PNG vs JPG: what changes
PNG keeps every pixel exactly, which suits screenshots, diagrams and text but makes photographs heavy. JPG discards detail the eye barely notices, so a photographic PNG often shrinks to a fraction of its size.
The trade-off is that JPG softens hard edges and can leave faint ringing around text and thin lines, and the loss cannot be undone. Transparent pixels are flattened onto white. Keep the original PNG if you might edit the picture again.
How to convert PNG to JPG on any device
Screenshots
Screenshots on Windows and macOS are saved as PNG by default. Drag them from your Desktop or screenshots folder onto the page to get JPGs that are easy to attach.
Straight from the clipboard
Copy an image, click the page and press Ctrl+V (Cmd+V on a Mac). Pasted pictures enter the converter exactly like dropped files.
Getting under an upload limit
Job portals, ID checks and marketplaces often cap the size of an upload. Turning a photographic PNG into a JPG is usually the quickest way to fit.
Troubleshooting PNG to JPG
Text and lines look slightly fuzzy
JPG is built for photos, and even at 92% quality it blurs sharp edges a little. For text-heavy screenshots, keep the PNG.
The JPG is bigger than the PNG
This happens with flat graphics and interface screenshots. PNG compresses large areas of one color extremely well, and a high-quality JPG may not beat it.
My transparent logo now sits in a white box
JPG has no transparency, so the see-through area is filled with white. Use the PNG to WebP converter to shrink the file and keep the transparency.
Color profile and metadata
PNG files sometimes carry a color profile or text chunks, and screenshots may include the software that made them. None of that is copied to the JPG, which is rendered in sRGB, so very saturated wide-gamut colors can look a little duller.
