How to Increase WordPress Upload Size and Memory Limit
Increasing the WordPress upload size and memory limit can be important when you experience problems uploading files, installing themes or plugins, or working with large media files.
In some WordPress websites, the default upload limit or PHP memory allocation may be too low for the website’s requirements.
One way to increase these limits is through the hosting control panel, especially when using cPanel.
This guide explains how to increase the WordPress upload size and memory limit using the MultiPHP INI Editor, and how to change the PHP version when necessary.
Why Increase the WordPress Upload Limit?
WordPress hosting environments usually define a maximum file upload size.
If you attempt to upload a file larger than the configured limit, WordPress may reject the upload.
This can affect files such as:
-
Large images
-
Videos
-
WordPress themes
-
Plugins
-
Backup files
-
Import files
-
Media libraries
Increasing the upload limit can make it easier to manage larger website files.
Why Increase the WordPress Memory Limit?
WordPress requires memory to run PHP processes.
Themes, plugins, page builders, and other features may consume additional server memory.
When the available memory is too low, you may experience problems such as:
-
Failed plugin installations
-
Failed theme uploads
-
Website errors
-
Slow admin dashboard
-
Import failures
-
PHP memory limit errors
Increasing the PHP memory limit can help provide WordPress with more resources when the hosting environment allows it.
How to Increase WordPress Upload Size Using cPanel
One of the easiest ways to increase upload limits is through cPanel.
The exact interface may vary depending on your hosting company, but the general process is similar.
Step 1: Log In to cPanel
Open your hosting control panel.
A typical cPanel URL may look similar to:
https://yourdomain.com:2083
Replace yourdomain.com with your actual domain name.
Enter your cPanel username and password to log in.
Step 2: Open MultiPHP INI Editor
After logging in to cPanel, locate:
MultiPHP INI Editor
This tool allows you to modify PHP configuration values for your website.
Open the tool to access the available PHP settings.
Step 3: Select Your Domain
Inside the MultiPHP INI Editor, you may see options such as:
-
Home Directory
-
Your website domain
Select the domain you want to modify.
This ensures that the PHP settings are applied to the correct website.
Step 4: Increase PHP Upload and Memory Values
After selecting the domain, you can modify the available PHP configuration values.
Common settings related to WordPress uploads and memory include:
-
upload_max_filesize -
post_max_size -
memory_limit -
max_execution_time -
max_input_time
You can increase these values according to your website requirements and hosting resources.
After making the changes, click Apply or save the configuration.
Then return to WordPress and check whether the upload size and memory limits have increased.
Common PHP Values for WordPress
The exact values should depend on your website and hosting plan.
For example, administrators may configure values such as:
upload_max_filesize = 128M
post_max_size = 128M
memory_limit = 256M
These values are only examples.
Your hosting provider may impose server-level limits that cannot be exceeded through cPanel alone.
Can You Choose Different Upload Limit Values?
Yes.
The values shown in tutorials are not mandatory.
You can configure different limits based on your website requirements and the resources provided by your hosting plan.
For example, a small website may require a lower limit, while a website that regularly uploads large media files may need a higher one.
How to Change the PHP Version in cPanel
The original guide also explains that you can change the PHP version through cPanel.
This can be useful when your WordPress website, theme, or plugins require a different PHP version.
Step 1: Open MultiPHP Manager
From cPanel, locate:
MultiPHP Manager
Open the tool.
Step 2: Select Your Website
Select the domain whose PHP version you want to change.
Step 3: Choose the PHP Version
Use the available dropdown menu to select the required PHP version.
Then apply the changes.
Your website should begin using the selected PHP version.
What If Changing the PHP Version Causes Errors?
Changing the PHP version may cause compatibility issues if your WordPress theme or plugins do not support the selected version.
If errors appear after changing PHP:
-
Return to MultiPHP Manager.
-
Select the affected domain.
-
Choose the previous PHP version.
-
Apply the changes.
Before changing PHP versions, it is useful to confirm that your website components support the selected version.
What Is WordPress Upload Size?
The WordPress upload size is the maximum size of a file that can be uploaded through WordPress.
The actual upload limit is usually controlled by PHP and hosting server settings.
These settings determine the maximum size for files uploaded through areas such as:
-
Media Library
-
Theme installation
-
Plugin installation
-
Import tools
If your upload file exceeds the limit, WordPress may display an error.
