Frequently asked questions
Is this Image Resizer free to use?
Yes, it is completely free with no sign-up or usage limits.
Is my image uploaded to a server?
No. Resizing happens entirely in your browser using the Canvas API — your image is never uploaded anywhere.
What does "lock aspect ratio" do?
When enabled, changing the width automatically recalculates the height (and vice versa) to keep the image's original proportions and avoid stretching or squashing it.
Can I resize and compress at the same time?
Yes, choose a JPEG or WebP output format and adjust the quality slider — the result is both resized and compressed in one step.
What's the largest image I can resize here?
Up to 15MB, with output dimensions capped at 8000 pixels per side to keep the browser tab responsive.
