Frequently asked questions

Is this PNG to AVIF 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 AVIF 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 AVIF?+

Drop your PNG file into the box above — it's automatically converted to AVIF 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 AVIF

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.

What is AVIF?

AVIF is a newer, next-generation image format built on the AV1 video codec, delivering some of the smallest file sizes available today.

Full AVIF format guide →

The short version: AVIF gives you often 50% smaller than PNG or JPG at visually similar quality, 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 performance-focused websites.

How it works

  1. 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. 2

    Pick your settings

    The output format is already set for this page — just adjust any extra options shown, if there are any.

  3. 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

  • Performance-focused websites
  • Archiving large photo libraries in less space
  • Preparing images for a website or online store
  • Attaching a photo to an email with a size limit

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 AVIF files+

AVIF is a newer, next-generation image format built on the AV1 video codec, delivering some of the smallest file sizes available today.

AVIF takes the intra-frame compression from the royalty-free AV1 video codec and repurposes it for still images, and the result is often noticeably smaller than an equivalent WebP or JPEG at the same visual quality. It also supports wide color gamuts, HDR, and transparency, making it one of the more technically complete image formats available. The tradeoff is encoding speed and, until recently, patchier software support — both are improving quickly as browsers and operating systems catch up.

How to open a AVIF file

Opens readily in Chrome, Firefox, Edge, Safari (recent versions). For real editing, use GIMP (recent versions), Affinity Photo.

Some older photo viewers and editors need an add-on or a recent update to open AVIF directly.

Good for

  • often 50% smaller than PNG or JPG at visually similar quality
  • supports transparency and HDR

Watch out for

  • slower to encode
  • not yet supported everywhere older software runs
