BG Remover Online - Remove video backgrounds with real transparent WebM

BG Remover Online removes video backgrounds and exports real-alpha WebM or ProRes 4444 for overlays and editing. It also turns photos into transparent PNGs. Upload a clip (up to 60 seconds/200 MB), preview the cutout against different backdrops, and download a file with actual transparency—not a checkerboard baked into pixels. New Google sign-ins receive 5 free credits (about 5 seconds of video); original audio is not retained. Fine edges may need review.

EditableImage - Turn flat images into editable PPTX, Draw.io and PSD

EditableImage turns flat images into files you can actually edit: PowerPoint slides with native objects, Draw.io diagrams with connected nodes, layered PSDs, and formatted text. Upload a screenshot, diagram, or poster, compare the reconstructed result with the original, make changes online, and export. Built for assets whose source files are lost or unavailable. New accounts get 10 free credits after Google sign-in; complex charts and exact fonts still need review.

WebsiteReady - Find launch blockers before Google and users do

WebsiteReady checks your launch page before you promote it. Paste a public URL and get a GO, CONDITIONAL GO, NEEDS REVIEW, or NO-GO report with P0/P1/P2 issues, evidence, and developer-ready fix prompts. It checks crawlability, SEO basics, trust pages, broken launch signals, sitemap/robots issues, analytics hints, security headers, and AI discovery readiness including llms.txt and AI crawler policy.
