imgproxy Hosting Live In 5 Minutes

imgproxy hosting on xCloud gives you a self-hosted image processing server that resizes, converts and optimizes images on demand through a signed HTTP API. Deploy imgproxy from the OneClick catalog and xCloud starts the pinned 4.0.15 community image as one stateless container, generates the URL-signing key and salt, applies your allowed source prefixes, bounds image sizes and publishes the API over HTTPS. Originals stay in your own storage.

What is imgproxy?

imgproxy is, in its README's words, a fast and secure standalone server for resizing, processing and converting images, guided by simplicity, speed and security. You give it a source image URL and processing options in a specially crafted URL, and it fetches the image, processes it and serves the result, which offloads image work from your application. The open-source edition handles formats such as JPEG, PNG, GIF, WebP, AVIF and JPEG XL, with resizing, cropping, rotating, watermarking and filters. Self-hosted imgproxy is a server you run yourself instead of a hosted image service. It is licensed under Apache-2.0.

As deployed on xCloud, the template runs imgproxy 4.0.15, pinned by digest, as one stateless container with no volume. Requests must carry a signature made from the generated key and salt, and sources are limited by the prefixes you enter at install. imgproxy Pro is not included, and nothing is stored on the server.

From Sign-Up to a Live imgproxy Endpoint In Just 3 Easy Steps

Self-hosting a signed image-processing API normally means a container, a signing setup, source restrictions, a domain and a certificate before a single image is resized. This is the same result without assembling any of it.

  1. Step 01

    Sign Up

    Create your xCloud account and pick imgproxy from the OneClick catalog. Enter a site title, domain and your trusted allowed source URL prefixes.

  2. Step 02

    We Deploy It For You

    One click. We bring up the vendor-maintained imgproxy 4.0.15 image pinned by immutable digest, generate a 32-byte HMAC signing key and salt, and publish the API over HTTPS on your domain.

  3. Step 03

    Sign Your First Request

    Store the generated key and salt in the client that builds imgproxy URLs. Generate an HMAC-SHA256 signature for a processing path, request the signed HTTPS URL, and confirm the resized image comes back.

Everything imgproxy Does, On Your Own Server

imgproxy runs in full here — signed, on-demand image resizing and optimization, on infrastructure you control.

  • Signed Processing API

    Every resize, convert or optimize request must carry a valid HMAC-SHA256 signature, or imgproxy rejects it outright.

  • SSRF-Hardened Sources

    Loopback, link-local and private source addresses are denied by default, on top of your own allowed source URL prefixes.

  • Bounded Resource Use

    Source resolution, file size, output dimensions, workers and queue depth are all capped in the template, so each request stays within set limits.

  • Fast Resize And Optimize

    Convert and resize remote images on demand and serve the optimized result straight from the API.

  • Fully Stateless

    No source images or results are stored server-side — your own storage and CDN remain the source of truth.

  • Restart-Safe Signing

    The signing key and salt stay stable across an xCloud Restart, so already-signed URLs keep working.

What You Can Do With imgproxy

  • Serve responsive images on demand

    Your site asks for each image at the exact size and format a page needs, and imgproxy produces it from the original.

  • Keep originals in your own storage

    Images stay in your own bucket or server, and imgproxy fetches them only from the source prefixes you allow.

  • Offload image code from your app

    Your application only builds a signed URL, rather than shipping its own resizing and conversion code.

  • Optimize without a hosted image service

    A team that does not want its images transformed by a third-party service runs the transformation on a server it controls.

imgproxy vs Alternatives

Cloudinary
imgproxy processes images fetched from the source prefixes you allow and stores nothing, on a server you run. This page makes no feature-parity claim with Cloudinary.
imgix
imgproxy takes processing options in a signed URL and returns the result from your own server, with source restrictions set at install. This page makes no feature-parity claim with imgix.
Imagor
Imagor has its own OneClick page. imgproxy signs each processing path with an HMAC-SHA256 key and salt; compare the two URL formats and signing schemes before choosing.
Thumbor
Thumbor has its own OneClick page. imgproxy uses its own processing URL format, so existing Thumbor-style URLs need rewriting before a move.

Hear what people are saying about us

See why agencies, developers, startups, and growing businesses choose xCloud to power their projects.

xCloud works really well, I am surprised by its performance being this the release version, I have tried many paid platforms such as runcloud, cloudpages or serveravatar, as well as free platforms such as CyberPanel, CloudPanel or Hestia Control Panel and direct competitors such as SpinupWP and FlyWP. Of all those that I have tried, the platform that works best for WordPress is SpinupWP and I believe that xCloud can reach and surpass that development, its roadmap is promising. Congratulations to the xCloud team, I hope they become the leading platform in the segment, it has all the potential to achieve it!

I've been with runcloud for the last 3 years. However, after trying xcloud for the last month, I'm switching over. They are on a roll with their setup.

