MultiHandler Tools
Free creator tools that run entirely in your browser. Your files, captions and keywords are never uploaded — everything happens on your own device, on this page.
🖼️ Remove Background — Photo
Remove the background from a photo or thumbnail and download a transparent PNG. Best with portraits and product shots. The first run downloads a small AI model (about 40 MB) — after that it works instantly.
🎬 Video Toolkit — your own video file
Work on a video file from your own device: extract its audio as MP3, trim a clip, make a short GIF, or compress it for upload. Processing happens in your browser — big files (over ~200 MB) may be slow. The first run loads the video engine (about 25 MB).
🔄 Online Converter
Convert a file from your own device — video and audio to MP4, MP3, M4A or WAV, and images to PNG, JPG or WebP. Everything converts in your browser; nothing is uploaded to a server.
✍️ Title & Hashtag Helper
📝 Caption Studio
Write your caption once and see it checked live against every platform's limits — then copy it into the MultiHandler app.
⏰ Best Time to Post
General guidance based on widely published creator studies. Your own audience analytics (shown in the MultiHandler app) always win over general advice.
