How JPG works

JPG (or JPEG) uses lossy compression: it throws away fine detail the eye is unlikely to notice, which makes photos dramatically smaller. The cost shows up around sharp edges — text, lines and flat areas of colour can get faint smudges called compression artefacts. JPG has no transparency, and every time a JPG is edited and saved again, a little more detail is lost.

How PNG works

PNG uses lossless compression: every pixel is stored exactly. That makes it ideal for screenshots, diagrams, logos, icons and anything with text, and it supports full transparency. The trade-off is size — a photo saved as PNG is usually several times larger than the same photo as a good-quality JPG.

Where WebP fits

WebP can be lossy like JPG or lossless like PNG, supports transparency, and usually produces smaller files than either. All current major browsers display WebP. Some older desktop apps and upload forms still don’t accept it, which is the main reason people convert WebP back to JPG or PNG.

Quick rules

Photos and camera pictures: JPG (or WebP for websites). Screenshots, text, charts, logos and anything with transparency: PNG (or lossless WebP). Converting a JPG to PNG doesn’t bring back detail the JPG already lost — it only makes the file bigger — so do it when an app requires PNG, not to improve quality.

What changes when you convert

PNG to JPG: transparent areas must be filled with a colour (white unless you choose another), and the result is lossy at the quality you pick. JPG to PNG: the picture looks the same and the file grows. Either way, TextVix turns photos upright using their orientation tag and does not copy metadata such as camera details or location.

Frequently asked questions

Which is better quality, JPG or PNG?

PNG never loses detail, so it is technically higher quality. For photos, a JPG at quality 85–90 is usually indistinguishable to the eye and far smaller.

Why is my PNG so large?

PNG stores every pixel exactly, which suits graphics but not photos. If the image is a photo, convert it to JPG or WebP.

Does converting remove my photo’s location data?

Yes — TextVix doesn’t copy EXIF metadata, including GPS location, into the converted file.
