Why convert PNG to JPG?
The usual trigger is size or a picky upload form. Screenshots and design exports default to PNG, and a full-screen PNG can weigh ten times what a JPG of the same scene does, which matters for email attachment limits, slow uploads and bloated slide decks. Plenty of forms and legacy systems also whitelist only .jpg. Converting flattens the image into the one format every device on earth can read. If your PNG is a logo, diagram or text-heavy screenshot, consider staying lossless instead: JPG softens hard edges.
What is PNG?
PNG (Portable Network Graphics) is a lossless image format from 1996. It compresses with DEFLATE, keeps every pixel exactly as authored, and supports a full 8-bit alpha channel for transparency. That makes it the default choice for screenshots, UI mockups, logos and anything with sharp edges or text. The tradeoff is size: photographs stored as PNG are often several times larger than a visually identical lossy file.
What is JPG?
JPG (or JPEG, for the Joint Photographic Experts Group that standardized it in 1992) is the most widely supported image format ever shipped. It uses lossy DCT compression tuned for photographs, which buys small files at the cost of discarding fine detail, and it has no transparency support. Practically everything that can open an image can open a JPG.
Quality and what to expect
This is a lossless-to-lossy move, so it is one way: the JPG discards information the PNG was preserving, and converting back will not recover it. Hard edges and flat color areas may show faint ringing artifacts. PNG transparency does not survive either; JPG has no alpha channel, so transparent regions lose their transparency in the output. If the backdrop matters, flatten the image onto a background color in an editor first. Metadata is not copied over, which also means no hidden EXIF tags ride along.
PNG to JPG FAQ
Will my transparent background turn white?
Not necessarily, and you should not count on it. JPG simply has no transparency, and this converter discards the alpha channel rather than compositing it, so fully transparent pixels keep whatever color values they carried underneath. Flatten the PNG onto white (or any color) in an image editor first if the background matters.
How much smaller will the JPG be?
For photographic content, typically 60-90% smaller than the source PNG. For flat-color graphics the gap shrinks, and a small icon can even come out larger as a JPG because lossless PNG is genuinely the better fit there.
Does my PNG get uploaded anywhere during conversion?
No. The encoder is WebAssembly running in a web worker on your device. You can open your browser developer tools and watch the network tab while converting: no request carries your image.
Should screenshots be JPG or PNG?
If the screenshot contains text or UI and you care about crispness, keep PNG. If you need to email a dozen of them or a form rejects PNG, JPG is the pragmatic choice and the text will still be perfectly readable at normal sizes.
