How to Reduce WordPress Website Size & Free Up Hosting Disk Space
Hosting says "disk quota exceeded"? Backups failing or the site getting slower? Learn why your WordPress website grows so large, how to shrink it safely, and how an expert can cut its size by 50% or more without breaking anything.

- Old backups, unused image thumbnails and log files cause most WordPress bloat.
- Check your size in Tools → Site Health → Info or cPanel Disk Usage.
- Always take an off-site backup before deleting anything.
- A proper cleanup usually reduces site size by 30–70% and makes the site faster.
A WordPress website rarely starts big. A fresh install is only around 60–80 MB. But after a year or two of uploads, plugin tests, backups and updates, many sites grow to 5 GB, 10 GB or even 50 GB. Then hosting gets expensive, backups fail and migrations become a nightmare.
I am Md Juwel Rana, a WordPress developer at Web Relife. I have cleaned up and reduced the size of WordPress websites for clients in the United States, Europe and Asia. In this guide I share the same process I use, so you can do it yourself or hire me to do it safely for you.
Why Is My WordPress Website So Large?
In almost every site I audit, 80% of the wasted space comes from the same few places:
| What takes space | Where it lives | How bad it gets |
|---|---|---|
| Old backup files (UpdraftPlus, All-in-One WP Migration, Duplicator, BackupBuddy) | /wp-content/updraft, /ai1wm-backups, /backups | Often 2–20 GB alone |
| Unused image thumbnails generated by themes & plugins | /wp-content/uploads | One image can create 10–20 copies |
| Large uncompressed images (PNG, full-size JPG) | /wp-content/uploads | Photos of 3–8 MB each |
| Cache & log files | /wp-content/cache, error_log, debug.log | Logs can reach several GB |
| Inactive plugins & themes | /wp-content/plugins, /themes | Hundreds of MB |
| Database bloat (revisions, transients, spam, orphaned data) | MySQL database | Can slow every page load |
| Email accounts on the same hosting | cPanel mail folders | Silently eats your quota |
Signs Your Hosting Disk Space Is Running Out
- Your host sends a "disk quota exceeded" or "account over limit" warning.
- You cannot upload images: "Unable to create directory" or "HTTP error" in the media library.
- Plugin and WordPress updates fail halfway.
- Backups stop running or are incomplete.
- Emails on your domain stop arriving.
- Your site migration keeps failing because the file is too big.
- Your host is pushing you to upgrade to a more expensive plan.
How to Check Your WordPress Website Size
Method 1: WordPress Site Health
Go to Tools → Site Health → Info → Directories and Sizes. You will see the size of uploads, themes, plugins and the database. (See the official WordPress Site Health guide.)
Method 2: cPanel Disk Usage
In cPanel open Disk Usage. It shows which folders are the biggest, including mail and backups outside WordPress.
Method 3: SSH (for developers)
10 Proven Ways to Reduce WordPress Website Size
Always take one fresh, off-site backup first. Then work through these steps:
Delete old backups on the server
Download what you need, store it in Google Drive, Dropbox or S3, then remove old backup archives from hosting.
Remove unused thumbnail sizes
Disable image sizes your theme does not use and delete the extra copies already generated.
Compress & convert images to WebP
Lossless or smart compression with WebP/AVIF can cut image size by 30–80% with no visible quality loss.
Delete unused media files
Find images not attached to any post, page or product and remove them carefully.
Remove inactive plugins & themes
Keep one default theme as fallback. Everything inactive is dead weight and a security risk.
Clear cache & log files
Huge error_log and debug.log files are common. Clear them and fix the errors that create them.
Optimize the database
Remove post revisions, expired transients, spam comments, orphaned meta, leftover plugin tables and heavy autoloaded options.
Limit post revisions
Add define('WP_POST_REVISIONS', 5); to wp-config.php so the database stays lean.
Offload large files
Move videos to YouTube/Vimeo and large media to a CDN or cloud storage.
Clean up email storage
Old mailboxes on the same hosting often use gigabytes. Archive or move email to a dedicated provider. See my guide to free up hosting space.
Mistakes That Can Break Your Site
- Deleting files from /uploads by guesswork. Images used by page builders (Elementor, Divi, WPBakery) are often not "attached" and look unused.
- Running aggressive database cleaners without a backup. Some delete WooCommerce data or settings.
- Removing the only backup. Always keep one verified copy off the server.
- Over-compressing images. Product photos can become blurry and hurt sales.
- Installing five cleanup plugins. They add more bloat and can conflict with each other.
If you are not 100% sure what a file or table does, it is safer to let an experienced developer handle it.
How to Stop Your WordPress Site From Growing Again
Once you reduce WordPress website size, a few simple settings keep it small for years:
- Store backups off-site only. Send UpdraftPlus or your host's backups to Google Drive, Dropbox or Amazon S3 and keep only the last 3–5 copies.
- Resize images before upload. Most blog images never need to be wider than 1920px. Set a max upload size in your image optimizer.
- Serve WebP automatically. New uploads are converted and compressed the moment you add them.
- Limit revisions and empty trash faster. Add
define('EMPTY_TRASH_DAYS', 7);to wp-config.php. - Turn off debug logging on live sites. Keep
WP_DEBUG_LOGdisabled unless you are troubleshooting. - Schedule a monthly database cleanup. Five minutes a month prevents gigabytes of bloat.
- Review plugins every quarter. If a plugin is not used, delete it, do not just deactivate it.
DIY vs Hiring a WordPress Expert
| Factor | Do it yourself | Hire an expert |
|---|---|---|
| Cost | Free (plus your time) | One-time fixed price |
| Time needed | Several hours to days | Done in 1–3 days |
| Risk of breaking the site | Medium to high | Very low, with full backup |
| Page-builder & WooCommerce safe | Hard to verify | Checked manually |
| Before/after report | No | Yes |
If your site is small and you are comfortable with backups, the steps above are enough. If it is a business website, a WooCommerce store or your disk is already full, hiring a professional is the faster and safer choice.
