Sign PDFs by touch and speed up local media work
Write on a PDF with your finger, generate English captions using available GPU support, and export video through a faster frame-based path—all while processing your files on your device.
PDFSplat: sign directly on the page
Open a PDF, choose Add signature → Draw signature on PDF (or Draw), and write with a finger, stylus, or mouse. Lift your finger between letters: the pen stays active for multiple strokes. Choose a pen color and width, or use Undo stroke to correct a mark.
On phones, the editing panel hides while drawing to leave more room for the page. Drawing captures touch gestures so the document does not scroll under your finger. Choose Done drawing to resume scrolling, then Save as → PDF to keep the signature and annotations in a new copy. Typed and uploaded signatures remain available.
Capture an open tab or window to PDF
Choose Capture to PDF → Choose tab or window in a supported desktop browser. Share the tab or window showing your page, including a logged-in page or unpublished preview. Return here and capture a page. Scroll the source and capture again to add more pages. Only the visible area is captured; text becomes an image without OCR.
Review or remove captures, then download a PDF or add the pages to your open document. Each capture becomes one PDF page, with a limit of 20 captures at up to 2,200 pixels on the longest edge. Captures stay on your device. Automatic scrolling and a URL/print workflow are not provided. Unsupported browsers display a capture availability message.
MediaSplat and VideoSplat: GPU-assisted captions
The English subtitle generator’s Auto setting checks for usable WebGPU support. A compatible GPU can help transcribe speech and generate SRT files; an NVIDIA card is not required. Choose CPU · compatibility mode when desired. Local GGML model files continue to use the CPU engine.
If GPU processing fails, transcription retries the current audio window on CPU and retains completed progress. The interface reports the selected backend. GPU model variants can need larger downloads and more memory; CPU fallback may download a separate model variant. Media and transcript text stay local, although first use downloads model files. Review automatic captions before sharing.
Automatic captions still require browser-decodable English audio, with a limit of 120 minutes and 512 MB per source file. GPU support and speed depend on your browser, drivers, model, and device.
VideoSplat: faster exports with a fallback
Auto export tries hardware-preferred WebCodecs encoding, then software encoding. Supported WebM and MP4 files export directly from timeline frames with mixed audio, captions, and visual edits. This can finish faster than playing the entire timeline; it is not a guaranteed speed increase.
Choose CPU · software frame encoding or Compatible if needed. Unsupported codecs or failed fast exports fall back to the compatible exporter with a status message. OGM uses the compatible path. Cancel stops the job without starting another export. MediaSplat’s trimming, joining, and subtitle burn-in continue to use its existing FFmpeg processing.
Available now on the live site
These updates are deployed on drawsplat.org and committed to the current source. The refreshed v3.1.28 downloadable ZIPs include these updates and the September 24 VideoSplat recording fixes. The suite package version and individual app versions are separate.
Browser checks covered continuous strokes, touch cancellation, undo, saved-PDF ink placement, media fallback behavior, and export output. Phone touch checks used browser emulation; physical phones, tablets, and NVIDIA performance were not benchmarked.
