Free Online Image Resizer & File Compressor
Formatting photos for job applications, academic portals, or official government websites can be tricky. Often, you need an image to meet specific pixel dimensions (like 200x230 pixels for a signature) while simultaneously remaining under a strict file size limit (like 50KB). Our Free Image Resizer solves both of these frustrating problems instantly, directly from your browser.
📐 Pixel-Perfect Control
Resize your physical image width and height explicitly in Pixels (px) or scale down uniformly by Percentage (%).
⚖️ Proportional Scaling
Keep the 'Maintain Aspect Ratio' lock enabled to ensure your photo never looks stretched, squished, or warped.
🎯 Exact KB Size Limits
Use our advanced target slider to force your final image to compress under specific thresholds like 20KB, 50KB, or 100KB.
How to Resize Image Pixels and Compress Size Simultaneously
- Upload your Image: Drag and drop your JPG, PNG, or WEBP file into the tool. The original dimensions and file size are instantly displayed on the left panel.
- Choose your Unit: Toggle between exactly setting physical Pixels (px) or scaling the image down by Percentage (%).
- Adjust Width and Height: Input your target dimensions. Leave the "Maintain Aspect Ratio" box checked if you want the tool to automatically calculate the proportional height or width.
- Set Target KB Limit (Optional): Need the photo under 50KB or 100KB? Use the slider to set a strict target. Our algorithm will optimize JPEG compression behind the scenes to guarantee it fits your limit without destroying quality.
- Download Instantly: Click the download button to securely save the resized image back to your computer or smartphone.
Fast, Secure, and 100% Offline Processing
Your privacy is important to us. Editing sensitive ID photos, signatures, or portrait pictures requires maximum security. That's why MyImageTool.org executes all mathematical resizing and size compression directly inside your web browser. Your images are never uploaded to our servers, protecting you from data retention, quality loss from server compression, or third-party monitoring.
Frequently Asked Questions (FAQ)
How do I resize an image to specific pixels?
Upload your image, ensure the 'Measurement Unit' is set to Pixels (px), and type your required dimensions into the Width and Height boxes. You can uncheck 'Maintain Aspect Ratio' if you need an exact, non-proportional size.
Can I resize an image and compress its KB size at the same time?
Yes! After setting your desired width and height, use the 'Target File Size' slider to restrict the final download size (e.g., under 50KB or 100KB). Our tool handles both the physical resize and the byte-level compression simultaneously.
Why does the height change automatically when I type a width?
By default, the "Maintain Aspect Ratio" setting is checked. This forces the image to scale proportionally so it doesn't look stretched or squished. Simply uncheck the box if you want to set the width and height independently.
