This Image Resizer tool helps you optimize images for any purpose:
This image resizer supports JPEG/JPG, PNG, GIF, WebP, and AVIF formats. You can upload any of these formats and even convert between them during the resizing process.
When "Lock aspect ratio" is enabled, changing either width or height automatically adjusts the other dimension to preserve the original proportions of your image, preventing distortion.
JPG: Best for photos, smaller files, no transparency.
PNG: Supports transparency, ideal for logos and graphics.
WebP: Modern format with better compression than JPG/PNG.
AVIF: Latest format with the best compression and quality.
The maximum file size for uploads is 10MB. If your image exceeds this limit, you may need to compress it first before uploading.
The quality slider controls compression: higher values (75-100) give better quality but larger files, while lower values (10-50) create smaller files with some quality loss. The default "High (90)" setting provides excellent results.
