Make PNG screenshots, graphics and logos smaller by resizing them, or convert to WebP for files that are often 70–90% smaller. Your files never leave your device.
Output stays PNG by default to preserve transparency. Change the format to WebP if you need the smallest file and the site accepts it.

PNG is lossless: every pixel is stored exactly, so there is no quality slider to lower. The reliable ways to shrink a PNG are fewer pixels (resize) or a different format.
WebP supports transparency like PNG but uses far more efficient compression. JPEG is smallest for photos but does not support transparency; transparent areas become white.
JPEG, PNG, or WebP. Batch as many as you like, all at once.
Your browser does the resizing and compressing. Nothing is transmitted.
Grab files one at a time, or everything together as a zip.
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.
