How image resizing works
OnlyFiles uses the Canvas API to resize images entirely in your browser. Your image is drawn onto a canvas at your target dimensions, then exported as a new file. No data is ever sent to a server.
Your files never leave your device
All resizing happens locally in your browser tab. You can disconnect from the internet after the page loads — the tool still works. Nothing is uploaded.
