Resize Images Online Free

Resize Images Online - Fast, Free, and Private

Need to resize images for social media, your website, or email? Our free image resizer tool lets you quickly resize photos to any dimension—right in your browser. Whether you need to resize JPG, PNG, or WebP files, you can adjust dimensions by pixels, percentage, or use our convenient social media presets.

Three Ways to Resize Images

1. Resize by Pixels (Exact Dimensions)

Set exact width and height in pixels for precise control. Enable "maintain aspect ratio" to prevent image distortion—the tool automatically calculates the correct dimensions to keep your photo proportional. Perfect when you need specific dimensions for website layouts or design requirements.

2. Resize by Percentage (Proportional Scaling)

Scale your image proportionally by percentage. Enter 50% to make it half the size, or 200% to double it. This method is ideal for shrinking images uniformly or creating larger versions while maintaining exact proportions.

3. Social Media Presets (One-Click Sizing)

Choose from pre-configured sizes optimized for social platforms:

• Instagram Square: 1080×1080px - Perfect for feed posts
• Instagram Portrait: 1080×1350px - Ideal for vertical photos
• Facebook Post: 1200×630px - Optimized link sharing
• Twitter Post: 1200×675px - Fits Twitter feed perfectly
• Full HD: 1920×1080px - Standard HD resolution
• Email Friendly: 800×600px - Small file size for attachments

Why Use This Image Resizer?

100% Private and Secure

Unlike other online image resizers that upload your photos to remote servers, our tool processes everything locally in your browser using HTML5 Canvas. Your images never leave your device, ensuring complete privacy—especially important when resizing sensitive documents, personal photos, or confidential business materials.

No File Size Limits

Many free photo resizer tools limit uploads to 5MB or 10MB. Our tool has no restrictions—resize images of any size without limitations. Process high-resolution photos, large graphics, or multiple images without upgrading to premium plans.

Maintain Image Quality

Control output quality with our adjustable slider. Balance file size against image clarity. Set high quality (85-100%) for professional use, or reduce to 50-70% for faster website loading while maintaining acceptable appearance.

Works Offline

Once loaded, our image resizer functions without internet connection. Process photos during flights, in remote locations, or anywhere without WiFi—perfect for travelers and mobile professionals.

Tips for Best Results

Maintaining Aspect Ratio

Always keep "maintain aspect ratio" checked unless you specifically need a different shape. This prevents image distortion (stretching or squashing). When you change width, height automatically adjusts to keep proportions correct.

Quality Settings

• High (85-100%): Use for professional photos, printing, or archival
• Medium (70-84%): Good balance for most web use and social media
• Low (50-69%): Maximum compression for email or slow connections

Upscaling Considerations

While you can increase image dimensions (e.g., making a 500px image 2000px), this won't add detail that wasn't there originally. For best quality, always start with high-resolution source images and downsize rather than upscale.

Privacy and Security

Traditional online image tools require uploading files to remote servers, creating privacy concerns and security risks. Our client-side processing means:

• No Upload: Images stay on your device
• No Storage: We can't access or store your files

Browser Compatibility

Frequently Asked Questions

Does resizing reduce image quality?

Downscaling (making images smaller) generally maintains good quality. Our tool uses high-quality algorithms to preserve detail. You control final quality with the slider—higher percentages retain more detail but create larger files.

Can I resize multiple images at once?

Currently, process one image at a time. For batch resizing, upload each image individually—the tool is fast enough for quick sequential processing.

What's the maximum image size?

No hard limit! Process images up to your browser's memory capacity (typically several hundred megabytes). Very large images may take a few seconds to process.

Do you keep my photos?

Absolutely not. Images are processed entirely in your browser using JavaScript. We never receive, store, or access your files. When you close the tab, everything is cleared from memory.

Can I use this for commercial projects?

Yes! Free for personal and commercial use without restrictions. No attribution required.
