Most modern WordPress themes display featured images well at 1200 × 675 (16:9). Crop your image to that size, plus a matching 1200 × 630 social preview. Your photo never leaves your device.
WordPress featured: 1200 × 675 px JPEG. This is the platform’s recommended upload size. Keep faces and text away from the edges, because some apps crop the preview. Need different settings? Use one of My sizes.
Your photo stays in this tab. Only preset settings are saved in this browser.
WordPress itself has no single featured image size; your theme decides. 1200 × 675 is a safe default for 16:9 layouts used by most block themes. If your theme uses another ratio, check its documentation and create a custom size under My sizes.
Uploading a correctly sized image avoids WordPress generating blurry or awkwardly cropped thumbnails, and keeps pages fast.
SEO plugins use the featured image as the link preview unless you set one. Exporting a 1200 × 630 version at the same time gives you a clean preview for social shares.
JPEG, PNG or WebP. It is decoded in this tab and never uploaded.
See the whole photo with every size outlined. Mark the subject once and all sizes follow it; drag any box to adjust it.
Individually or as a ZIP, with metadata stripped from every file.
For client work, ID scans, medical documents, unreleased product shots, or anything else you do not want sitting in a stranger's storage, the safer upload is the one that never happens.
File processing runs in your browser. Google Analytics records page views and anonymous tool-usage events, but NoUpload does not send filenames, metadata values, file sizes, image blobs, or other file details as analytics data.
Anyone can claim files stay on your device. Here is how to confirm it yourself in under a minute, with tools already in your browser.
Or go further: load the page, switch off Wi-Fi, and use the tool. Processing still works, because it never needed a server.
What NoUpload does with files: image inspection, cleaning, resizing, and compression happen in your browser. Your files are not uploaded to NoUpload for processing.
What this site collects: standard page-view analytics plus anonymous usage events (a tool was opened, a file was added, processing started, an export completed) that record only the tool and page name. Google Analytics may record approximate location, device/browser type, and pages visited. NoUpload does not send filenames, image data, metadata values, file sizes, dimensions, or file counts.
Terms: NoUpload is provided free, as-is, with no warranty of any kind. Use it at your own risk.
