What Is Converter.Plus?

Converter.Plus is a free, browser-based file conversion suite that lets you convert, compress, and optimize documents and images without uploading a single file to any server. Whether you're dealing with HEIC photos from your iPhone, AVIF images downloaded from a modern website, WebP files that won't open in your design software, or PDFs that need to land in a different format, Converter.Plus handles the conversion instantly — right inside your browser tab.

Modern file formats have proliferated rapidly over the past decade, and the result is a confusing ecosystem where a file created on one device simply won't open on another. HEIC is Apple's default format for iPhone photos since iOS 11, but Windows doesn't support it without a paid codec. AVIF is a next-generation web format championed by Google and Netflix, delivering stunning compression ratios — but it confuses older software and non-technical users who just want to open an image. WebP, also created by Google, has been the web's preferred format since 2020, yet countless users still encounter "unsupported format" errors when they try to open a saved web image in Photoshop, an email attachment, or a print service.

The traditional fix has been to upload your files to a server-based converter — but that means your personal photos, sensitive documents, and private screenshots travel across the internet to a server you know nothing about. Many of these services have vague privacy policies, retain your files indefinitely, or sell usage data. Converter.Plus was built to solve this problem properly.

Three reasons Converter.Plus is different

No upload needed

Every conversion runs inside your browser using WebAssembly. Your files never leave your device. Not even temporarily. There is no server receiving your images.

Instant results

Without an upload-download round trip, conversion starts the moment you drop a file. Batch jobs that would take minutes on server-based tools are done in seconds.

Completely private

Because nothing leaves your browser, there is no data for us to misuse, sell, or accidentally expose. Your private photos remain private — unconditionally.

Converter.Plus works on every major platform — Windows, macOS, Linux, iOS, and Android — without installing any software, browser extension, or app. It's free to use with no file size limits, no watermarks, and no account required.

Why Converter.Plus?

We built this because we were tired of uploading private photos to sketchy servers just to change a file extension.

100% Private

Your files never leave your device. All processing happens locally in your browser using modern WebAssembly and Canvas APIs. No servers ever see your images.

Lightning Fast

Skip the upload and download wait. Because processing happens locally, conversion starts the instant you drop a file — even for large batch jobs.

Free & Unlimited

No paywalls, no signup, no file size limits, and no watermarks. Convert as many images as you need, completely free, forever.

Works Everywhere

Works on Mac, Windows, iPhone, Android, and any device with a modern browser. No software to install. Convert images from wherever you are.

The free file converter that respects your privacy

Most online converters work by uploading your files to a remote server, running the conversion there, and sending the result back. This means your private photos, screenshots, and documents pass through someone else's computer — often with unclear privacy policies and data retention practices.

Converter.Plus is different. It runs entirely in your browser. When you drop a file, it is decoded and re-encoded using the same JavaScript and WebAssembly engines that power modern web applications — with no network request containing your file data ever leaving your device. This makes it the safest free file converter for sensitive or personal documents and images.

Whether you need to convert HEIC photos from your iPhone to JPG on Windows, save a WebP image from a website as a usable JPEG, turn a PDF into another format, or optimize files for your website without uploading them to a cloud service, Converter.Plus has you covered — for free, with no software to install, on any device.
