Format
iPhone HEIC photos: convert them to JPG first.
Which quality to choose
- 75 to 85 for websites, portfolios and social media: the file is usually a fraction of the original and the difference is hard to see on a screen.
- 90 or more for images that will be printed or edited again.
- Below 70, look closely at skies and skin: flat areas show blocks and banding first.
JPG, WebP or PNG
WebP gives the smallest file at the same visible quality and every current browser shows it, which makes it the best choice for your own website. JPG is the safe choice for email, clients and print labs, because every program opens it. PNG keeps every pixel, so it barely shrinks a photo: use it for logos and screenshots, and the longest-side setting if you need a smaller PNG.
What else changes
The compressed file does not keep the original’s metadata: camera settings, capture date and GPS location are removed. That is usually what you want before posting a photo online. Keep your originals as the master copies.
