A toolbox for one-off tasks: merge a PDF, shrink a photo, clean up messy text, convert a file your computer refuses to open. No account, no watermark, no daily limit, and no paid tier that gates features.
101 of the 169 tools run entirely in your browser — Canvas, WebAssembly and Web Crypto. The file is processed on your own machine and never uploaded. This is verifiable rather than a promise: open the Network tab while a tool runs and there is no upload request. The AI background remover works this way too — it downloads an ONNX segmentation model and runs inference locally.
The other 68 tools are server-backed, because a browser genuinely cannot read EPS, XPS, PSD, HEIC, AVIF, OpenDocument, Publisher, Visio, WordPerfect, Works or Apple iWork files. Those run on LibreOffice, Ghostscript, ImageMagick, qpdf and Tesseract. The file travels over HTTPS, is converted in an isolated workspace, and is deleted the moment the result is returned. Every server-backed tool says so on its own page.
| Tool | Why it is not the usual one |
|---|---|
| OCR to searchable PDF | Tesseract adds a real selectable text layer, not an image |
| Background remover | ONNX model running on-device via WebAssembly, or WebGPU where available |
| HEIC to JPG | libheif decoding, so iPhone photos actually open |
| PDF toolkit | merge, split, rotate, compress, watermark, page numbers, protect, unlock, repair, reorder |
