Examples
Avatar photo
Shrink a large photo to 400×400 px (with aspect ratio on, fit the shorter side first, then crop elsewhere if you need a square).
Blog image
A width of 1200 px is usually enough for articles — a smaller file loads faster.
Family print preview
Shrink for a quick preview; for high-quality printing, do not go below the resolution your print shop requires.
When to use it
• When a form rejects dimensions that are too large.
• When you want faster page loads.
• When you need a quick resize without Photoshop.
Dimensions vs. file size
Reducing pixel dimensions usually cuts file size sharply because there are fewer pixels. That is often more effective than JPEG compression alone on huge phone photos (e.g. 4000 px wide down to 1200 px for the web).
Frequently asked questions
Which formats are supported?
JPG, PNG, and WebP — depending on your browser.
What does keeping aspect ratio do?
Changing one side automatically adjusts the other so the image is not stretched.
Can I only make images smaller?
You can enter larger dimensions, but quality will not magically improve.
What is the output format?
PNG for PNG sources; otherwise usually JPEG.
Is EXIF/GPS removed?
Saving through a canvas usually drops EXIF metadata — often desirable before publishing.
