👋 Hey Developers, Welcome!
If you’ve ever struggled with hosting images or run out of server storage, this post is for you.
Today, I’m going to show you how to upload images to Cloudinary using PHP — with my
ready-made PHP script that you can use completely free.
Think of me sitting right beside you, walking you through each step. You don’t need advanced
coding knowledge — I’ve already written all the PHP code.
All you have to do is connect it with your Cloudinary account, add your credentials, and you’ll
be uploading images online in minutes.
Let’s dive right in! 🚀

☁️ Why Use Cloudinary for Image Hosting?
Before we start, let me quickly explain *why* Cloudinary is the best option for image hosting
especially if you’re a PHP developer.
Cloudinary is a powerful cloud-based media platform that hosts, optimizes, and delivers your images
through a global CDN. That means your images load fast anywhere in the world
no more slow hosting or limited storage.
Here’s what makes Cloudinary awesome:
* 🌍 Free plan with generous storage and bandwidth.
* ⚡ Super-fast delivery via global CDN.
* 🧩 Easy PHP integration using simple API keys.
* 🔒 Secure & reliable file management.
* 🖼️ Automatic optimization for speed and quality.
So if you’re building a PHP project and need image uploads
Cloudinary is the smartest, easiest, and most professional choice.
Step 1: Create Your Free Cloudinary Account
Alright, let’s set up your Cloudinary account.
Open a new tab and go to [Cloudinary.com](https://cloudinary.com/).
Click “Sign Up for Free”, and fill in your basic details (or use your Google account).
Once you log in, you’ll land on your Cloudinary Dashboard.
Here you’ll find your three most important credentials:
* Cloud Name
* API Key
* API Secret
These are like the keys to your Cloudinary account.
Your PHP script needs them to upload files securely.
👉 Important: Never share your API Secret publicly — treat it like a password.
You’ll only use it once inside your private `config.php` file.
If you forget where to find your credentials, go to Dashboard → Settings → API Keys.
Step 2: Add Your Cloudinary Credentials to `config.php`
Now let’s connect your Cloudinary account to your PHP script.
Go to your project folder and open the file named `config.php`.
Inside, you’ll see some placeholder text for Cloud Name, API Key, and API Secret.
Here’s what you do:
1. Copy your credentials from your Cloudinary Dashboard.2. Paste them in the correct spots in the `config.php` file.3. Save the file.
That’s it — you’ve successfully connected your PHP script with Cloudinary. 🎉
From now on, every image you upload through your script will go straight
to your Cloudinary Media Library.
If you’re sharing this script publicly, leave those fields blank and tell your users
to fill in their own keys.
That way, everyone can use their personal Cloudinary account.
Step 3: How the Upload Process Works
Let me explain what’s happening behind the scenes when you upload an image.
When you choose a file and click the upload button:
1. Your PHP script grabs the file.
2. It connects to Cloudinary using the credentials from `config.php`.
3. Cloudinary receives the image, stores it on their secure servers, and returns a public URL.
4. You can display or save that URL anywhere — on your website, blog, or app.
And just like that, your images are hosted online and delivered lightning-fast
via Cloudinary’s CDN.
No need to worry about server storage, bandwidth, or optimization — Cloudinary does
it all for you automatically.
Step 4: Test Everything Step-by-Step
Let’s test your setup together — this part is exciting.
✅ Make sure your internet connection is active.
✅ Confirm that you’ve added your API details in `config.php`.
✅ Open your PHP script in the browser.
You should now see the upload form. Choose any image (like `photo.jpg` or `banner.png`)
and hit Upload.
Wait a few seconds... and boom 💥 — your image will upload to Cloudinary instantly!
You’ll see a success message along with the image’s secure Cloudinary URL.
If you check your Cloudinary Dashboard → Media Library, you’ll see your image sitting right there.
Congratulations — your PHP script is fully connected and working perfectly! 🎯
Include a simple README.txt file explaining how to add Cloudinary keys.
Keep your folder names clean and organized (like `upload.php`, `config.php`, `index.php`).
Add clear instructions or comments inside your files.
Make sure users can upload immediately after entering their keys — no editing needed.
Add user feedback like “Upload successful!” or “Please select a file.”
That’s what makes your script “plug and play.” Anyone can download it,
enter their API info, and start uploading in minutes.
Step 5: My Personal Tips for You
After building and testing this script many times, here are a few golden tips from my experience:
1. Test multiple image formats
Try JPG, PNG, and GIF files to make sure all upload smoothly.
2. Keep your credentials private
Never upload your real `config.php` to GitHub or share it with others.
3. Monitor your usage
Cloudinary’s free plan is generous, but always keep an eye on your dashboard stats.
4. Add a preview feature
A small image preview before upload gives users confidence that it’s working.
5. Use descriptive file names
It’s easier to manage images later if filenames make sense.
These small details make your script more polished and professional.
