Turn a heavy PNG into a compact JPG you can email, upload or attach anywhere — with a quality slider so you decide the size/detail trade-off.

PNG stores every pixel losslessly, which is why a full-page screenshot can easily run 4–8 MB. JPG throws away detail the eye barely registers and routinely lands the same image under 400 KB, which is why mail servers, job portals and older upload forms still prefer it. The catch is transparency: JPG has no alpha channel, so any transparent area has to become a solid colour. This converter flattens transparency onto white before encoding, so you never get the black boxes that cheap converters produce. Keep quality at 90 for photographs and screenshots you want to look untouched, drop to 70–80 when file size matters more than pixel-level fidelity, and preview the result before you download it.
JPG is a lossy format, so some detail is discarded. At quality 90 the difference is invisible in normal viewing; below about 70 you may notice softening around sharp text and edges.
JPG cannot store transparency, so transparent pixels are filled with white before encoding. If you need to keep transparency, convert to WebP or stay with PNG.
Typically 60–90% smaller for screenshots and photographs. Flat graphics with few colours sometimes compress better as PNG, so compare both if size is critical.
No. The conversion runs entirely in your browser using the Canvas API — the file is never transmitted anywhere.
There's no imposed limit. Very large images are bounded only by your device's available memory.
It's free, private and works right in your browser — no signup, no watermark.
