Document & AI
Turn documents into clean text for Claude, ChatGPT, Notion, or a repo — with token counting and chunk splitting built in.
Image
Convert between image formats, resize, and batch-process — metadata (EXIF/GPS) is removed automatically on conversion.
Audio & video
Convert audio and short video clips, or shrink a video to a smaller MP4 — all encoded on your own device.
Reorganise, shrink, and repurpose PDFs — merging and splitting keep text selectable and quality intact.
CAD & 3D
Recover editable geometry from drawings and move 3D models between formats — confidential work stays on your machine.
Compress
Get a file under an email or upload limit without uploading it to a stranger first.
한국어 (Korean)
Korean-language versions of our most-used tools.
New to the site? The guides explain when to use each format and tool, and the how-we-prove-it page shows how to confirm nothing is uploaded.
