If the original is clear, check whether the page is displaying a too-small image variant or an aggressively compressed version. If the original is already degraded, use the best clean source you have and export a new copy; sharpening, upscaling, or converting formats cannot reliably restore detail that has been discarded.
1. Find where the image becomes blurry
Compare the image you see on the page with the original file you uploaded, if you still have it. Open both at a similar viewing size. If the original is clear but the website copy is not, the problem is likely in the image variant or processing path used by the site. WordPress can process images in the browser and on the server, so the file on the page may have passed through more than one step.
- The original and site image are both soft: start with a better source file. Exporting another copy of an already degraded image will not bring back missing detail.
- The original is clear, but the site image is soft: inspect the selected image size, optimization settings, theme display, and any CDN or image-processing service that may be changing the file.
- Only edges or fine textures look blocky, smeared, or mottled: compression may be too aggressive. Compare a fresh export with the source.
- The image looks generally soft after being resized: resizing may have softened it. Check the result at the size it is actually displayed before making a restrained sharpening adjustment.
WordPress.com Support’s blurry-image troubleshooting guidance puts the source-file limitation plainly: “You can size down a high-quality image file, but you can’t size up a low-quality image file with good results.”
2. Check the image’s pixel dimensions against its display size
An image can look blurry when the page enlarges a file with too few pixels for the space it occupies. Check the dimensions of the actual image file being served, then compare them with the dimensions at which it appears on the page. In WordPress, also check the image size selected in the block settings: a smaller thumbnail or responsive variant may be used where a larger one is needed.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
If the image is being enlarged, choose a larger available variant or replace it with a higher-quality, larger source. WordPress.com does not prescribe one image dimension for every use; the appropriate size depends on the placement and display. Avoid enlarging a small, low-quality file and expecting it to gain real detail.
3. Re-export a compressed image from the best source
JPEG compression is lossy: saving a photo as JPEG removes some image information. If compression artifacts are the problem, return to the highest-quality original available and export a fresh copy using less aggressive compression. Do not repeatedly recompress a degraded export when a better source exists.

There is no single JPEG quality number that works best for every image. Make a test export and compare it side by side with the source at the intended display size. Judge both visible fidelity and file size; a larger file may preserve more detail, but the trade-off depends on the image and its use. WordPress’s image-quality guidance recommends inspecting resized results because resizing can also make an image slightly soft.
4. Inspect the actual WordPress image pipeline
Do not assume that the file you uploaded is the file visitors see. WordPress’s current developer documentation describes browser-side image processing—including compression, resizing, conversion, rotation, and thumbnail generation—and quality controls shared with server-side processing. A theme, optimization plugin, or CDN may also affect which output is delivered.

- Identify the served file. Open or download the image used by the page rather than comparing only the upload with the page preview.
- Compare the upload, generated variants, and served file. Look for a smaller variant being enlarged, visible compression artifacts, or a format conversion that coincides with the quality change.
- Review the processing settings. Check any optimizer’s quality, resize, conversion, and original-backup options. Change one setting at a time and test with a copy so you can identify which step affects the result.
- Verify after changing settings. Inspect the new served file at its actual display size. A setting change is not a fix unless the delivered image looks better for the intended use.
For WordPress JPEG handling, jpeg_quality is a documented control; the client-side processing guide also references wp_editor_set_quality. Which control applies depends on the image editor and processing path. A single setting should not be assumed to govern every generated output.
If an upload fails with a transcoding error, WordPress’s processing guide lists unsupported or corrupt input as possible causes. The guide’s troubleshooting section lists JPEG, PNG, WebP, AVIF, GIF, and HEIC among supported formats; actual support can depend on the processing environment.

5. Use sharpening only for slight softness after resizing
If the source is clean and the only change is mild softness from resizing, a modest sharpening adjustment may improve the appearance. Judge it at the image’s real display size. Too much sharpening can create bright or dark halos around edges and make noise or compression artifacts more obvious.
Sharpening is a finishing adjustment, not a way to reconstruct detail removed by compression or absent from a small source. Upscaling and switching formats have the same limitation: neither can guarantee recovery of discarded information.

6. Treat WebP as a format choice, not a repair
Changing a blurry image to WebP does not restore its detail. WordPress Core reported in 2022 that its generated WebP files were about 30% smaller on average than JPEG files at the same visual quality. That was an average reported by the project, not a guaranteed saving for an individual image, and it does not show that format conversion repairs blur. Compare the actual output’s fidelity and file size before choosing a format.
7. Preserve a clean original for future exports
Keep an untouched, high-quality source where possible. It gives you a better starting point if you need a different size, compression level, or format later. Some WordPress optimization tools offer original backups and re-optimization options; for example, Imagify documents backup and re-optimization features. Such features can help manage image versions and settings, but they cannot reconstruct detail that was already discarded if no clean original remains.
