweight laptop, tablet or shared workstation, but processing allowances depend on current account and plan rules.

A fair speed comparison requires the same:

Source file

Output dimensions

Image format

Quality settings

Network conditions

Test time

Account priority

Desktop hardware

Upscayl Desktop speed is mainly affected by local graphics hardware, memory, selected model and output size. The project uses Vulkan, and unsupported or older graphics environments may prevent it from running correctly.

Cloud processing reduces local hardware requirements, but upload time, queue demand and plan priority may affect the experience.

Practical conclusion

Use Upscayl Desktop when you have compatible hardware and want to avoid uploads.

Use Upscayl Cloud when you want Upscayl without depending on local GPU performance.

Use Let’s Enhance when its guided cloud workflow is more important than local processing.

No precise “fastest” claim should be published without a dated, controlled benchmark.

Upscayl Desktop provides the clearest privacy-oriented workflow because the upscaling operation can occur locally.

That does not mean the entire computer is automatically private or secure. Users must still consider:

Cloud-synchronized folders

Device backups

Malware

Shared accounts

Remote-access tools

Storage encryption

Folder permissions

Upscayl’s current Cloud privacy policy says uploaded images are not used to train its AI models and that it does not sell personal information. Users should read the complete current policy before uploading sensitive files.

Let’s Enhance requires image upload for its main workflow. Review its current privacy, retention and account-deletion terms before processing confidential or client-controlled material.

Winner

Upscayl Desktop for users who need local processing and more direct file control.

For either cloud service, avoid uploading highly sensitive images unless the provider’s current terms and your own permissions support that use.

Free, open-source desktop application

Local image-processing option

Separate Cloud workflow

Choice between local and remote hardware

Multiple AI models

Custom-model support on Desktop

Suitable for technical users and straightforward everyday workflows

Where Upscayl is strongest

Upscayl is strongest when you want one upscaling ecosystem that can adapt to different situations: local processing for control and Upscayl Cloud for convenience.

Both options are available

Use the original camera file, scan or artwork export. Avoid processing a screenshot when a better source exists.

Match the model to the image

Photographs, portraits, illustrations and compressed graphics do not respond equally to one model.

Begin with a moderate scale

Try 2× or 4× before requesting a very large enlargement. More pixels do not always mean more accurate detail.

Compare equivalent dimensions

A 16× result should not be judged against a 4× result without resizing them to the same final dimensions.

Inspect important areas at 100%

Check eyes, hair, fingers, labels, logos, fine lines and repeated textures.

Review the intended output

A result that appears slightly soft at 100% may look excellent in a web layout or physical print. A highly sharpened result may look unnatural at normal size.

Keep the original

Save every enhanced result as a new file. Never overwrite the only copy of an important image.

Avoid repeated JPEG compression

Keep a high-quality master and create smaller delivery versions from it.

Verify commercial-use rights

Rights depend on the source image, selected model, third-party content and intended use. Upscaling an image does not create ownership of the original.
