Why JPG
Why convert PNG to JPG?
PNG is perfect while you're editing, but it's heavy. JPG is the format the web, email, and every upload form were built around.
Private by design
Conversion runs inside your browser through the HTML5 Canvas API. Nothing touches a server, which makes the tool safe for IDs, contracts, and personal photos.
Hit exact size limits
Visa portals and job sites demand strict caps. Pick a target and a binary search across quality levels finds the sharpest image that fits. Zero guesswork.
Batch processing built in
Drag in a whole folder of screenshots. Each image converts on its own, then one Download All click collects every result.
Accepted everywhere
Government systems, social profiles, and older software often require JPG specifically and reject PNG outright. Every device made this century opens a JPG.
Free, with nothing held back
No account, no watermark, no daily cap. Your device does the processing, so there's no server bill to pass on to you. And there never will be.

FAQ
Frequently asked questions
How do I convert PNG to JPG online for free?
Drop your PNG files into the converter at the top of this page, choose a quality level or a target file size, then download. The whole process takes under ten seconds and needs no account, email, or installation.
Are my images uploaded to your server?
No. Every conversion happens locally in your browser through the HTML5 Canvas API. You can prove it yourself: switch to Airplane mode after the page loads and the tool keeps working. That makes it safe for ID documents, contracts, and bank statements.
Can I convert PNG to JPG under 100KB?
Yes. Switch to Target Size mode and pick 100KB, the most requested limit on online forms. Presets also cover 50KB, 200KB, 500KB, and any custom value. A binary search across quality levels finds the best image that fits.
Why is JPG so much smaller than PNG?
JPG uses lossy compression that discards visual detail the eye doesn't easily catch, while PNG stores every pixel exactly. The result: a JPG runs 60 to 90 percent smaller than the same image saved as PNG.
Will my image lose quality when converting?
At 90 percent quality the difference is virtually invisible at normal viewing distance. Photographs hold up well even at 80. Screenshots with small text need 90 or above to keep letter edges crisp.
What happens to transparent backgrounds?
JPG can't store transparency, so the converter fills transparent areas with a solid colour. White is the default, with black and any custom colour available. There's also a Transparent option that keeps the alpha channel by saving as WebP instead.
Can I convert multiple PNG images at once?
Yes. Drag in up to 50 files in a single batch. Each one converts independently, and the Download All button grabs every result in one go.
Does this converter work on phones?
Yes. It runs in Safari on iPhone, Chrome on Android, Samsung Internet, and Firefox Mobile with the same guarantee: nothing leaves your handset.
Is there a daily limit on conversions?
No, there is no usage cap. Processing happens on your device rather than our servers, so converting a thousand images costs us nothing and costs you nothing.
What's the largest PNG I can convert?
Each file can be up to 25MB, which covers full-resolution photographs and 4K screen captures comfortably.
Can I convert JPG back to PNG?
You can, but the lost detail never comes back. JPG compression permanently discards data, so a reverse conversion only wraps the same compressed pixels in a heavier container. Hold on to original PNGs when re-editing is likely.
Is a browser converter better than Photoshop for this job?
For straight format changes, yes: a browser tool batch-converts 50 files faster than opening them one by one in Photoshop, and it costs nothing. Photoshop wins when you also need retouching, layers, or colour profile work before export.
