❓ FAQ

Where are my images stored?

Entirely on your device. DocFit never uploads your photos anywhere — all processing happens in your browser.

Can I paste an image instead of uploading?

Yes. Copy any image to your clipboard, then press Ctrl + V (or paste on mobile) while a tool is on screen. The image is loaded instantly.

What is the Copy button for?

After processing, click Copy to put the result on your clipboard. You can then paste it directly into a form, WhatsApp, email or document — no file saving needed.

Why doesn't Copy work on my phone?

Clipboard access requires a secure (HTTPS) connection. On a local address it may not work — but it will work on the deployed HTTPS site.

How does DocFit remember my settings?

Your last-used width, height, KB and format are saved in your browser. Next time you open a tool, they're pre-filled.

Why does the download filename look odd (like docfit-photo-1727…)?

It includes a timestamp so files don't collide. You can rename it after downloading.

Can I use DocFit offline?

Yes — after the page loads once, all tools work without internet. Files stay on your device.

Does it work on mobile?

Yes. DocFit is designed to work on phones, tablets and computers.
