Everything a PDF editor should do

✏️

Annotate

Pen, highlighter, text boxes, sticky notes, rectangles, ellipses and arrows. Full undo/redo.

📝

Fill & Sign

Click to place typed text on any field. Draw, type or upload a signature and position it freely.

✍️

Sign

A dedicated signing flow: draw, type or upload a signature that stays draggable and resizable after you place it, and remembers your last signature for next time.

⬛

Redact

Permanently black out names, account numbers or any sensitive content before sharing.

💧

Watermark

Stamp a text or logo watermark — tiled, centered or in a corner — as real vector text, not a flattened image.

🔢

Page numbers

Number pages in any position or format, with a custom start number and an optional skip-first-page.

🗂️

Organize

Rotate pages, delete unwanted pages and drag to reorder before downloading.

These 7 tools above share the PDF you're working on — load it once in any tab and the others offer to continue with it, no re-upload needed. Need to merge, split, compress, password-protect or convert a PDF instead? Those are each their own dedicated, focused tool: Merge PDF · Split PDF · Compress PDF · Protect PDF · PDF to JPG · PDF to Text · Images to PDF · OCR

PDF editor FAQ

Is my PDF uploaded anywhere?

No. Everything runs in your browser using pdf-lib and PDF.js. Your documents never leave your device — ideal for confidential contracts, medical records and financial statements.

How do I annotate a PDF?

Open the Annotate tab, load your PDF, then choose a tool from the toolbar: pen for freehand drawing, highlighter for colored boxes, text for typed notes, or shapes for rectangles and ellipses. Ctrl+Z undoes any annotation. Click "Download annotated PDF" to save.

Is redaction permanent?

Yes. Redaction boxes are burned as solid black rectangles into the PDF when you download. The underlying content is not recoverable from the downloaded file. Always keep your original document separately.

How do I fill in a PDF form?

Open the Fill & Sign tab, load your PDF, select the Text tool and click anywhere on the page to place a text field. Type your content and click elsewhere to finish. Use the Signature tool to draw or type your signature.

Is there a page or file size limit?

No server-side limits. Very large PDFs (50+ pages, lots of images) may be slow depending on your device. For very large files, use the Organize tab to remove pages you don't need before annotating.

Do I have to switch pages to use these tools?

No. Annotate, Fill & Sign, Sign, Redact, Watermark, Page numbers and Organize are all tabs on this one page. Load a PDF in any tab and the others offer a one-click "Continue with this PDF" so you never have to re-upload the same file to use a different tool.

What's the difference between "Fill & Sign" and "Sign"?

Fill & Sign is the full form-filling toolkit (text fields, checkboxes, dates, plus a signature). Sign is a focused signing-only flow where the signature stays draggable and resizable after you place it, and remembers your last signature for next time — use whichever fits what you're doing.

Where are Merge, Split, Compress, Protect and the file converters?

Those are each their own dedicated free tool, so they stay fast and focused: Merge PDF, Split PDF, Compress PDF, Protect PDF, PDF to JPG, PDF to Text, Images to PDF and OCR.
