How to convert DNG to PNG
- Drop the DNG files.
- Nothing to choose — PNG is lossless.
- Press Convert and download the PNGs.
What happens to your file
The raw is developed on Fylane’s servers with LibRaw — demosaiced, white-balanced as shot, rendered to sRGB — and written as an 8-bit PNG with no compression loss, then deleted on schedule.
A PNG of a 12-megapixel photo is 20–40 MB: right for an editor, wrong for a message. Use DNG to JPG for anything you send.
Questions
Why is the PNG so large?
PNG compresses without losing anything, and a photograph has little to compress: every pixel is different from its neighbour. That is the price of lossless.
Does the PNG keep the raw’s extra dynamic range?
No — it is 8-bit sRGB, like any screen. The DNG is the negative; keep it for that.
Do it once, not on every form
A form that wants a square JPEG under 240 KB says so on the page. The Fylane extension reads that, fits your photo to it, and puts it in the field — without you working out what 240 KB looks like.
And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.
Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.
