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.

Files never uploaded Runs in your browser No signup No watermark

Converting PNG screenshots to PDF on iPhone

iPhone screenshots save as PNG files by default. PNG is lossless and preserves sharp text and UI elements perfectly — ideal for screenshots. However, many submission portals, university systems and official forms accept only PDF. Converting your screenshots to PDF in Safari on iPhone requires no app download and no desktop computer.

Method 1: PDFWix in Safari (Recommended)

Open Safari on your iPhone.
Go to PDFWix Image to PDF.
Tap the upload area. Select your PNG screenshots from the Photos library or Files app. You can select multiple screenshots at once.
Drag to arrange them in the correct order.
Choose page size: Fit to image (preserves exact screenshot dimensions) or A4 portrait (scales screenshots to A4).
Tap Convert to PDF. Download the file — it saves to your Files app or Downloads folder.

Method 2: iOS built-in Print to PDF

For single-page conversions: open the PNG in the Photos app. Tap Share → Print. In the print preview, perform a pinch-zoom outward on the preview thumbnail — this opens the full-screen PDF preview. Tap the Share icon in the top right and choose Save to Files. This converts the single PNG to a PDF using iOS's built-in print engine. For multiple screenshots, this method is tedious — use Method 1 for batches.

Batch converting screenshots on iPhone

For batches of 5 or more screenshots, PDFWix Image to PDF is significantly faster than any iOS built-in method. Select all screenshots at once during upload, drag to correct order, and convert in one tap. The output is a single multi-page PDF — ideal for submitting multi-page forms, preserving chat logs, or packaging evidence screenshots.

Frequently asked questions

Do iPhone screenshots save as PNG or JPG?

iPhone screenshots always save as PNG files. PNG preserves sharp edges and text without compression artifacts, which makes it ideal for screenshots. If you need JPEG screenshots (for platforms that do not accept PNG), convert using PDFWix Image to PDF then export as JPG.

Can I convert iOS long screenshots (scrolling screenshots) to PDF on iPhone?

Yes. Long screenshots on iPhone are saved as standard PNG files — PDFWix Image to PDF converts them the same way as regular screenshots. If the long screenshot is very tall, choose Fit to image page size so the entire screenshot fits on one PDF page without cropping.

What is the best page size setting when converting iPhone screenshots to PDF?

Use Fit to image for most screenshot conversions. This preserves the exact pixel dimensions of each screenshot as the PDF page size. Use A4 portrait only if the PDF needs to match standard A4 paper dimensions (for printing or official submission systems that require A4 format).