Why Is Upload Size Important for Websites?
Upload limits can affect how easily website owners manage content.
Websites may need to upload:
-
High-resolution images
-
Product files
-
Large themes
-
Plugins
-
Videos
-
Documents
-
Backups
A suitable upload limit provides greater flexibility when managing website content.
WordPress Upload Size and User Experience
Upload limits themselves do not directly make a website faster for visitors.
However, they can make website administration easier when large files need to be uploaded.
For website performance, file optimization is still important.
For example, uploading unnecessarily large images can slow down page loading even if the server allows large uploads.
Website Performance and File Size
Large files can affect website performance.
Website owners should therefore balance upload flexibility with file optimization.
Even when you increase the upload limit, you should still optimize files before uploading them.
Useful techniques include:
-
Image compression
-
Modern image formats
-
Code optimization
-
Removing unused files
WordPress Upload Limits and SEO
Increasing the maximum upload size does not directly improve search rankings.
However, website performance can influence user experience and technical SEO.
For this reason, website owners should focus on both:
-
Suitable server configuration
-
Optimized website files
Large unoptimized files can slow down the website, while properly optimized media can help improve loading performance.
Improve Website Performance With File Compression
File compression can help reduce the amount of data browsers need to download.
Website files that may be optimized include:
-
HTML
-
CSS
-
JavaScript
Reducing unnecessary code can help improve website efficiency.
However, code optimization should be performed carefully to avoid breaking website functionality.
Optimize Website Images
Images are often one of the largest parts of a webpage.
Optimizing images can help improve loading speed.
Useful image formats may include:
-
WebP
-
SVG
The best format depends on the type of image and where it is used.
WebP
WebP can provide smaller file sizes for many website images while maintaining good visual quality.
SVG
SVG is useful for scalable graphics such as:
-
Logos
-
Icons
-
Illustrations
Because SVG graphics are vector-based, they can scale to different screen sizes without losing sharpness.
Remove Unnecessary Website Files
Unused files can make website management more difficult and consume storage.
Examples may include:
-
Old images
-
Temporary files
-
Unused themes
-
Unused plugins
-
Old backup files
Removing unnecessary files can help keep your website environment cleaner.
Always make sure you have a backup before deleting important files.
Choose Suitable Web Hosting
Hosting plays an important role in WordPress performance and server limits.
A good hosting plan should provide sufficient:
-
Storage
-
Memory
-
CPU resources
-
PHP configuration flexibility
-
Technical support
Some hosting plans place strict limits on upload size and memory.
If your project requires larger files or more PHP resources, you may need a more suitable hosting plan.
WordPress Memory and Hosting Resources
Increasing the WordPress memory limit only helps when the hosting environment has enough resources available.
If your hosting account has strict memory limitations, changing WordPress settings alone may not provide additional physical server resources.
For websites with high requirements, consider hosting options such as:
-
VPS hosting
-
Cloud hosting
-
Dedicated hosting
depending on the size and complexity of the project.
How to Improve WordPress Performance
In addition to increasing upload and memory limits, website owners can improve WordPress performance by focusing on several areas.
Use Optimized Images
Compress large images before uploading them.
Remove Unnecessary Plugins
Too many plugins can increase website complexity.
Keep only the plugins you actually use.
Choose Reliable Hosting
Server quality can influence website speed and stability.
Keep WordPress Updated
Regularly update:
-
WordPress core
-
Themes
-
Plugins
Updates may include security and performance improvements.
Use Caching
Caching can reduce the amount of processing required when loading website pages.
WordPress Upload Size vs. Website Speed
It is important to understand that the upload limit and website speed are not the same thing.
The upload limit determines how large an uploaded file can be.
Website speed depends on factors such as:
-
Hosting
-
Server response time
-
File sizes
-
Images
-
Plugins
-
Theme quality
-
Caching
-
Database performance
Increasing the upload limit simply gives administrators more flexibility.
It does not automatically make the website faster.
WordPress Memory Limit vs. Upload Limit
These two settings control different things.
Upload Limit
Controls the maximum file size you can upload.
Common PHP setting:
upload_max_filesize
Memory Limit
Controls how much memory PHP can use while processing WordPress operations.
Common PHP setting:
memory_limit
Both settings may need adjustment depending on your website.