I'm moving my servers to xCloud, a cloud control panel by M Asif Rahman and the WPDeveloper team. Their roadmap looks interesting and no, there are no team mates nor API limits with xCloud! #xCloud #wordpress #hosting

xCloud is like having an expert server team on call — without the big agency costs. It's given me back my time and given my clients peace of mind. Highly recommended for freelancers and small teams who want reliable performance and security.
Dumitru Butucel
xCloud isn't just a solution. It's like one of that friend who got your back when you screw things up pretty bad.
Waqar Ahmed
Trust me when I say, once people explore the potential of xCloud they gonna switch from other panels, just keep delivering the best tech, lots of love for the team 😍😍
Rahul Singh
So far my experience has been smooth like silk. I didn't imagine that configuring and managing a VPS would be so easy. As of today, I have deployed 8 sites. The support is good, and they treat users with respect, even if they ask stupid questions (myself included). For the future, I hope for greater flexibility in scheduled backups and more comprehensive and consistent documentation. I'm sure that within a few months, xCloud will become the leader in its segment. This community is amazing, and the Staff here is super helpful.
Massimo Villa
Came from cloudways then to runcloud then to xcloud. Looks like I'm staying here.
Gerson El
I've recently taken all of my Vultr-hosted sites and gotten rid of cPanel for them to substitute it with xCloud. I have to say, I'm really impressed with xCloud so far! The interface is definitely the standout feature for me.
Tony Lewis
I came from Cloudways and won't go back. Highly impressed with xCloud. Glad I gave them a chance.
Jared McDowell
I like xCloud better than RunCloud, but one thing I'll point out is that some years ago RunCloud was hungry for business, the support was outstanding, and the community was active and helped each other. Maybe it was sold, there was a change in management, or they stopped being hungry, but the quality of the RunCloud offering declined and it hasn't been moving forward quickly. My point is that currently the xCloud team has the edge and it is theirs to keep or lose

How Kevin Heinrichs Cut Hosting Costs by 84% While Running WooCommerce & Node.js Sites Efficiently

I had 150 sites on cloudways and am in the process of moving them to xcloud. Much faster and better priced.
Dan Spinoza
Dear xCloud Team, I have been using xCloud for some time now and am genuinely impressed with its capabilities and the flexibility it offers by allowing users to bring their own VPS for management. It's a fantastic service, and my experience so far has been very positive. Successful migrated 5 sites on a single server. Xcloud migration tool worked great. There were few hiccups with security plugin like MalCare but disabling the plugin prior to migration worked just fine.

Frequently Asked Questions

Feel free to contact us with any questions or concerns you may have.

Is imgproxy free?

Yes. The imgproxy community edition is open source under Apache-2.0, and the pinned v4.0.15 tag's licence file is linked here. xCloud bills for the Cloud VPS under it, not for imgproxy. imgproxy Pro and other commercial products are separate and not included here.

Can you self-host imgproxy with Docker?

Yes, and this imgproxy Docker hosting template does it for you: the community darthsim/imgproxy image, pinned by digest, runs as one stateless container on your own server, with HTTPS in front of port 8080. It is not an imgproxy cloud account, so images pass through your server.

How much RAM does imgproxy need?

Minimum requirements for imgproxy are 1024 MB of RAM, 1 CPU core and 2 GB of disk. High-resolution or concurrent workloads need more memory and CPU, and the template bounds workers to two. The 6 GB tier offered here is ample.

How do I sign an imgproxy request?

Build the processing path, prepend the decoded salt, compute an HMAC-SHA256 digest with the decoded key, and URL-safe base64 encode it, then request the signed path from your API URL. The imgproxy signing guide has examples. Unsigned or wrongly signed requests are rejected.

What sources can imgproxy fetch from?

The install form asks for allowed source URL prefixes. The default https:// permits signed requests to fetch any public HTTPS image, so for production enter exact trusted prefixes with a trailing slash. Loopback, link-local and private-network sources are rejected.

Can I rotate the imgproxy signing key and salt?

Yes. Update IMGPROXY_KEY and IMGPROXY_SALT together in the Environment editor, restart the app, and update every signing client at the same time. Old signed URLs stop working afterwards. Store the key and salt with your API-client recovery configuration.

Is there a limit on imgproxy image size or output?

Yes. The template bounds source images to 50 megapixels and 50 MiB, result dimensions to 4096 pixels, animated processing to one frame, workers to two and the waiting queue to 20 requests. Raise them only after measuring memory, CPU and abuse exposure.

What should I back up for imgproxy?

Nothing on the server: imgproxy is stateless and declares no data volume, so there is no volume to back up. Source images and results are request-scoped and not stored. Keep durable originals in your own storage, and keep the signing key and salt in your recovery notes.

How do I upgrade imgproxy?

A running install stays on its pinned version until you adopt a newer template version, so catalog updates leave it alone. Review the release notes and configuration compatibility first, then test a few signed URLs after the move. There is no stored data to migrate.

Is imgproxy an alternative to Cloudinary?

imgproxy covers on-demand image resizing and conversion: it fetches images from your allowed sources, processes them and returns the result, on your own server. This page makes no feature-parity or speed claim with Cloudinary, so test your transformations.

Can I cancel anytime?

Yes. There is no lock-in — cancel any time. Hosting is billed monthly and charged for what you actually use, so when you delete the server the unused balance is refunded to your account, less up to 10% in payment-processing fees.
