Convert PNG to JPG — free, without uploading your images
PNG files are huge, and plenty of forms won't take them. Converting to JPG fixes both — here's how to do it in seconds, free, right in your browser, with nothing uploaded.
Free · Unlimited single files · output format: JPG Nothing uploaded · no account · works with Wi-Fi off
Why convert PNG to JPG at all
Size: photographic or complex images in PNG form are often 5–10× larger than the same image as a quality-90 JPG. Screenshots, photos saved as PNG by mistake, exports from design tools — all shrink dramatically.
Compatibility: many upload forms (job applications, government portals, CMS platforms) accept "JPG only". JPG never gets rejected.
Which one is right: PNG is for sharp edges, text, transparency (logos, diagrams, UI screenshots that must stay crisp). JPG is for photos and anything you send, upload or embed where size matters.
Drop in your PNGs (any number up to the daily free allowance).
Set output format to JPG, quality 90% for screenshots or 85% for photos. Leave dimensions unchanged if you only want a format change — set "prevent upscale" and a max size larger than your images.
Download the JPGs.
The conversion runs inside the page — no upload, no account. It also works in reverse if you need it: set output to PNG to go JPG → PNG.
The transparency catch (and how it's handled)
JPG has no transparency layer. A PNG logo on a transparent background becomes either black or white behind the image, depending on the converter. For screenshots and photos this never matters — they have full backgrounds anyway. For logos and graphics, keep them as PNG: that's what PNG is for. This tool composites transparent areas onto white, so nothing turns black unexpectedly.

What a conversion pass looks like (illustration — demo files, never real data):
Like the tool? Own it.
The free page converts unlimited single files. The €9 Batch Image Resizer download is the same tool as a single file: whole folders of PNGs in, one zip of JPGs out, no daily limit, offline forever. One-time payment — no subscription.
JPG is lossy, but at quality 85–90% the difference is invisible in normal use — and the file is a fraction of the size. The quality slider puts you in control.
What happens to transparent areas?
They're composited onto white (JPG has no transparency). For logos that need transparency, keep them as PNG — this tool lets you choose the output format.
Does converting change the image dimensions?
Only if you want it to. Leave the size settings alone for a pure format change, or set a max dimension to resize at the same time.
Are my images uploaded anywhere?
No. The conversion runs entirely inside the page — no server, no account, no network calls. Wi-Fi off? Still works.
Untracked builds single-file tools: no installation, no account, no cloud, no subscription — and no tracking on this page. This guide lives on tools.untracked.tools; every claim on it is about tools you can open and verify yourself.
We use one first-party analytics tool (PostHog, hosted in the EU) to understand which pages and tools are useful. It never sees your files, form contents or search terms, and session recording is off. You can change your mind at any time.
