About Image Resizer
An image resizer changes an image's dimensions and file size and can convert its format. Load an image, set new dimensions or quality, and export as PNG, JPEG, or WebP. Everything is processed in your browser, so your images are never uploaded.
Frequently asked questions
- Are my images uploaded to a server?
- No. Resizing, compression, and conversion all happen locally in your browser using the canvas API.
- Which format should I export?
- WebP gives the smallest files at good quality; JPEG suits photos; PNG preserves transparency and sharp edges.
- Will resizing reduce quality?
- Shrinking is generally clean; enlarging past the original size softens detail. Adjust the quality setting to balance size and clarity.
