What Cowslator can do
Attach files or a folder in chat and request an operation. Processing happens locally; supported outputs depend on the format and browser.
PDFs
Merge, split and compress; extract, remove, reorder or rotate pages; extract text and read scans with English/Portuguese OCR. Try “Compress PDF” or “Extract pages 2-4”. Strong compression can rasterize pages; its report identifies the changes.
Images
Resize, crop, rotate, flip, compress and convert PNG, JPEG, WebP and browser-supported AVIF; read image text with OCR. Try “Resize to 1600px and convert to WebP”.
Documents and search
Summarize TXT/PDF with your selected SmolLM2 model. Save MiniLM embeddings in IndexedDB and search contextual matches with page and line references. Try “Semantic search payment”. Lines refer to extracted text.
Audio and video
Transcribe with local Whisper; extract audio; convert, split and join recordings; combine separate audio/video; resize videos; add SRT/VTT tracks or burn video subtitles. Subtitled audio uses MKA. Try “Extract audio to MP3” or “Split every 30 seconds”.
Formats and packaging
Audio: MP3, WAV, M4A/AAC, FLAC, OGG, Opus, AIFF and WMA. Video: MP4, MOV, WebM, MKV, AVI and MPEG. Convert text/data among TXT, PDF, DOCX, RTF, Markdown, HTML and CSV/JSON, including text ↔ PDF. Package files and results as ZIP. Document conversion preserves text/data rather than complex layout.
