PDF Studio

Open a PDF from your computer or any URL, then edit it on the page: rearrange and merge pages, type on the document, replace images in place, run OCR, and shrink the file. Nothing is uploaded. No browser popups for insert or edit.

Drag & drop PDFs here, or browse

Click anywhere on this card, drop one or many files, or paste a URL. Multi-file drops merge into one document. Processed in your browser — files never leave this device.

Some hosts block in-browser fetch (CORS). If a URL fails, download the file and drop it here instead.
