Question 1

What presets are included?

Accepted Answer

WeChat-style 200KB, general job/forms 500KB, web hero with 1920px width and 800KB, and YouTube thumbnail 1280×720 with 200KB. Each preset is a practical target with short notes—not an exhaustive list of every site.

Question 2

What does the checker validate?

Accepted Answer

For the preset you pick, it compares the file size in KB and, when defined, maximum width and height in pixels against your image. You get pass/fail and quick links to compress or resize.

Question 3

How do I fix a failing image?

Accepted Answer

Use the pills under the result to open compress or resize flows, or follow the CTAs on the rule (e.g. 200KB, 500KB).

Question 4

Are these limits official or guaranteed?

Accepted Answer

No. They are common heuristics and notes for real-world uploads. Requirements change by product and region—always confirm on the destination uploader.
