What ReFile does
Writing good prompts
ReFile reads intent well, but specifics get you the right result on the first try — and a first-try success is the only kind that doesn't make you wait.
Be concrete about the result
Vague
“compress this video”
Specific
“Compress this MP4 to under 8 MB at 720p, H.264, keep audio at 96 kbps.”
Helpful details: target size, resolution, codec, bitrate, frame rate, quality, output format.
Reference files by what they are
With multiple files, describe them rather than guessing filenames: “merge these PDFs in order”, “watermark every image bottom-right”. To pin one exact file, type @ and choose it.
You can name the tool (optional)
ReFile picks the right tool automatically. But if you know what you want, say it — “use ffmpeg”, “compress with Ghostscript at screen quality”. Explicit tool hints take priority.
Words ReFile interprets like a human
- “black & white” / “monochrome” → grayscale (not 1-bit), unless you say “1-bit”, “fax”, or “dithered”
- “half the volume” / “50%” → understood correctly as a multiplier
- “smaller” after a conversion → it compresses the previous output
Follow-ups chain automatically
After a result, “now make it grayscale” or “to webp” reuses the previous output as the new input — no need to re-upload.
