Image Resizer
Resize images directly in your browser — no server upload required. Lock the aspect ratio to avoid distortion, choose output format (JPEG, PNG, or WebP), and set quality. Useful for resizing photos before upload, creating web-optimized images, and generating thumbnails.

JPEG, PNG, WebP, GIF — max 20 MB
Tips & tricks
- All processing happens locally in your browser — your images are never uploaded to any server.
- WebP format typically produces smaller files than JPEG at the same quality level.
- Enlarging an image beyond its original dimensions will reduce quality (pixelation).
- For web use, aim for images under 200 KB for fast page load times.
- JPEG is best for photographs; PNG is best for graphics with transparency; WebP is best for both.
