Why 500KB is a practical upload target
Uploads often fail because a file may be acceptable in one system but too large for another in the same workflow. You might attach an image to email successfully, then fail when submitting that same file to a CRM, support desk, or form builder. Many tools show only generic errors, so the real size issue is easy to miss.
Typical limits vary, but 500KB is a practical target for web forms, profile images, CMS media fields, and routine email attachments where speed matters. It keeps pages lighter and reduces transfer time on mobile connections. Large camera photos can be several megabytes, so reducing them to about 500KB improves compatibility across platforms.
Compression helps by removing extra data that does not materially improve how the image looks on screen. The result is faster uploads, smaller attachments, and less friction for recipients. Privacy remains intact because this tool processes files locally in your browser. Nothing is uploaded, nothing is stored remotely, and your image stays under your control.
