Frequently asked questions
Is this MIFF to PNG 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 PNG lose quality?+
No — PNG is lossless, so you won't lose any additional quality beyond what the source file already had.
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 MIFF to PNG?+
Drop your MIFF file into the box above — it's automatically converted to PNG and a download link appears in seconds. No settings are required, though you can adjust quality if the tool offers a slider.
About MIFF and PNG
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 →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 →People usually reach for this conversion because PNG offers lossless — no generation loss on re-saving, sidestepping a real MIFF weak spot: essentially unsupported outside ImageMagick/GraphicsMagick. It's especially useful for logos and icons.
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
- Logos and icons
- Screenshots
- Preparing images for a website or online store
- Attaching a photo to an email with a size limit

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
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
