Ratios worth knowing
Free cropping suits most jobs, but a fixed ratio saves being cropped again by somebody else’s software. 1:1 is the safe square for avatars and product grids. 4:5 is the tallest an Instagram feed post will show without trimming it. 16:9 matches video thumbnails and most slide decks, 1.91:1 is what link previews use on Facebook and LinkedIn.
Cropping to the ratio the destination wants means you choose what gets cut off rather than an algorithm choosing for you.
What cropping does to quality
Cropping removes pixels; it does not change the ones that remain. What does affect them is saving: a JPG has to be re-encoded, which loses a little each time. One crop is invisible, and a dozen round trips on the same file are not.
PNG and WebP saved losslessly come through untouched. If you are going to crop, rotate and adjust the same photograph, doing it in one sitting costs one re-encode rather than three.
Cropping for a circle
A rectangular crop cannot give you a round avatar — the corners are still there, just filled with something. The circle crop writes real transparency into those corners and saves as PNG, which is what a profile picture needs.
Frequently asked questions
Does cropping reduce the quality?
The pixels you keep are unchanged. Re-saving a JPG re-encodes it, which costs a little quality once — not enough to see on a single crop. PNG and WebP are unaffected.
Can I crop to an exact pixel size?
Crop to the right area and ratio here, then use the resizer to land on exact dimensions. Doing it in that order means you choose the composition and the numbers separately, instead of fighting both at once.
Why does my crop look bigger than I selected?
The preview is scaled to fit the screen, so the selection is in preview pixels while the saved file is in the original’s pixels. A quarter of a 4000px photo is still a 1000px image.
Are my photos uploaded?
No. The crop happens on a canvas in your own browser and the file never leaves your machine — which matters if what you are cropping out is somebody’s address or a document number.
