Convert PNG to JPG Instantly

When PNG to JPG is the right call

PNG is a lossless format, which is exactly what you want for anything with hard edges: screenshots, diagrams, UI mockups, logos, pixel art. It is exactly what you do not want for a photograph, because lossless compression of continuous-tone data produces enormous files. A 12-megapixel photo saved as PNG is routinely 15-25 MB; the same photo as a quality-90 JPG is 2-4 MB and looks the same on any screen.

So the useful rule is about content, not format. If the image is a photograph, converting to JPG is nearly free. If it is a screenshot of text, converting to JPG costs you legibility for a size saving you may not need.

What you give up

The email and upload-limit case

Most of the traffic to this page comes from a size limit. Gmail attaches up to 25 MB per message, many contact forms cap at 5 MB, and job application portals often cap at 2 MB per file. A handful of PNG screenshots will blow past all of those. Converting to JPG at quality 85 and, if needed, resizing the long edge to 1600-2000 pixels will get almost any set of images under a 5 MB limit without them looking degraded on screen.

Privacy

Nothing is uploaded. The file is decoded and re-encoded by your own browser using the Canvas API, so the image never leaves your device and there is no queue, no size cap and no account.
