Demo files are processed temporarily and should not contain sensitive information.

  • Try the real workflow

    Use your own file and inspect a downloadable result before building anything.

  • Real media processing

    Uppy sends the upload into a live Transloadit Assembly, not a browser-only mock.

  • Ready for your product

    Move the same capability into uploads, cloud imports, storage, and delivery.

Make every image fit the product

Turn a one-off edit into a repeatable visual system

The useful version of an image is rarely just one file. Create the crops, sizes, formats, and visual treatments each surface needs, then connect the outputs directly to storage and delivery.

  • Consistent presentation

    Apply the same crop, dimensions, and visual treatment to every incoming image.

  • One source, many variants

    Create thumbnails, social crops, and high-resolution output in parallel.

  • Faster experiences

    Optimize delivery weight while retaining the quality your interface needs.

  • Composable edits

    Combine enhancement, background handling, watermarking, and format conversion.

  • Content-aware logic

    Use detected metadata to filter or branch before expensive processing runs.

  • Smart CDN variants

    Deliver exact dimensions from the edge instead of storing every possible copy.

Three steps, no installation

Go beyond a one-off file tool

Change the URL. Deliver the exact asset each screen needs.

The interesting part

The original stays untouched. Each URL can request the exact variant a screen needs, while repeat requests are served from the CDN cache.

Frequently asked questions

How does the Blur image tool work?

Upload a supported image file, run the tool, and download the blurred image. The page sends your upload through Uppy into a real Transloadit Assembly, so the result demonstrates the same processing platform available through the API.

What is the maximum file size?

Files can be up to 25 MB on this public utility. Production workflows can accept larger files, process batches, import directly from cloud storage, and create several outputs in parallel.

Are uploaded files stored permanently?

The public tool processes files temporarily. Do not upload sensitive material. A production workspace gives you control over authentication, storage destinations, and retention.

Can I automate blur image with an API?

Yes. The same processing capability is available through reusable Transloadit Templates. Trigger it from Uppy, a backend SDK, an API request, or a Smart CDN URL, then send results to storage and services you control.

What other file tools are available?

Browse the image tools category for related utilities. Each page runs a real upload and produces a downloadable result.

Process uploads, batches, and cloud files with one workflow

Move this same capability into your product: process customer uploads and cloud files, then route the results to storage, webhooks, and delivery.
