Pixel-perfect screen sharing.
Why text clarity matters for code.

If your viewer can’t read your code, you’re not collaborating — you’re narrating. Here’s why most screen sharing tools blur text and what to look for instead.

How video compression hurts text

Codecs are optimized for faces, not fonts.

H.264 and VP9 were designed for video conferencing: smooth gradients, skin tones, movement. They handle natural imagery well. But sharp monospace characters at 12px are their worst case.

Dark themes amplify the problem.

Light text on a dark background creates high-contrast edges. Lossy codecs treat these sharp transitions as noise to be smoothed away. The result: characters blur together and syntax highlighting loses its meaning.

Every scaling step destroys detail.

Retina display captured at 2x, encoded as video, decoded on the viewer’s machine, scaled to fit their window. Each step in the pipeline loses the fine detail that makes text readable.

What pixel-perfect actually means

No lossy re-encoding.

Instead of running your screen through a video codec, pixel-perfect tools capture and transmit raw pixels. The viewer sees exactly what you see: every character, every pixel of syntax highlighting.

Any font size, any theme.

10px on a dark background or 14px on light mode, it doesn’t matter. Without lossy compression, text renders exactly as intended regardless of your editor setup.

Clarity over smoothness.

On slower connections, smart tools reduce frame rate before reducing resolution. A sharp frame every 200ms is far more useful than a blurry frame every 33ms when you’re reading code.

Frequently asked questions

Does "optimize for text" in Zoom fix it?

It helps, but it's a workaround. You're still running text through a codec that wasn't designed for it. Dark themes, ligatures, and small font sizes still produce visible artifacts.

Does pixel-perfect sharing use more bandwidth?

Not necessarily. Code screens change infrequently — you type a line, pause, think, type another. Smart tools only transmit what changed, which is often very little. Static screens use almost no bandwidth.

Is native better than browser-based?

Generally yes. Native apps access screen capture APIs directly, which means lower CPU usage, lower latency, and better quality. Browser-based tools add a layer of abstraction that typically hurts performance.

Does it work with Retina displays?

With native HiDPI support, yes. The tool captures at your display's full resolution without the downscaling artifacts that plague general-purpose screen sharing tools.
