everything the engine does

png

screenshot render

Any HTML string → a pixel-perfect PNG. Custom viewport, animation-frame seeking, optional response caching.

pdf · v1 + v2

print-ready pdf

Chromium for quick PDFs, or WeasyPrint for real print: CMYK, ICC profiles, bleed, trim marks & PDF/X-4.

mp4 · gif

video capture

Record animated HTML deterministically, frame by frame. Set FPS, duration & resolution — FFmpeg encodes server-side.

rembg

background removal

Upload an image, get a clean transparent PNG back. u2net model, tunable force levels, edge refinement.

pdf → json

document parsing

Extract text from PDFs, or let Claude detect the type & return structured JSON — invoices, contracts, forms.

yt · x

url → mp4

Pull video straight from YouTube or X/Twitter via yt-dlp. Pick a quality, or just grab the audio track.
