How to Resize and Compress an Image Without Losing Quality
Resize first or compress first? The wrong order gives you a file that is both larger and softer. The correct sequence, and how to choose a target size.
The short version first, then the parts that usually get skipped.
Resizing and compressing look like two chores and behave like one ordered pipeline. Compress first and you bake in artefacts that resizing then magnifies, so the smaller file can end up looking worse than the larger one did.
What actually works, in order: Set the pixel dimensions from where the image will actually be displayed, then compress to fit the byte budget for that placement. Check the result at 100 percent zoom against the real background colour rather than against white.
The numbers worth knowing: A 4000-pixel photo resized to 1600 pixels and then compressed often lands near 200KB. The same file compressed on its own stays above 1MB and looks worse.
Where people go wrong: Compressing to hit a number without resizing first. You can reach 200KB and still ship something soft and oversized that decodes slower than a well-resized 400KB file.
A note on defaults. Every tool in this space ships with settings chosen for the average case, and if your situation is not average, the default path is what sends you back to redo the work a month later. Decide what you are optimising for in one sentence, then let that sentence filter the steps. Anything that does not connect to it can wait.
I keep the full walkthrough with the order of operations on my own site, here: https://image-compressor-saas.shop/en/blog/resize-and-compress-image
