Frequently asked questions
Is this PNG to MIFF converter really free?+
Yes. There's no file limit, no watermark, and no account required. Because the conversion runs in your browser instead of on a server, there's no processing queue to pay for.
Is my file uploaded anywhere?+
No. Orbfile decodes and re-encodes the image locally using ImageMagick compiled to WebAssembly, running entirely inside your browser tab. The bytes never leave your device.
Will converting to MIFF lose quality?+
There's a quality slider so you can balance file size against visual quality. At high quality settings the difference is usually invisible.
Can I convert more than one file at once?+
Yes — drop as many files as you like and download them individually or as a single ZIP.
Is there a maximum file size?+
There's no fixed upload limit — Orbfile isn't uploading anything. The practical ceiling is your device's own memory, which comfortably handles even large, high-resolution photos.
How do I convert PNG to MIFF?+
Drop your PNG file into the box above — it's automatically converted to MIFF and a download link appears in seconds. No settings are required, though you can adjust quality if the tool offers a slider.
About PNG and MIFF
What is PNG?
PNG is a lossless image format built for sharp edges, flat colors, and transparency — think logos, screenshots, and UI graphics rather than photos.
Full PNG format guide →What is MIFF?
MIFF (Magick Image File Format) is ImageMagick's own native format, built to losslessly preserve every image attribute ImageMagick knows about.
Full MIFF format guide →The short version: MIFF gives you preserves every image attribute and metadata field losslessly, which helps once you run into PNG's biggest limitation: much larger files than JPG for photographic content. It's a natural move when your image is headed toward a lossless intermediate step in an ImageMagick-based batch or scripted workflow.
How it works
- 1
Drop your file in
Drag your image onto the box above, or click it to browse — there's no account to create and no upload to wait on.
- 2
Pick your settings
The output format is already set for this page — just adjust any extra options shown, if there are any.
- 3
Download the result
Your browser processes everything locally and hands you a download link the moment it's done — nothing was ever sent to a server.
Is it private?
Everything happens locally, inside this browser tab. Your image is read from disk, processed with WebAssembly running on your own device, and handed back to you as a download — it's never transmitted anywhere, so there's nothing to intercept and nothing stored on a server.
Common use cases
- A lossless intermediate step in an ImageMagick-based batch or scripted workflow
- Preparing images for a website or online store
- Attaching a photo to an email with a size limit
- Getting a screenshot ready to share or document

About PNG files+
PNG is a lossless image format built for sharp edges, flat colors, and transparency — think logos, screenshots, and UI graphics rather than photos.
PNG (Portable Network Graphics) was created in the mid-1990s as a free, patent-unencumbered replacement for GIF, and it inherited GIF's lossless approach while adding full 24-bit color and an alpha transparency channel. Because nothing is thrown away during compression, a PNG can be re-saved indefinitely without ever degrading — a real advantage for screenshots, diagrams, and anything with text or hard edges, where JPEG's compression tends to introduce visible smudging. The cost is file size: for photographic content, a PNG is typically several times larger than an equivalent JPEG, which is why most photo libraries still default to JPEG and reserve PNG for graphics.
How to open a PNG file
Opens readily in Any web browser, Your operating system's default photo viewer. For real editing, use Adobe Photoshop, GIMP, Affinity Photo.
Good for
- lossless — no generation loss on re-saving
- full alpha transparency
- crisp text and hard edges
Watch out for
- much larger files than JPG for photographic content
About MIFF files+
MIFF (Magick Image File Format) is ImageMagick's own native format, built to losslessly preserve every image attribute ImageMagick knows about.
John Cristy created MIFF alongside ImageMagick itself in 1999 as a platform-independent way to save an image mid-workflow without losing anything to a lossy or metadata-limited format. A MIFF file is a plain-text header of keyword=value pairs — color profile, comments, compression, class — followed by the raw pixel data, so unlike JPG or even PNG, it can round-trip every piece of state ImageMagick tracks internally. That makes it a solid choice as a lossless intermediate file in an ImageMagick-based pipeline, though outside that ecosystem almost nothing else can open it.
How to open a MIFF file
Opens readily in For real editing, use ImageMagick, GraphicsMagick.
MIFF is ImageMagick's internal working format — general-purpose photo viewers and editors won't recognize it.
Good for
- preserves every image attribute and metadata field losslessly
- simple, well-documented text-plus-binary structure
Watch out for
- essentially unsupported outside ImageMagick/GraphicsMagick
