Why convert PNG to JPG?
The usual motive is weight. A screenshot or an exported graphic saved as PNG can run to several megabytes, while the same image as JPG often lands under a tenth of that. One thing to remember: transparency cannot survive the trip, so anything see-through comes out on a solid white background.
JPG is what you pick when the file simply has to work: an upload form, a print order, an email attachment, a government portal. Nothing anywhere rejects a JPG.
How to convert PNG to JPG
Drop your PNG files into the box above, or click to pick them from your device.
Adjust the quality slider if you want a smaller file or a sharper result.
Hit convert. The work happens inside your browser, so it takes a second or two per image.
Download each JPG file, or grab them all in one ZIP.
About the formats
PNG — Portable Network Graphics
PNG is lossless: what goes in comes back out pixel for pixel, no matter how many times you re-save it. Add a full alpha channel and you have the natural home for logos, screenshots, diagrams and anything with hard edges or text. The cost is weight — a photograph stored as PNG can be five times heavier than the same photo as JPG.
Strengths
Lossless — no compression artefacts, at any number of re-saves
Full alpha transparency, including soft anti-aliased edges
Universal support, and the default for screenshots and interface assets
Limitations
Far heavier than JPG or WebP for photographic content
No quality dial — you take the file size you are given
Slower to decode at very large dimensions
JPG — Joint Photographic Experts Group
JPEG has been the default photo format for more than thirty years, and that longevity is the entire point: there is no device, browser, printer or application that cannot open one. It discards detail your eye is unlikely to miss, which keeps files small — but it repeats that loss every single time you re-save.
Strengths
Opens on every device, browser, printer and photo lab in existence
Small files, with a quality dial you control
The safest possible thing to attach, upload or hand to someone else
Limitations
Lossy, and the damage accumulates with every re-save
No transparency — see-through areas are flattened onto a solid colour
Noticeably heavier than WebP or AVIF at matched quality

Frequently asked questions
Are my photos uploaded anywhere?
No. The conversion runs entirely in your browser using WebAssembly and the Canvas API. Your images are never sent over the network, never touch a server, and are dropped from memory as soon as you close the tab.
Will I lose quality?
JPG is a lossy format, so some data is discarded. At the default quality of 85% the difference is invisible on screen for most photos. Raise the slider if you plan to print or edit the result.
Is there a limit or a cost?
It is free and there is no account. The only limits are practical: 30 files at a time and 60 MB per file, so that the tab does not run out of memory on a phone.
Can I convert several files at once?
Yes — drop in up to 30 files and they are processed one after another, then downloaded individually or as a single ZIP.
Does it work offline?
Once the page has loaded, yes. The converter itself needs no network connection, so you can drop the connection and keep converting.
Does it work on a phone?
Yes, on iOS and Android. Large batches are slower on a phone because the decoding happens on the device, so stick to smaller groups if things feel sluggish.
