Resize images by pixel dimensions or percentage. Supports JPG, PNG, WebP. 100% browser-based — files never uploaded to any server.

Frequently Asked Questions

Does the image resizer upload my photos to a server?

No. Image resizing uses the browser's Canvas API — your photos never leave your device. Everything runs locally.

What image formats does the resizer support?

Supports JPG, PNG, WebP, GIF, and most other common image formats. Output is available in JPG and PNG formats.

Will resizing an image reduce its quality?

Reducing dimensions does not noticeably reduce quality. Enlarging an image beyond its original size will reduce sharpness. Use the quality slider to balance file size and visual quality.

Can I resize multiple images at once?

Currently the tool processes one image at a time. For batch processing, open multiple browser tabs or download a desktop image editor.
