Resize images online for free. Set custom dimensions for passport photos, government forms, JEE Main, NEET, Aadhaar, and social media. No signup, no watermark.
An image resizer changes the pixel dimensions of a photo — making it wider, taller, smaller, or larger — while keeping the image visually clear. Unlike cropping (which cuts away portions of an image), resizing scales the entire image to fit new dimensions. ToolsWallet's image resizer runs entirely in your browser: your photos are never uploaded to any server. You can resize images to exact pixel dimensions, specific file size limits (like 50 KB for government portals), or standard preset sizes for passports, social media, and competitive exams like JEE Main and NEET.
Different platforms and applications have strict image dimension and file size requirements. Here are the most common reasons people resize images in India:
Our image resizer uses the browser's Canvas API to redraw your image at the new dimensions using bilinear interpolation — an algorithm that produces smooth, high-quality results even when reducing image size significantly. When resizing down (making an image smaller), pixels are averaged and blended to produce a clean result. When resizing up (making an image larger), pixels are interpolated to fill the new space. You can choose to maintain aspect ratio (to prevent stretching) or set custom width and height independently.
Upload your image
Click or drag your JPG, PNG, or WebP photo into the upload area.
Set your target dimensions
Enter the exact width and height in pixels, or select a preset (passport, JEE, NEET, LinkedIn, etc.). Toggle "Lock aspect ratio" to prevent distortion.
Adjust output quality (optional)
For JPG output, use the quality slider to reduce file size while maintaining acceptable visual quality.
Preview and verify
Check the resized image preview and the reported output file size to confirm it meets the portal's requirements.

What are the photo requirements for JEE Main?
NTA requires a passport-sized photograph in JPEG format, between 10 KB and 200 KB, with dimensions of 3.5 cm × 4.5 cm (approximately 100×130 pixels at 72 DPI). The background must be white or off-white.
What are the photo requirements for NEET?
NEET UG requires a recent passport-sized photograph in JPEG format, between 10 KB and 200 KB. The photo must have a white or light-coloured background and show a clear front-facing view.
Will my image quality be maintained after resizing?
Yes. Our tool uses high-quality bicubic interpolation for resizing. For JPG output, you can control the quality level to balance visual clarity and file size.
Can I resize to a specific file size, not just dimensions?
Yes. Use the quality slider to reduce file size while keeping dimensions fixed. The tool shows the file size estimate in real time as you adjust.
Is there a limit on how many images I can resize?
No. You can resize as many images as you need — there are no daily limits, session limits, or usage caps.
