Resized image
This tool works locally in your browser. It does not verify whether a photo meets an authority's face, background, signature or other submission rules.
How to Resize a Passport Photo Online
Follow these steps to resize your image:
- Select Passport / Exam Photo or Custom Image.
- Upload the image from your device.
- Enter the required width and height in pixels.
- Choose an aspect ratio or keep the original ratio where appropriate.
- Select the target file size in KB.
- Choose JPG, PNG or WebP as the output format.
- Click Resize & Compress Image.
- Review the output dimensions and file size, then download the image.
Always compare the output with the instructions provided by the relevant application portal before uploading it.
How to Resize a Photo Under 20 KB
Some online forms specify a maximum file size in KB. To prepare an image under 20 KB, select a target of 20 KB or less and use JPG or WebP if those formats are accepted.
If the output is still too large, try reducing the pixel dimensions. Lowering image quality can also reduce file size, but excessive compression may make the image blurry.
A file-size target is not a guarantee. The final size depends on image dimensions, image content, format and compression. Check the downloaded file before submitting it.
SSC Photo Resize and Signature Size for Online Forms
Candidates applying for Staff Selection Commission examinations should read the latest notification for their specific examination.
Requirements can differ between recruitment cycles. Some recent SSC application procedures instruct candidates to capture their photograph live through the application module instead of uploading a pre-existing photo file. Signature requirements may specify a particular JPEG/JPG file size and physical dimensions.
For example, the SSC CHSL 2025 notice specifies a scanned signature in JPEG format between 10 KB and 20 KB, with dimensions of approximately 6.0 cm wide by 2.0 cm high. Requirements for a later examination may differ.
This tool can resize a supplied image, but it cannot replace a live-photo capture process when the application portal requires one. It also does not verify whether an image meets the official background, face-position, signature or other acceptance rules.
How to Resize a Signature for an Online Form
To prepare a signature image:
- Sign clearly on plain paper using the method accepted by the application authority.
- Scan or photograph the signature with sufficient lighting.
- Crop the image carefully so that the signature remains readable.
- Upload the image to the resizer.
- Enter the dimensions and file-size limits specified in the official instructions.
- Select JPEG/JPG if required by the form.
- Download the result and check that the signature is clear and legible.
Do not make the signature so small that it becomes blurred or difficult to read.
Understanding Image Dimensions and Aspect Ratio
Image dimensions are measured in pixels. For example, an image measuring 200 × 230 pixels has a width of 200 pixels and a height of 230 pixels.
The aspect ratio describes the relationship between width and height. Keeping the correct ratio helps prevent unwanted stretching. However, if an application requires exact dimensions, you may need to crop or fit the image into the required frame.
Do not stretch a face or signature disproportionately just to match the requested dimensions.
JPG, PNG or WebP: Which Format Should You Choose?
- JPG/JPEG: Commonly accepted for photographs and many application forms. Compression can reduce file size.
- PNG: Useful when lossless image quality or transparency is required, but files may be larger.
- WebP: Can offer efficient compression, but it should only be used if the application portal accepts it.
Always follow the permitted format stated in the official instructions.
Frequently Asked Questions
Can I resize a photo to 20 KB online?
Yes. Set the target to 20 KB and process the image. If the result remains larger than the target, reduce its dimensions or adjust the permitted output settings.
Can I resize a signature for an SSC application?
Yes. You can resize a signature to specified dimensions and a target KB size. Check the latest SSC notification for the exact requirements of your examination.
Does this tool upload my image to a server?
Image processing takes place in your browser. The plugin does not send the selected image to its own server for resizing.
Why is my resized image still larger than the required KB?
The image may contain too much detail for the selected dimensions and quality settings. Try reducing the dimensions or using an accepted compressed format. PNG files cannot always meet a strict size target.
Does resizing guarantee that my application image will be accepted?
No. Acceptance depends on the official requirements, including dimensions, file size, format, image clarity and any live-photo or signature rules.
