Frequently asked questions
Is my data safe?+

Does it work without the internet?+
Most tools work completely offline once the page has loaded. PDF tools that load from CDN need an initial connection.
Can I use this for government applications?+
Yes. We specifically design our tools to meet the requirements of official portals and exam forms.
What file types are supported?+
Images (JPG, PNG, WebP, AVIF, etc.), PDFs, and various developer formats like JSON, CSV, and Markdown.
A tool failed. What now?+
First, refresh the page. If the problem persists, try a different browser or contact us via the contact page.
Are there file size limits?+
Limits depend on your device's available RAM. Most modern devices handle files up to several hundred megabytes.
