Resize image dimensions by exact pixels (width × height) or percentage scaling while locking aspect ratio. Built with high-quality Lanczos resampling to prevent blurriness and keep fine lines sharp.
How to Use
Select images from your device or drag an entire folder into the dropzone above.
Enter exact pixel dimensions (Width x Height), lock aspect ratio, or choose percentage scaling.
Width
1920 px
Height
1080 px
Download perfectly scaled images formatted for websites, social media, or official documents.
Before
4000 × 3000 px
After
1920 × 1080 px
Drag and drop multiple photos and apply standard dimensions (like 1080×1080 for Instagram, 1200×630 for Facebook) across all of them simultaneously.
Downscaling maintains crisp clarity. Upscaling very small images can lead to pixelation, so it is best to resize from high-resolution originals.
Yes, enable 'Lock Aspect Ratio'. Changing width will automatically calculate and adjust height to prevent stretching.
Use exact pixel dimensions when fitting specific social media or portal requirements. Use percentage scaling when you want to downscale high-res camera batches uniformly while retaining their original aspect ratio.
Most people confuse DPI with resolution. This guide explains the real relationship between DPI and pixels, why changing DPI metadata doesn't add detail, and when 300 DPI genuinely matters.
