FormatPic is a free, browser-based online image converter that lets you convert between 10 image formats instantly. FormatPic processes everything in your browser — your files never leave your device.

FormatPic supports PNG, JPG, WebP, HEIC, GIF, BMP, TIFF, SVG, ICO, and AVIF — that's over 90 conversion combinations, all completely free with no account required, no watermarks, and no ads on your converted images.

Our Mission

We built FormatPic because we were frustrated with the status quo of online image conversion. Every existing tool required uploading personal photos to remote servers, imposed arbitrary limits on free usage, and added unnecessary friction — signups, captchas, email verification — to a task that should take seconds.

Our goal is simple: make image conversion as fast, private, and frictionless as possible. No accounts. No uploads. No limits. You open the page, drop in your images, and get results instantly. That is the entire experience, and we think it is how every tool should work.

Why FormatPic?

Most online image converters — like CloudConvert, Convertio, or Zamzar — upload your files to remote servers for processing. This creates privacy risks, imposes file size limits, and adds upload/download wait times. Many also gate features behind paid subscriptions or limit free users to a handful of conversions per day.

FormatPic takes a fundamentally different approach. By processing images entirely in your browser using WebAssembly and the HTML5 Canvas API, FormatPic eliminates all of these problems:

Privacy-first architecture — Your images never leave your device. This is not a policy promise — it is a technical guarantee. No data is transmitted to any server during conversion. You can verify this by monitoring network traffic in your browser's developer tools, or by disconnecting from the internet and confirming that conversion still works.
No file size limits — Without server uploads, the only limit is your device's memory. Most modern computers and phones handle images up to 50 MB without issues.
Instant processing — No upload or download wait. Conversion happens in milliseconds because your device does the work directly.
Truly free — No conversion quotas, no daily limits, no premium tier. FormatPic costs almost nothing to operate because your device does the processing, so there is no reason to charge.
Works offline — Once loaded, FormatPic works without an internet connection. The JavaScript and WebAssembly code runs entirely locally.

Privacy and Security

Privacy is not a feature we added to FormatPic — it is the foundation the tool is built on. The decision to process everything client-side was the first architectural choice we made, and every other design decision flows from it.

When you convert an image on FormatPic, the file is read into your browser's local memory, processed using JavaScript and WebAssembly, and the result is saved directly to your device. At no point does any image data leave your browser or travel over the network. FormatPic does not operate any image processing servers, does not store any user files, and does not have any infrastructure that could be breached to expose your images.

This matters especially for:

Personal photos — iPhone photos (HEIC files) often contain GPS metadata, faces, and private moments. Converting them should not require sending them to a stranger's server.
Professional work — Client images, photographs under NDA, and proprietary designs can be converted without any confidentiality concerns.
Sensitive documents — Passport photos, legal documents, and medical images stay on your device throughout the entire process.

How FormatPic Works

FormatPic uses the HTML5 Canvas API and specialized WebAssembly modules to convert images entirely in your browser. When you select a file, it is read into local memory using the browser's File API. The image is decoded — either natively by the browser (for formats like JPG, PNG, WebP) or via WebAssembly decoders (for formats like HEIC that browsers do not natively support).

The decoded pixel data is rendered onto a Canvas element, where any resizing or quality adjustments are applied. The Canvas then exports the image in the target format. The result is created as a Blob in memory and offered for download. No server is contacted during any step of this process.
