Why featured image size matters
Every WordPress theme expects a specific featured image size, so it's worth taking a moment to resize an image for WordPress rather than uploading it as-is — themes crop to a fixed aspect ratio, and if your upload doesn't match, faces, product edges, or key details can get cut off automatically. Uploading an oversized image also slows your page load time, which affects both user experience and search ranking.
How it works
Step 1
Upload
Pick any image — portrait, landscape, any size. It stays on your device.
Step 2
Resize & Convert
The tool crops to 1200×675 and encodes WebP plus a JPEG fallback.
Step 3
Download
Grab either file straight from your browser — no upload step.
Frequently asked questions
- What size does WordPress use for featured images?
- Most modern WordPress themes use a 1200×675 pixel image (a 16:9 ratio) for the featured image shown at the top of posts and in blog listings. Some themes vary slightly, so check your theme's documentation if pixel-perfect sizing matters.
- Should I use WebP or JPEG for my featured image?
- WebP is smaller at the same visual quality and is supported by all current browsers. This tool gives you both — use WebP as your primary upload, and keep the JPEG as a fallback if your theme or plugin requires it.
- Why is my image cropped differently than I expected?
- The tool crops from the center of your image to fit the 1200×675 ratio. If your subject isn't centered, crop or reframe the original image before uploading for best results.
- Is PublishFit free to use?
- Yes. There's no account, no subscription, and no limit on how many images you can resize — PublishFit is free to use, on this tool and every other one on the site.
- Can I use this on my phone?
- Yes. PublishFit works in any modern mobile browser — tap to upload a photo from your camera roll or files, and download both the WebP and JPEG versions straight to your phone.
