Is PDFWix really free?

Yes. Every tool on PDFWix is free to use with no daily task limits and no watermarks added to your files. We may charge for high-volume API usage in the future, but the web tools stay free.

Do I need to create an account?

No. Every tool works without signing in. An optional free account just keeps a history of your conversions (filename and tool only — never your files) and unlocks the developer API.

Do you store my files?

Most tools (merge, split, rotate, watermark, edit, JPG↔PDF, etc.) run entirely in your browser — your file never reaches our server. The two tools that need server processing (Protect PDF, Unlock PDF) process your file in memory and never write it to disk.

What's the maximum file size?

Browser-side tools handle PDFs as large as your device's RAM allows — roughly 100 MB on a typical laptop, less on phones. Server-side tools (Protect, Unlock) accept files up to about 25 MB per request.

Do you add watermarks to my PDFs?

No. PDFWix never adds a watermark, footer, or branding to anything you create. The output is exactly what you asked for, nothing else.

Does PDFWix work on iPhone, Android, and Chromebook?

Yes. PDFWix is a web app — it runs in any modern browser on any device. There's nothing to install. You can also add it to your home screen on iOS or Android for a one-tap launcher.

How is PDFWix different from iLovePDF or Smallpdf?

Three differences: most PDFWix tools run inside your browser (your file never leaves the device), there are no daily task caps on the free tier, and we never put a watermark on your output. As of June 2026, PDFWix has 24 live tools across merge, split, compress, sign, redact, and convert with no daily task limit and no file upload for 22 of them.

Is PDFWix safe for confidential documents?

For browser-side tools, yes — your file is processed locally and never transmitted anywhere. For the two server-side tools (Protect, Unlock), files travel over HTTPS and are processed in memory only. We never read, scan, or train AI on your documents.

Can I use PDFWix for commercial work?

Yes. There's no license restriction on what you produce with PDFWix. Use it for client work, internal documents, contracts, anything. The developer API is available if you need to embed PDF processing into your own product.

What happens if a tool fails or I find a bug?

Email support@pdfwix.com or use the "Report an issue" link in the footer. We read every message and ship fixes quickly.

Which PDF tools run entirely in my browser?

Twenty-two of the 24 PDFWix tools run entirely in your browser using WebAssembly — your file never leaves your device. The two exceptions are Protect PDF and Unlock PDF, which require server processing but handle your file in memory only and never write it to disk.

Is there a file size limit?

Browser-based tools handle files up to the available RAM on your device — typically 500MB or more on modern computers. Server-side tools (Protect, Unlock) currently support files up to 100MB.

Does PDFWix work on iPhone and Android?

Yes. All 24 PDFWix tools are fully optimised for mobile browsers. No app install required — open pdfwix.com in Safari on iPhone or Chrome on Android and every tool works exactly the same as on desktop.

Sign PDF Free — No Account

Live · in browser

Google Drive has no built-in PDF signing feature. The fastest free workaround: download the PDF from Drive, open PDFWix Sign PDF in your browser, sign it, download the signed PDF, then re-upload to Drive. The entire process takes under 2 minutes. No account required.

Does Google Drive have a PDF signing feature?

Google Drive does not have a built-in PDF signing tool as of 2026. You can view PDFs in Drive, annotate them with comments, and open them in Google Docs (which loses the original formatting), but you cannot add a legally valid electronic signature directly within Google Drive's interface. Google Workspace includes DocuSign integration as an add-on, but this requires a paid DocuSign subscription.

The fastest free workaround: Download → Sign → Re-upload

Open Google Drive and find your PDF.
Right-click the PDF → Download. It saves to your device.
Open PDFWix Sign PDF in a new browser tab.
Upload the downloaded PDF. It stays in your browser — not uploaded to any server.
Add your signature by drawing, typing or uploading a signature image.
Position and download the signed PDF.
Go back to Google Drive, click New → File Upload, and upload the signed PDF.
Optionally delete the original unsigned version from Drive.

Signing Drive PDFs on mobile

On iPhone and Android, the process is the same. Open Drive on your phone, download the PDF to your device storage, open a browser (Chrome or Safari), go to PDFWix Sign PDF, upload the PDF from your device, sign with your finger, download, and re-upload to Drive through the Drive app. The whole process works in the browser — no additional app needed.

Google Workspace alternative: DocuSign add-on

If you sign PDFs from Drive frequently, Google Workspace Marketplace offers the DocuSign add-on which allows signing Drive files directly without downloading. This requires a DocuSign account (free tier: 5 documents per month). For occasional signing, the PDFWix free browser method is faster and has no monthly limit. See also our guide to signing PDFs without creating an account.

Frequently asked questions

Can I sign a PDF in Google Drive without downloading it?

Not with built-in Drive features. Google Drive has no native PDF signature tool. To sign a Drive PDF without downloading, use the DocuSign add-on from Google Workspace Marketplace (free tier: 5 documents per month). For unlimited free signing, download → sign with PDFWix → re-upload.

Will re-uploading a signed PDF to Drive create a duplicate?

Yes, uploading a new file to Drive creates a new file. Drive does not automatically replace the original. If you want to replace the original, right-click the original PDF in Drive, select Manage versions, and upload the signed version as a new version. Drive keeps both versions but shows only the latest by default.

Is it safe to sign PDFs from Google Drive using PDFWix?

Yes. PDFWix Sign PDF processes files entirely in your browser. The PDF from your Drive is never sent to PDFWix servers — it is downloaded to your device, processed locally in your browser, and downloaded again as the signed file. No PDFWix account is created and no data is stored.
