Most tools run entirely in your browser using WebAssembly and native APIs. Your files stay on your device unless a specific job requires server assistance.

Fast & Free

No queues, no subscriptions for everyday tasks. Start processing immediately with generous free limits for personal and professional use.

Cross-platform

Works on Windows, macOS, Linux, iOS, and Android browsers. Need offline or batch workflows? Continue in the Seer app ecosystem.

Privacy by Design

We do not sell your files or use them for training. Clear upload boundaries, automatic deletion after server jobs, and transparent analytics only.

Privacy Promise

Your files deserve better than “trust us”

SeerKits is built on a simple principle: process locally whenever possible, be transparent when it is not, and never keep your files longer than necessary. No account is required for web tools, and we never sell your data.

Read our Privacy Promise

Local by default

When your browser supports the job, processing happens entirely on your device — nothing is uploaded.

Clear upload boundaries

Server-assisted tools show an explicit notice before any upload. You always know where your file goes.

Automatic deletion

Files used for server processing are deleted immediately after the job completes. We do not retain copies.

Seer App Ecosystem

Go beyond the browser

The Seer app family extends every SeerKits category with larger file limits, batch processing, offline workflows, and pro-grade controls — same privacy-first approach, more headroom.

Frequently Asked Questions

Common questions about SeerKits tools and privacy

Is SeerKits really free?

Yes. All web tools are free for everyday file sizes with no account required. The Seer mobile and desktop apps offer expanded limits, batch processing, and advanced options for power users.

Do you upload my files to a server?

Most tools process files locally in your browser. For jobs that require server assistance (such as certain codec conversions), you will see a clear notice before any upload. Server-processed files are deleted immediately after the job completes.

What file size limits apply on the web?

Each tool has its own free tier limit, typically up to 200 MB per file. Check the tool page for specific limits. For larger files or batch jobs, download the relevant Seer app.

Do I need to create an account?

No account is required to use any web tool. Account features will be available in a future update for saving preferences and accessing cross-device history.

Which browsers are supported?

SeerKits works best on the latest versions of Chrome, Firefox, Safari, and Edge. Local processing requires a modern browser with WebAssembly support.

Can I use SeerKits on mobile?

Yes. The website is mobile-friendly, and dedicated Seer apps for iOS and Android offer offline processing, larger file support, and batch workflows.

How is SeerKits different from other online converters?

We prioritize local-first processing, transparent privacy boundaries, and no forced sign-ups. You see exactly how each tool handles your file before you start.

What analytics do you collect?

We use Google Analytics 4 to understand aggregate usage patterns — page views, tool starts, and completion rates. We do not track file contents or personal file metadata.
