Frequently Asked Questions
What is a CRT effect?
A CRT effect simulates the look of old cathode ray tube monitors and TVs. It adds characteristic visual elements like horizontal scanlines, RGB color fringing (chromatic aberration), barrel distortion from curved glass, phosphor glow, static noise, and edge vignetting to give images an authentic retro appearance.
What do the different settings control?
Scanline Intensity and Thickness control the horizontal dark lines. RGB Offset creates chromatic aberration by separating color channels. Curvature adds barrel distortion like a curved screen. Glow/Bloom simulates phosphor light bleed. Noise adds static grain. Vignette darkens the edges. Brightness Boost compensates for the overall darkening from scanlines.
What settings work best for a subtle retro look?
For a subtle effect, try lower scanline intensity (20-30), minimal RGB offset (1-2), light curvature (10-15), and moderate glow (15-25). Keep noise low (5-10) and vignette moderate (20-30). The default settings are already tuned for a balanced retro look.
What settings create a strong vintage TV look?
For a dramatic CRT TV effect, increase scanline intensity (60-80) with thicker lines (3-4), boost RGB offset (5-8), add more curvature (30-50), and increase noise (25-40). Higher vignette (40-60) and glow (30-50) complete the old-TV aesthetic.
What image formats are supported?
You can apply the CRT effect to images in AVIF, Animated PNG (APNG), BMP, GIF, HEIC/HEIF, ICO (Icon), JPE, JPG, JPG (JPEG), MP4 (Video), PBM, PGM, PNG, PNG 24-bit, PNG 32-bit, PNG 8-bit, PNM, PPM, PSD, RAW formats (CR2, CR3, NEF, ARW, DNG, ORF, RAF, etc.), SVG, TGA (Targa), TIFF, WebP, XCF. Output formats include AVIF, BMP, GIF, JPG (JPEG), PNG, SVG, TIFF, WebP.
Are my photos safe?
Absolutely! All processing happens locally in your browser using Canvas technology. Your images are never uploaded to any server — they stay completely private on your device.
Can I apply the CRT effect to multiple images at once?
Yes! Upload multiple images, preview the CRT effect, and download them all individually or as a ZIP file. The same CRT settings are applied to all images simultaneously.
Is there a file size or quantity limit?
No, there are no file size or quantity restrictions. All processing happens locally in your browser, so larger files or batches may take longer depending on your device's performance.
