One of the most common WordPress problems is the inability to add photos and videos to the media library. When it arises, a user sees the HTTP error message displayed next to the name of the file they’ve been trying to upload. Since you’ve landed on this page, you must be looking for ways to fix this issue.
The good news is that there are quite a few solutions, and we discuss some of them in this post. First, though, let’s talk about why you see this error at all.
This is a generic error that occurs when your image or video does not meet the technical requirements of the WordPress media library. The latter was created to make things simple for users to manage their online media. However, the library requires strict adherence to its specifications. Otherwise, it kicks back an error while you are uploading a file.
The http error is hard to diagnose because WordPress can, in general, be vague about what causes problems. The http error itself does not always tell you exactly why the uploading of a photo or video has suddenly stopped. There can be multiple explanations, including these:
- A file name with invalid characters
- An excessively large file size
- An unsupported file format.
Whatever the reason, there are some easy fixes available. Let’s look into these next.
The easiest way to fix the http error in WordPress is to refresh the page or clear your browser cache. Whenever you upload new files to a server, problems can arise both on your end and on the server side. You need to ensure that any conflicting cache memory or connection issues are removed.
To do this, access your browser settings and clear all browsing history and data. How you do that depends on a specific page viewer. The screenshot above shows the corresponding dialog window for Mozilla Firefox.
There are many browsers available for free. Chances are one of them will not generate the same error. So if you cannot upload media in one browser, try a different one and see if that solves the problem.
WordPress limits the maximum size of files you can add to the media library. You could be getting the http error when uploading an image or video because its size can be outside the 2MB to 150MB range.
The best thing you can do is resize your photo or video using compression software like WinRaR or an online tool like tinypng.com. For a brief review of such tools, scroll down to Bonus Section #1 below.
There are also plenty of plugins that will automatically reduce the size of the media you’re uploading. Visit the Plugins section in your WordPress dashboard and type in something like “compress pictures.” You’ll see a lot of valuable tools like the ones in this screenshot.
In Bonus Section #2, you will find a rundown of some noteworthy WordPress plugins for image size reduction.
WordPress won’t let you rename a file that you have already uploaded. That said, you can always rename the original file and then try to upload it again. Avoid special characters (#, $, !, ~, *, etc.) that violate the WordPress file naming convention. Be sure to only use letters, numbers, and a hyphen if you need to. Something like “happy-file-1.jpg” works well.
WordPress can sometimes behave unpredictably if you are performing a lot of updates or uploads at once. If you continue to get the WordPress http error, try stopping and waiting for a few minutes. The problem could be on the server side. Waiting allows the server to reset its own cache. Try uploading your images after about 3-5 minutes and see if that does the trick.
Most plugins are designed by independent people using open-source software. These plugins can make your website more functional. Yet, they might not have been developed by professional companies that know how to resolve cross-platform conflicts. If you are still experiencing the http error, try deactivating all the plugins on your WordPress site temporarily.
- Log into your admin area.
- Select Plugins on the left.
- Select the plugins you want to deactivate by ticking the corresponding checkboxes.
- Click on the dropdown menu under Plugins at the top of the page and select the Deactivate option.
- Click the Apply button.
This should remove any conflicts that could be interrupting your uploads. If this solution works, be sure to re-activate your plugins after you are done uploading your new media.
As a last resort, you may want to contact your WordPress hosting provider. The problem might be on their side. For example, they might have just rolled out an update precisely at the moment you were trying to upload an image. That prevented the server from responding in time.
This wraps it up. If you encounter the WordPress http error when uploading a file to the media library, don’t panic. Try one of the methods we have described above. In most cases, you will be able to solve the problem without outside help.

A Review of Some Popular Online Image Compression Tools
JPEG Optimizer lets you decrease the size of an image before optimizing it. This makes loading time much shorter.
You can specify how much you want an image to shrink by selecting a level between 0 and 99, with 65 being the most well-balanced option. The tool doesn’t work with image formats other than JPEG.
- Several user-specified compression levels
- Image size can be reduced prior to optimization
- Works with the JPEG format only
If you’re a photographer or designer, you might need to change the size of a large number of images at once. That’s where the free online tool CompressNow truly shines. Its drag-and-drop feature lets you include 10 images for optimization in one go.
The tool also allows you to set a compression level, but only for an entire batch of images. If you want to specify a compression level for one file, upload this file only.
- Supports the most widespread image formats: JPG, JPEG, GIF, and PNG
- You can work with a group of images in bulk
- One image can weigh up to 9MB
- You can only set a compression level for a group of images
- The tool doesn’t retain the PNG and GIF transparency
If you’re not completely new to the world of web development and design, you must have heard of TinyPNG. This is one of the veterans among online image compression tools. As such, it probably has more features and a larger ecosystem than most similar size-reducers.
The tool’s primary focus is PNG. This is the only format that stores partially transparent images. At the same time, these files can weigh a ton. The tool shrinks PNG images while ensuring excellent quality.
Apart from PNGs, you can optimize images in the JPEG and WEBP formats.
- Works with the PNG, JPEG, and WEBP formats
- The pro version allows you to upload up to 20 images, each exceeding 5MB
- The free version only allows uploading images of up to 5MB
This online tool targets two of the most popular image formats — JPEG and PNG. It allows you to shrink an image to the maximum smallest size, at the same time ensuring the best quality.
Unlike many other image optimizers, Optimizilla provides a comparison option. That is, you can see an image prior to optimization and after it in the same window.
A slider lets you set a compression level to reduce an image size without affecting quality. You can identify the moment an image starts looking blurry by watching the transformation process in real time.
Another exciting feature of Optimizilla is the ability to work with images in batches. Drag and drop up to 20 images. Then either set a compression level for the entire batch or go over image by image setting a specific level for each one.
- A handy before-after comparison feature
- Allows you to work with images in bulk, setting a specific compression level for each image
- Reduces an image size to the maximum possible level while retaining the best quality
- Works with the PNG and JPEG formats only
This tool works with a wide range of image formats — JPG, PNG, GIF, BMP, and PSD. For each image you upload, you can set a compression level of up to 100.
The most noteworthy feature of Resize Photos is the ability to give an image a particular visual effect. Among the rest, the options include:
- Rounded corners
- A large variety of supported formats
- Ability to apply specific visual effects to images
- No option for resizing images in bulk
