Questions
How do I get a photo under a specific size, like 500 KB?
Name the size instead of a quality. The image is encoded, measured, and encoded again at a different quality until the result sits under the figure you gave. If even the lowest quality is still too big, the next lever is resizing the image down.
Which format gives the smallest file?
For photographs, AVIF and WebP generally produce a smaller file than JPEG at a comparable quality, though JPEG is the one that opens absolutely everywhere. For screenshots, diagrams and anything with flat colour or text, PNG is often both smaller and cleaner than any of them.
Is the compression lossless?
Not for JPEG, WebP or AVIF — discarding detail is how those formats get small. PNG compression is lossless: the pixels come out identical, just stored more efficiently.
Can I compress the same file twice to make it smaller again?
You can, and it mostly costs you. A lossy format discards detail on every pass, so a second round removes quality faster than it removes bytes. Compress from the original rather than from a previous result.
