About OmniGIF

Privacy first. Browser based. Always free.

We brought GIF conversion, effects, and frame tools directly into your browser. No server uploads, no privacy concerns — just local processing.

By Calvin Sun

Privacy by design

Unlike traditional converters that require uploads, OmniGIF processes files in your browser. Your GIFs, Live Photos, and screenshots never leave your computer.

Built for speed

Skipping the upload-process-download loop means we use your device directly. Tweaking FPS, crop, or effects and re-exporting is nearly instant.

No sign-up wall

No aggressive ads, no mandatory accounts, and no paywall for core tools. Software should respect your time, attention, and files.

The architecture of trust

How OmniGIF differs from most online GIF converters

Old school (server-side)

Files travel across the internet to a remote server. You cannot see who stores the GIF, how long it is retained, or whether it is logged.

Recommended

OmniGIF (client-side)

Files are decoded and encoded in your browser with JavaScript and WebAssembly. Private, fast, and usable after the page loads — without sending the binary to us.

Why I built this

Calvin Sun

Founder of OmniGIF

Hello, I'm Calvin Sun, an independent developer. OmniGIF started from a simple frustration in 2025.

I needed to extract frames from a GIF that included personal photos. Every online tool asked me to upload the file first. I hesitated. Who owns that server? How long do they keep the GIF? Is a private screenshot now sitting in someone else's processing queue?

Modern browsers can already decode GIF89a, encode WebP and APNG, and even run FFmpeg through WebAssembly. Your computer is powerful enough — we do not need to ship the file to a converter in the cloud. So I spent my weekends building OmniGIF: a suite of GIF tools that feel like desktop software, but run entirely in the browser. The mission is simple: convert, edit, and inspect animations without compromising privacy.
