PDF Studio workspace
Load several PDFs and images, arrange their pages, then export one file with every option applied.
Files are processed on your device and never uploaded.
Export
Use the workspace in 4 steps
- Add PDFs or images with the file picker or by dropping them on the page.
- Drag thumbnails to reorder pages; rotate, duplicate or remove them.
- Choose export options: page size, page numbers, watermark, metadata, compression and a password.
- Export and save the new PDF. Your originals are never changed.
Questions and limits
No. PDF Studio has no upload server. Your files are opened, changed and saved inside this browser tab by JavaScript and WebAssembly running on your device. You can check it yourself: open your browser's developer tools, watch the Network tab while you use the tool, and you will see that no request carries your file.
Not yet. Every page and its content are kept, but the source files' bookmarks (the outline) and interactive form fields are dropped when pages are combined into a new file. Rebuilding bookmarks is planned.
No. Changing a PDF writes a new file, and that invalidates any digital signature it had. Sign the document again after editing it.
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: desktop browsers handle files of several hundred megabytes. On phones and tablets we warn you above about 200 MB or 1,000 pages.
Yes, after the first visit. The app and the processing engines are stored in your browser's cache, so the core tools keep working without a connection once they have loaded once.
Yes. There is no account, no watermark added to your output, no ads and no paid tier.
