PDF Editor Pro: one live workspace for every PDF task
Most PDF work doesn't fit neatly into a single operation — you annotate a contract, sign it, add a watermark, then password-protect the result before sending it. Doing that across four separate single-purpose tools means re-uploading the same file four times. PDF Editor Pro is one live workspace that does all of it in one place: open a file once, work through as many steps as you need, and export at the end — with a live preview updating on every single change.
It runs entirely in your browser. There is no account, no per-file cap and no watermark forced onto your export, and — unlike almost every competing PDF editor — your document is never uploaded to a server at any point in the process.
Annotate, sign and organize — live, on the actual page
The Edit mode covers the markup you'd expect from a desktop PDF app: text, highlights, underline and strikethrough, shapes, freehand drawing, sticky notes, image stamps and a whiteout tool for quick cover-ups. A dedicated Sign mode lets you draw, type or reuse a saved signature and drop it straight onto the page, with an optional date stamp next to it.
The Pages mode turns the document into a grid of thumbnails you can reorder, rotate, delete or extract from — pull just the pages you need into a brand-new file without leaving the workspace. Every change — an annotation, a rotated page, a moved signature — reflects on the live canvas, the thumbnail strip and the export preview instantly, so you always see exactly what you're about to download.
Merge, split and convert without re-uploading anything
Need to combine a cover letter with a CV, or pull a signed page out of a longer contract? The Merge and Split modes live in the same workspace as everything else — add more files, reorder them, or split by page range, all against the document you already have open. Export handles the output side: PDF, PNG, JPG or plain text, with an option to flatten markups and form fields into the final file.
If you already know you only need one of these operations, the dedicated single-purpose pages — Merge PDF, Split PDF, Image to PDF, PDF to Image, Add page numbers and PDF to Markdown — are still there and just as free; each links back to the full workspace the moment you need more than one thing done.
Protect, compress, watermark and genuinely redact
The Secure mode is where PDF Editor Pro goes further than most free editors. Password protection uses real AES-256 encryption with separate print/copy/edit permission controls — not a cosmetic lock. Compress offers three honest tiers (lossless, strong, extreme) with a live before/after size estimate, so you see the size-versus-quality trade-off before you export. Watermarking supports text or your own logo image, with full control over opacity, angle and tiling.
Redaction deserves special mention: it is a real guarantee, not a black box drawn on top of the page. When you mark a region for redaction, the export rasterizes that entire page at high resolution with the redaction box burned into the pixels *before* the file is assembled — the underlying text and image data is structurally gone from the output, verified automatically after every export. A separate whiteout tool exists for quick cosmetic cover-ups where that stronger guarantee isn't needed.
Fill forms and make scanned PDFs searchable with OCR
PDF Editor Pro detects real AcroForm fields — text boxes, checkboxes, radio buttons, dropdowns — and lets you fill them directly on the page or from a dedicated field list, with an option to flatten the filled values permanently into the export. For scanned documents that have no embedded text at all, the built-in OCR (English, Arabic, or both) recognizes the page and adds an invisible, searchable text layer, so the result can be searched and copied from like any normal PDF — and exporting it to plain text pulls the recognized text automatically.
Five quick-access pages for a single job
If you already know exactly what you need done — and nothing else — five dedicated pages open the same workspace pre-aimed at that one job, so you're never more than one click from exporting: Compress PDF for shrinking file size, Protect PDF for adding a password, Unlock PDF for removing one you already know, Watermark PDF for stamping text or a logo, and Extract PDF pages for picking specific pages into a new file.
Each of those pages is the exact same private, on-device engine as the full workspace — just scoped to one job by default, with an "Open full workspace" link the moment you realize you need to do something else to the same file too. See the full PDF tools guide for a walkthrough of the whole toolkit.
Frequently asked questions
Is my PDF uploaded anywhere?
No. Every mode — annotate, sign, merge, split, organize, protect, compress, watermark, redact, fill forms and OCR — runs entirely in your browser. Your document is read, edited and exported on your own device and never sent to a server.
Is it really free?
Yes — no account, no per-file or per-page cap, and no watermark forced onto your exports. PDF Editor Pro and all 5 quick-access pages are completely free to use.
What's the difference between redact and whiteout?
Whiteout draws a white rectangle over content — quick, but the underlying text or image technically still exists in the file structure underneath it. Redaction is a stronger guarantee: the whole page is rasterized with the redacted area burned into the pixels before export, and the tool automatically verifies the covered text can no longer be extracted from the output.
Can I use the compress-pdf or protect-pdf pages instead of the full workspace?
Yes — Compress PDF, Protect PDF, Unlock PDF, Watermark PDF and Extract PDF pages each open the same workspace pre-aimed at that one job, which is faster if that's the only thing you need done to the file.
Does it work on my phone?
Yes — the whole workspace, including OCR and compression, runs in any modern mobile browser, with the same on-device privacy as the desktop version.
Whether you need one quick operation or a document that goes through annotation, signing, protection and compression before it's ready to send, PDF Editor Pro does it in one place, entirely on your device — free, with no account and nothing ever uploaded.
