How to make your photo look like an old TV

Getting a convincing result is mostly about starting from the right reference point, then nudging sliders instead of maxing them out:

1
Upload a photo
Drag and drop it onto the screen or use the Upload image button. Photos with clear highlights and shadows show the phosphor glow and scanlines best.
2
Pick a starting preset
NTSC/PAL/Soviet SECAM emulate broadcast colour TVs, P31/P26/P4 emulate monochrome terminal and monitor phosphors, HDTV 1080i emulates a modern interlaced CRT, try and around see if it matches the era or device you're going for..
3
Fine-tune, don't max out
Real CRTs were subtle. Small adjustments to interlace, glow, jitter and noise read as authentic; pushing every slider to the end can read as a cheap filter. That said, moving a slider to max is a way to learn what it does, push it up to see the effect clearly, then dial it back down to a realistic level.
4
Check interlace and persistence
Interlace comb artifacts look right on video-sourced or motion content, but can read as wrong on a still photo shot with a modern camera, dial it back for stills. Persistence emulates phosphor afterglow, adding a soft ghost trail behind bright highlights, and it can look good on stills too, just watch that it doesn't get so strong it smears detail.
5
Pick an output size and save
Use the size selector above the screen — from Small up to X-large (3×) — then hit Save PNG to download the full-size, full-resolution converted image straight to your device.

Everything above happens entirely inside your browser. There's no upload, no server processing and no account your photo never leaves your device, and you can download the converted image in whatever size you need.

About interlacing

Interlacing was how CRTs avoided flicker without doubling bandwidth. Instead of drawing all lines top-to-bottom in one pass, an interlaced CRT drew two fields per frame: odd-numbered lines first, then even-numbered lines. At 25 fps (PAL) this meant 50 field refreshes per second — fast enough to appear smooth to the eye.

On still images interlacing is invisible. On moving subjects, the two fields captured slightly different moments in time — producing the characteristic comb effect of horizontal teeth along motion edges. The converter simulates this by dimming alternating scan lines, with higher values adding brightness variation between odd and even rows.

At low values (0–20) it adds a subtle shimmer that makes images feel alive. At high values (60+) the comb structure is clearly visible — wrong on a still image, but authentic on video-sourced content. The Soviet and HDTV 1080i presets have high interlace enabled by default for period-accurate results.

Common questions

Is the CRT converter free?

Yes. It's completely free, with no account, no sign-up and no watermark on the exported PNG.

Are my photos uploaded anywhere?

No. All processing happens in your browser using an HTML5 canvas. Your image never leaves your device and nothing is sent to a server.

Can I use it for game screenshots or YouTube thumbnails?

Yes. It works on any image — game screenshots, thumbnails, album art, avatars and posters. Export at up to 3× resolution so the result stays sharp when scaled.
