Why use these pdf tools?
PDFs often contain sensitive data
Contracts, invoices, medical records, tax documents, IDs. Every time you upload one to a "free online PDF service," you are trusting that server with its contents. These tools process everything locally so there is nothing to trust.
No file size surprises
Many hosted services silently cap free uploads at 10 or 20 MB. Here the only limit is your browser's memory, which is typically hundreds of megabytes.
Fast for common cases
Merging and splitting rearrange pages without re-encoding anything, so they finish almost instantly even for large documents. Compression via rasterization is slower but gives dramatic savings for scanned PDFs.
Common use cases
- Combining several scanned pages into a single document to email
- Extracting signature pages from a signed contract to share separately
- Shrinking a large scanned brochure before uploading to a form with a size limit
- Reordering pages in a multi-file report before sending it
Frequently asked questions
Are my PDFs uploaded anywhere?
No. All processing uses in-browser JavaScript libraries (pdf-lib and pdfjs-dist). You can verify this by watching your browser's Network tab.
Can you handle password-protected PDFs?
Not directly. Remove the password in your PDF viewer first (Adobe Acrobat, Preview on macOS, etc.), then use the unprotected file here.
Which compression mode preserves selectable text?
Use Optimize mode on the PDF Compress tool — it keeps the original text layer, links, and bookmarks intact. The Rasterize mode converts pages into images, which gives bigger savings but makes text non-selectable.
Why is my scanned PDF so large?
Scans are typically stored as high-resolution images inside the PDF. Rasterize-mode compression with a lower DPI (96 or 150) can shrink them by 70% or more with minimal visible quality loss.
Can I rotate, add watermarks, or sign PDFs?
Yes — the PDF Organizer rotates, reorders, and deletes pages; the Page Numbers tool stamps numbering. Watermark and signature tools are planned.
