Set the size you need, and NoUpload adjusts quality and dimensions until each image fits under it. Your files never leave your device.
For upload forms that reject anything over a fixed size. Type your limit into Target KB, or pick one of the presets below.

NoUpload encodes the image, checks the size, and lowers quality step by step until it fits. If quality alone cannot get there, it also reduces the dimensions. The result shows whether the target was met.
Sizes are measured in kibibytes (1 KB = 1,024 bytes). If a site’s limit is strict, aim a little lower, such as 95 KB for a 100 KB limit.
WebP gives the smallest files at a given quality. Use JPEG when a site does not accept WebP. PNG is lossless, so it only gets smaller by reducing dimensions; convert to JPEG or WebP for big savings.
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.
