This free converter turns PNG images into JPGs in your browser, with a quality slider so you decide the trade between file size and fidelity. A photographic PNG typically drops to a tenth of its size as a JPG at 92% quality with no visible difference — which is usually the difference between an image a marketplace rejects and one it accepts. Transparent areas are composited onto white, because JPG has no alpha channel. Nothing is uploaded.

Lossy and small. No transparency — transparent areas become white.

How to use it
- Check the output is set to JPG — This page opens with the output format already set to JPG, so there is nothing to configure if that is what you came for. If you actually wanted something else, change it here — the same page converts to PNG, JPG, WebP, TIFF and PDF.
- Set the quality — JPG is lossy, so the slider runs from 40% to 100% and the resulting file size is shown after each change. Around 90% is the usual sweet spot — below about 80% you start to see haloing around text and hard edges.
- Add your PNG files — Drag them onto the drop area or click to choose them — one file, or up to thirty at once. They are read in your browser, so nothing is uploaded, there is no queue and no account is needed.
- Let it convert — There is no Convert button — conversion starts as soon as a file is added, and the results panel shows the total size going in and coming out so you can see what the change cost or saved.
- Download the results — Each converted file has its own download link. If you converted several, "Download all as ZIP" saves the whole set in one action.
The problem this solves
PNG is lossless, which is another way of saying enormous. A 300 DPI mockup exports at forty megabytes, Etsy caps listing images well below that, and the file has to come down somehow. Doing it by re-exporting from a design tool means opening the design tool.
What it does
Quality you control
A slider from 40% to 100%, with the output size shown after each change, so you can find the point where the file is small enough and still looks right.
Transparency flattened onto white
JPG has no alpha channel. Transparent areas are composited onto white instead of turning black, which is what happens when a converter drops the channel without compositing.
Full resolution kept
The pixel dimensions do not change — only the compression. A 6000-pixel poster stays 6000 pixels.
Whole folders at once
Drop in up to thirty files and every one is converted. Multiple outputs download together as a ZIP, so a set of listing images is one action rather than thirty.
Nothing is uploaded
The conversion runs in your browser using the same image pipeline the browser uses to show you a photo. Your file never reaches a server, there is no queue, and there is no account to make. It also means a large file is limited by your own machine's memory rather than by an upload cap.
Where it lives in PSDmate
Free and open on this page. Inside PSDmate, listing images are generated at the size and format Etsy wants without a manual export.
Questions
What quality setting should I use?
Start at 90–92%. Below about 80% you begin to see haloing around hard edges and text, and photographs go blotchy in smooth gradients like skies.
Why did my transparent background go white?
JPG cannot store transparency. White is the sane default; if you need the transparency, stay on PNG or use WebP, which is smaller than PNG and keeps alpha.
Can I convert back to PNG later?
You can, but the quality lost in the JPG stage does not come back. Keep the PNG as your master and treat the JPG as a delivery copy.
Does this reduce the image dimensions?
No. Pixel dimensions are unchanged — only the compression differs. That matters for print, where pixels are what determine the size you can output at.
