How to convert JPG to PNG
- Drop the JPG.
- Nothing to choose.
- Press Convert and download the PNG.
What happens to your file
The JPG is decoded once and stored losslessly, so no further quality is lost — but the detail JPG already discarded does not come back. Converting cannot un-compress.
The PNG will be larger, often much larger. That is the cost of a format that can be edited and re-saved without accumulating damage.
Questions
Does converting to PNG improve the quality?
No. It stops further loss; it cannot restore what JPG removed.
Why would a form require PNG?
Usually for transparency (logos) or to avoid JPG artefacts on documents. If it is a photo, the requirement is arbitrary and this conversion satisfies it.
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.
