PDF Tools
Everything here reads, edits, and rebuilds PDF files directly in your browser — the documents never upload to a server. That matters more for PDFs than almost any other file type, because PDFs are where contracts, statements, medical records, and IDs live. Compress a file for email, merge a signing packet, convert to Word for edits, or sign and send — without the document ever leaving your device.
Which PDF Tool Do I Need?
Rebuilds each page at a lower quality setting you control. A scanned 20 MB agreement typically lands under 5 MB.
Extracts the document into an editable .docx. Best on digitally-created PDFs; scans need OCR first.
Reorder pages by dragging, combine multiple files, or pull out a page range as its own PDF.
Turns one or many images into a single paginated PDF — receipts, whiteboards, ID scans.
Add text boxes, freehand drawing, and highlights directly onto pages, then export a flattened copy.
Draw or type a signature, place it precisely, and export. The signed document is never transmitted anywhere.
Why These Tools Run in Your Browser
Upload-based PDF sites work by receiving your document on their servers, processing it there, and holding it — usually with a stated deletion window — while you download the result. For low-stakes files that tradeoff may be fine. For the documents PDFs usually contain, it means your contract or bank statement spends time on infrastructure you don't control, subject to policies you can't verify.
These tools take the other path: the PDF engine (built on the same open-source foundations used by Firefox's PDF viewer) is downloaded to your browser once, and your file is parsed, transformed, and rebuilt in your machine's memory. You can watch the network tab while it happens — we published exactly that test in our Privacy Audit. The practical bonus: no upload and download round-trip, so large files often finish faster than a server service on the same connection.
Don’t take the privacy claim on faith — we published a network-level verification in the Privacy Audit and measured processing speed in the Speed Benchmark.
Frequently Asked Questions
Is there a file size limit?
The limit is your device's memory rather than an arbitrary plan tier. Files in the hundreds of megabytes work on a typical laptop. Very large scans on older phones can run out of memory — if that happens, split the document first and compress the parts.
Are these PDF tools really free? What's the catch?
Free, no account, no watermarks, no daily quota. The site may show ads, and because processing happens on your device, our costs don't scale with your file sizes — which is why we don't need to meter usage the way server-based services do.
Can I use them offline?
Largely, yes. After a page has loaded once, the processing runs locally, and the site is installable as an app. An internet connection is only needed to load a tool the first time.
Will compressing a PDF make the text blurry?
Compression re-encodes page images at a quality level you choose, and the preview shows the tradeoff before you commit. Text in digitally-created PDFs stays sharp at moderate settings; heavily-compressed scans degrade first in photos and fine print.
Is a signature from Sign PDF legally valid?
A drawn or typed signature image is generally treated like a signed fax — widely accepted for everyday agreements, but it is not a cryptographic digital signature or a notarized e-signature service with an audit trail. For regulated signing workflows, use a dedicated e-signature provider.
