Image Compressor
Resize and compress JPEG, PNG, and WebP images entirely in your browser, with no upload step and no size limit beyond your own device's memory. Your files never leave your device.
Built for shrinking photos before you email them, hitting a CMS or marketplace's upload size limit, or batch-compressing a folder of images for the web without installing anything.

Your browser does the resizing and compressing. Nothing is transmitted.

Grab files one at a time, or everything together as a zip.
Most file tools send your files to someone else's server first. NoUpload doesn't.
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.
- Your files never leave your device
- No account, sign-in, or email required
- Analytics events record only which tool and page were used
- No server-side file processing path
Don’t take our word for it. Check.
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.
- Open the Network panel. Press F12 (Windows/Linux) or ⌥⌘I (Mac) and choose the Network tab.
- Process a file. Add an image and run any tool, then download the result.
- Read the requests. You will see page assets and small anonymous analytics pings. No request carries your image.
Or go further: load the page, switch off Wi-Fi, and use the tool. Processing still works, because it never needed a server.
Privacy & terms
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.
