This free converter writes a PNG from your JPG in the browser. It is worth being clear about what that does and does not achieve: the compression damage already baked into the JPG stays there, because no converter can recover detail that was discarded when the JPG was saved. What you gain is a lossless container, so every subsequent save, crop and edit stops adding fresh damage on top — which is exactly why PNG is the right working format and JPG is a delivery format. Nothing is uploaded.

How to use it
- Check the output is set to PNG — This page opens with the output format already set to PNG, 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.
- Add your JPG 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
JPG loses a little more every time it is re-saved. Edit a JPG five times and you are looking at five generations of compression artefacts stacked on each other, which shows up first as mush around text and blotches in flat colour.
What it does
A lossless working copy
Every edit and re-save from here adds no further compression damage, which is the entire reason to convert before editing rather than after.
Alpha channel available
The PNG can carry transparency once you cut a background out. The conversion itself does not create transparency — nothing can guess which pixels you meant to remove.
Full resolution kept
Pixel dimensions are unchanged, so the file remains usable at the same print sizes.
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, artwork in any common format feeds the bulk mockup renderer directly.
Questions
Will converting to PNG improve my image quality?
No, and be suspicious of any tool that says otherwise. The detail a JPG discarded is gone. Converting stops further loss; it does not undo the loss already there.
Does this make the background transparent?
No. It gives you a format that can hold transparency. Removing a background is an editing step, and no automatic conversion can know which pixels you consider background.
Why is the PNG so much bigger?
PNG is lossless, so it stores everything including the JPG's compression artefacts. A photograph will often be three to five times larger as a PNG.
When should I keep the JPG instead?
When it is a photograph being delivered rather than edited — a listing image, an email attachment, anything going straight to a viewer. JPG is the right format for that job.
