Step 2: Upload Your Image
Click “Upload Image” in the preview panel, or drag and drop your image file onto the page. Supported formats: JPEG, PNG, and WebP.
Once uploaded, you will see:
- A live preview of your image
- The original dimensions displayed (e.g., 4032 × 3024 px)
Step 3: Choose How to Resize
You have three ways to resize:
Option A — Quick Presets
Click any preset button to instantly set the target dimensions:
- Full HD — 1920 × 1080 (standard monitor, YouTube)
- Instagram Square — 1080 × 1080
- OG Image — 1200 × 630 (Facebook, link previews)
- Twitter Banner — 1500 × 500
- Web Medium — 800 × 600
- Story — 1080 × 1920 (Instagram/Facebook Stories)
Option B — Custom Dimensions
Enter exact pixel values in the Width and Height fields. With the aspect ratio lock enabled (the chain icon), entering a width automatically calculates the correct height to avoid stretching.
Option C — Scale by Percentage
Click a percentage button to scale relative to the original size:
- 25% — quarter size (great for thumbnails)
- 50% — half size
- 75% — slightly smaller
- 150% — 1.5× larger
- 2× — double size
Step 4: Lock or Unlock Aspect Ratio
The aspect ratio lock is on by default. This means if you change the width, the height adjusts automatically to keep the image proportional — preventing distortion.
Turn it off if you need a specific width AND height regardless of proportion (e.g., filling a fixed-size container).
Step 5: Click “Resize Image”
Click the Resize Image button. A live preview updates instantly showing your resized image. The info bar at the bottom shows the new dimensions.
Step 6: Download
Click “Download” to save your resized image. The file is named automatically with the new dimensions in the filename (e.g., photo_1080x1080.jpg).
Tips for Best Results
- Never upscale beyond 150% — enlarging raster images beyond their original size introduces blurriness. Use our AI tools for upscaling.
- Resize before compressing — always resize to the correct dimensions first, then run through the Image Compressor for the smallest file.
- Check DPI for print — for print projects, ensure your image has at least 300 pixels per inch at the printed size.
