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.

HEIC to JPG Free — Convert in Safari

Live · in browser

Convert HEIC to JPG on iPhone free using PDFWix in Safari — no app download needed. Bonus fix: go to iOS Settings → Camera → Formats → Most Compatible to stop your iPhone saving photos as HEIC at source. Both methods work on all iPhone models with iOS 13 or later.

Why iPhone saves photos as HEIC

Apple introduced HEIC (High Efficiency Image Container) format in iOS 11 in 2017. HEIC stores photos at half the file size of equivalent JPG photos with no visible quality loss. For iPhone storage efficiency, HEIC is excellent — a 12 megapixel iPhone photo is approximately 3MB as HEIC versus 6MB as JPG. However, HEIC is not universally supported. Windows 10 requires a paid Microsoft HEIC codec to view HEIC files. Many web platforms, government portals and form upload systems accept JPG only.

Fix 1: Convert existing HEIC photos to JPG free on iPhone

Open Safari on your iPhone.
Go to PDFWix HEIC to JPG.
Tap the upload area and select your HEIC photo from Photos or Files.
The conversion runs in Safari — your photo never leaves your device.
Download the JPG directly to your iPhone.
The converted JPG is saved to your Photos library or Files app.

Fix 2: Stop iPhone saving as HEIC (prevents the problem at source)

This is the most effective long-term fix. On your iPhone: go to Settings → Camera → Formats → Most Compatible. From this point forward, your iPhone saves all new photos directly as JPG instead of HEIC. This slightly increases file size per photo but means all new photos are immediately compatible with every platform, portal and application without conversion. Existing HEIC photos in your library are not retroactively converted — use Fix 1 for those.

Windows HEIC compatibility

Windows 10 and 11 can view HEIC files if you install the free HEIF Image Extensions from the Microsoft Store, or the paid HEVC Video Extensions. Without these, Windows Explorer shows a blank thumbnail for HEIC files. Converting HEIC to JPG before sending to Windows users avoids this entirely. For combining converted JPG photos into a PDF, see our guide to combining multiple JPGs into one PDF.

Frequently asked questions

Why does iPhone use HEIC instead of JPG?

HEIC (High Efficiency Image Container) stores photos at approximately half the file size of JPG with equivalent visual quality. Apple introduced it in iOS 11 to help users store more photos in limited iPhone storage. The tradeoff is reduced compatibility outside of Apple devices.

Does converting HEIC to JPG reduce photo quality?

Slightly. JPG uses lossy compression, and converting from HEIC to JPG introduces a small amount of additional compression. At high quality settings (85–95%), the quality loss is invisible to the naked eye. PDFWix converts at high quality — the output JPG is visually equivalent to the original HEIC for most practical purposes.

Can I convert multiple HEIC photos to JPG at once on iPhone?

Yes. PDFWix HEIC to JPG supports batch conversion — select multiple HEIC photos in one upload and download all converted JPGs together as a ZIP file. This is useful when you need to convert an entire album or shoot before uploading to a non-HEIC-compatible portal.
