ImResizer: Compress, Resize & Convert

Ultimate Guide: Compress Image to 20KB, 50KB & Resize Online

Welcome to ImResizer, the most advanced yet simple online utility designed specifically for students and job aspirants. Whether you are applying for SSC (CGL, CHSL, MTS), UPSC (Civil Services), IBPS (Banking), RRB (Railways), or GATE exams, one common hurdle is resizing your photograph and signature to strict specifications.

Forms often reject images because they are "too large" (above 50KB) or have "incorrect dimensions" (not 6cm x 2cm). Our tool solves this instantly by allowing you to compress images to 20KB, 50KB, 100KB and resize them to exact centimeters, millimeters, or pixels without losing quality.

1. How to Compress JPEG to 20KB, 50KB, or 100KB?

Reducing image file size (KB) is crucial for faster uploads and meeting server limits. Here is a step-by-step guide to using our Image Compressor to 50KB feature:

1. Upload Your Photo: Click the upload box or drag and drop your image (JPG, PNG, WEBP).
2. Set Target KB: In the "Target Size (KB)" field, enter the maximum limit allowed by your form.
   • For SSC Signature: Enter 10 to 20.
   • For SSC Photo: Enter 20 to 50.
   • For UPSC Photo: Enter 20 to 300.
   • For IBPS Signature: Enter 10 to 20.
3. Set Dimensions (Optional): If the form asks for specific dimensions (e.g., 3.5cm x 4.5cm), enter them in Width and Height.
4. Click Compress: Our algorithm will iteratively adjust quality to ensure the file is under your limit but keeps maximum clarity.

2. Resize Image to 6cm x 2cm (Signature Resizer)

One of the most unique features of ImResizer is the ability to resize directly in Centimeters (cm) and Millimeters (mm). Most basic editors only allow pixels, leaving you to guess the conversion.

Why 6cm x 2cm?

Many offline forms and specific government portals (like state police exams, driving license forms) require a signature box of exactly 6cm width and 2cm height. If your image aspect ratio is different, it will look stretched. Use our Crop Tool first to select the signature tightly, then resize to 6x2 cm.

3. Advanced Features: DPI and Aspect Ratio

While basic resizing changes width and height, professional forms often mention DPI (Dots Per Inch). A standard screen image is 72 DPI, but printable forms require 200 to 300 DPI.

What does ImResizer do?

When you select "cm" or "mm" in our tool, we automatically calculate the required pixels based on the DPI setting (default 300). This ensures that when your application is printed by authorities, your photo remains sharp and clear, avoiding rejection.

Aspect Ratio Lock

By default, the "Maintain Aspect Ratio" box is checked. This prevents your photo from looking squashed or stretched. If you need to force an image into 6x2cm despite it being square, uncheck this box, but be warned: the result might look distorted.

4. Troubleshooting: Why Was My Photo Rejected?

Even after resizing, photos get rejected. Here are common reasons and fixes:

• Blurred Face: You compressed the image too much (e.g., trying to fit a 5MB HD photo into 10KB). Fix: Crop the face closer before compressing.
• Background Issue: SSC requires a clear, light background without glasses/caps. Fix: Use a proper source photo.
• Wrong Extension: Form asked for JPG but you uploaded PNG. Fix: Our tool automatically exports as JPG universally compatible format.
• Dimensions Mismatch: You uploaded 3.5x4.5cm where 4x5cm was needed. Fix: Check the official notification and use our Width/Height inputs.

5. Frequently Asked Questions (FAQ)

Q: Is it safe to upload my personal photos here?

A: Yes, absolutely. ImResizer is a client-side application. This means the code runs inside your browser (Chrome/Edge/Safari). Your images are never sent to our server. We cannot see, save, or copy your data. It is as safe as editing it on your own computer.

Q: How to compress image to 20kb for SSC signature?

A: Upload signature -> Select 'cm' unit -> Enter Width 4.0, Height 2.0 -> Enter '20' in Target KB box -> Download.

Q: Can I resize pixels to cm?

A: Yes, simply upload a pixel-based image, switch the unit dropdown to 'cm', and enter your desired cm values. The tool handles the math.

Q: Does this tool support bulk resizing?

A: Currently, we focus on precision editing for single images (photo/signature) to ensure maximum quality for official forms.
