Image Resizer
Forms with a size limit, avatars, thumbnails and e-mail attachments all need a smaller image. This resizer works on the canvas inside your browser, so the photo is never uploaded anywhere.
How to use it
- Choose an image; its current size appears.
- Type a new width — the height follows automatically while proportions are locked.
- Pick a format, apply, and download the result.
Examples
- A 4000 px camera photo down to 1200 px wide for a blog post.
- 512 × 512 for a square avatar, with proportions unlocked to force the shape.
- Exporting to WebP usually gives the smallest file of the three formats.
Questions people ask
Does resizing lose quality?
Making an image smaller discards detail permanently, which is normally what you want. Making it larger cannot invent detail and simply looks soft, so always resize down from the largest original you have.
Which format should I export?
JPEG for photographs, PNG when you need transparency or crisp flat graphics, and WebP when you want the smallest file and modern browser support is enough. Note that exporting to JPEG replaces transparency with white.
