// how it works

File picked

Browser receives a File object from your disk. Nothing is uploaded anywhere.

FileReader reads

The FileReader API reads the raw binary bytes into memory locally.

Base64 encoding

Binary is encoded to Base64 — ASCII-safe text, ~33% larger than original.

URL assembled

Prefixed with data:[mime];base64, — a complete, self-contained image URL.

100% client-side · no server · no storage · image never leaves your device · works offline

Privacy Policy

Effective: 1 January 2025 Last updated:

imgto64 is a free, client-side image conversion tool. This policy explains what data we collect (spoiler: almost none), how the tool works, and your rights.

The short version

Your images never leave your device. imgto64 performs all conversion entirely inside your browser using the built-in FileReader API. No image data, file names, or converted URLs are transmitted to any server — not ours, not anyone else's.

What we collect

We do not collect, store, or process any personal data through the tool itself. We have no user accounts, no login, and no database.

When you visit imgto64.co.uk, the site is served by Vercel (our hosting provider). Vercel may log standard request data including your IP address, browser type, and pages visited for the purposes of security, performance, and abuse prevention. This data is governed by Vercel's Privacy Policy and is not accessible to or controlled by imgto64.

Cookies & tracking

imgto64 does not use cookies, tracking pixels, analytics scripts, or any third-party tracking technologies. We do not fingerprint your device or monitor your behaviour on the site.

DNS for imgto64.co.uk is managed by Cloudflare. As your DNS resolver, Cloudflare may process your IP address when resolving our domain. This is governed by Cloudflare's Privacy Policy.

The only external resource loaded at runtime is Google Fonts (for the Syne and DM Mono typefaces), served from Google's servers. Any data collected in that process is governed by Google's Privacy Policy.

Your images

All image processing happens locally in your browser. The file you select is read by the browser's FileReader API, encoded to Base64, and returned to you as a data URL — entirely on your device. At no point is your image uploaded, transmitted, cached remotely, or accessible to us.

Third-party services

imgto64 does not embed any advertising, affiliate links, or social media widgets. The following third-party services are involved in delivering this site:

Vercel

Hosting & deployment

Cloudflare

DNS management

Google Fonts

Typeface delivery

Children's privacy

imgto64 is a general-purpose developer tool not directed at children. We do not knowingly collect data from anyone under 13.

Changes to this policy

If this policy changes materially, the updated date above will reflect that. Continued use of the tool after any changes constitutes acceptance of the updated policy.
