FAQ
Common questions,
honest answers.
- Is DocsMe really free? What's the catch?
- There is no catch. Every tool on DocsMe is 100% free, permanently. No freemium tricks, no 'you've used your 3 free exports this month' limits, and no credit card required. We built these tools because we were frustrated with paywalled alternatives.
- Do my files get uploaded to your servers?
- No. Most DocsMe tools process files entirely in your browser using WebAssembly and browser-native APIs. Your documents never leave your device. For operations that require server-side processing, files are automatically deleted immediately after your download.
- Do I need to create an account or sign up?
- Never. Open any DocsMe tool, do your work, and close the tab. There's no account to create, no email to confirm, and no profile to maintain. We don't even have a sign-up page.
- Which browsers are supported?
- All modern browsers: Chrome, Firefox, Safari, Edge, and Brave on desktop and mobile. We recommend Chrome or Edge for best performance with large PDF operations.
