Edit & Sign PDF — Annotate, Sign, Watermark & Redact
Change what's inside your PDF, free and in your browser: edit text, add a signature, stamp a watermark, black out private details, and spot-check two versions side by side.
Most PDF tools only rearrange pages. This hub is about the harder job: changing what a PDF actually says, shows, and protects. Whether you're filling a job application, signing a rent agreement, watermarking a design proof, hiding your Aadhaar number before uploading a document, or checking whether a vendor quietly changed a contract clause, the five tools here cover the "content" side of PDF work — and every one of them runs free, with no sign-up and no forced watermark.
Start with what you're trying to do. If you need to correct a typo, fill in a blank, add a date, or drop your details into a form that wasn't built as a fillable form, use Edit PDF. It's the everyday workhorse: type over a scanned admission form, add your roll number to a hall ticket, or fix a misspelled name on an offer letter before you print it. Indian government and college portals often hand you flat, non-fillable PDFs, and Edit PDF lets you write on them without printing, filling by pen, and re-scanning.
When a document needs your name at the bottom, reach for Sign PDF. You can draw your signature with a mouse or finger, type it, or upload a scanned image of your handwritten sign, then place it exactly where it belongs — on a rental agreement, an employment offer, a GST-related declaration, a bank form, or a school consent letter. This matters for the WFH generation: instead of printing an offer letter, signing, scanning, and emailing it back, you sign in the browser and send a clean PDF in one go. It's a genuine time-saver for anyone dealing with HR paperwork or freelance contracts.
Use Watermark PDF when you want to stamp text or an image across your document — "DRAFT", "CONFIDENTIAL", "COPY", your company name, or a diagonal "Not for circulation." Small businesses sending GST invoices, designers sharing proofs, coaching institutes distributing notes, and anyone circulating a sample document all benefit from a visible mark that says "this is mine" or "this isn't final." You control the text, opacity, and angle, so the watermark protects the file without making it unreadable.
Redact PDF is the one people most often skip and most need. Before you upload a bank statement to a loan portal, share a PAN card scan, or send a document with your address, phone number, or account number, you should permanently black out the parts you don't want exposed. Real redaction removes the underlying content, not just covers it with a rectangle you can drag away later — important when the receiving side could otherwise copy hidden text. Use it on Aadhaar and PAN details, salary slips, bank statements, and any KYC document where over-sharing is a privacy and fraud risk.
Finally, Compare PDF answers a question that saves money and disputes: "did anything change?" Put two versions side by side — an old and revised contract, a first and final draft of an agreement, two copies of a policy document, or a resume before and after edits — and see what's different. Landlords, freelancers, and anyone signing terms they didn't write should compare the version they agreed to against the version they're asked to sign.
A natural workflow ties these together. Say you've received a job offer as a PDF: open it in Edit PDF to fill in your joining date, use Sign PDF to add your signature, then run Compare PDF if HR sends a revised copy to confirm only the agreed fields changed. Or take a bank statement you need for a visa application: Redact PDF to hide your account number, Watermark PDF to stamp "For [Embassy] use only," and you're done. For a design or document proof going to a client, Watermark PDF marks it as a draft and Sign PDF adds your approval once it's final.
Two honest reminders. First, these are editing and marking tools, not legal-signature services — Sign PDF places a visible signature, which is fine for most everyday forms, offers, and internal paperwork, but a court-grade digital signature (DSC) for filings like income tax or MCA is a separate certificate-based system. Second, on redaction: always download and reopen the redacted file to confirm the sensitive text is truly gone before you share it. Used together, these tools let you handle almost any "change the PDF" task — annotate, sign, watermark, redact, and compare — without installing software, creating an account, or paying for a subscription. Pick the tool that matches your job below, and everything stays in your browser.
Frequently Asked Questions
Can I edit a PDF for free without a watermark or sign-up?
Yes. Edit PDF and every other tool in this hub run free in your browser with no account and no forced watermark on your output. You only get a watermark if you deliberately add one using Watermark PDF.
Is signing or editing a PDF online safe for documents like Aadhaar or bank statements?
For sensitive files, edit and then use Redact PDF to permanently remove private details before sharing. Prefer tools that process in your browser, download the finished file, and reopen it to confirm the redaction actually removed the text rather than just covering it.
Does a signature added with Sign PDF count as a legally valid e-signature?
Sign PDF adds a visible signature that works for most everyday needs — offer letters, rent agreements, consent forms, freelance contracts, and internal paperwork. For court-grade filings such as income tax or MCA submissions, India requires a certificate-based Digital Signature Certificate (DSC), which is a separate system.
How do I black out sensitive information so it can't be recovered?
Use Redact PDF, which removes the underlying content instead of just drawing a box over it. After redacting your PAN, account number, or address, download the file, reopen it, and try to select or copy the hidden area to confirm the text is truly gone before sharing.
What's the difference between Edit PDF and Watermark PDF?
Edit PDF is for changing or adding actual content — filling a form, fixing a typo, inserting your details. Watermark PDF overlays a repeated mark like DRAFT or a company name across the whole document to show ownership or status, without altering the original text.
