SSC GD Signature 300 DPI – 6×2 cm & 10

SSC GD signature 300 DPI guide showing 6 by 2 cm, 709 by 236 pixels and 10 to 20 KB JPG checks

An SSC GD signature needs more than a small JPG file. The handwriting should remain complete and readable, the image should be horizontally aligned, the crop should not cut any stroke, and the downloaded result should match the dimensions and file-size instructions displayed in the application form.

The tool above can help you upload the original image, adjust the crop, select custom pixel dimensions, create a JPG within the selected file-size ceiling and review the processed result before downloading.

Important: This is an independent image-processing utility, not an SSC validation service. Verify every requirement through the application form and current official instructions before uploading the result.

What Is the SSC GD Signature Requirement?

Current SSC GD application instructions describe a scanned signature with the following technical profile:

JPEG or JPG format;
File size between 10 KB and 20 KB;
Approximate physical dimensions of 6.0 cm wide and 2.0 cm high;
A resolution of 300 DPI;
Horizontal alignment; and
Clear handwriting that is neither blurred nor miniature.

The word about is important. Physical centimetres have to be represented by whole pixels in a digital image, so a small rounding difference can occur.

Always inspect the requirements displayed in the application you are completing. A specification used for SSC GD should not automatically be treated as the permanent requirement for every other SSC examination.

What Does 300 DPI Mean?

DPI means dots per inch. In scanned or printed-image workflows, it describes how many image samples are assigned to one physical inch.

A digital image also has pixel dimensions. Pixels describe how many picture elements exist across the width and height. DPI metadata describes how those pixels relate to a physical measurement.

These properties are related, but they are not identical:

Pixels describe the digital width and height.
DPI describes the intended physical resolution.
Centimetres describe physical width and height.
KB describes the amount of stored file data.
JPEG quality affects compression and visible detail.

A file can have the requested pixel dimensions but contain missing or incorrect DPI metadata. It can also contain 300-DPI metadata while having unsuitable pixels, file size or crop. Every relevant property should therefore be checked separately.

How Many Pixels Are 6 × 2 cm at 300 DPI?

One inch equals 2.54 centimetres. To convert centimetres into pixels at a specified DPI, use:

Pixels = centimetres ÷ 2.54 × DPI

For a width of 6 cm at 300 DPI:

6 ÷ 2.54 × 300 = approximately 708.66 pixels

For a height of 2 cm at 300 DPI:

2 ÷ 2.54 × 300 = approximately 236.22 pixels

Because an image cannot contain a fraction of a pixel, a practical nearest-pixel output is:

709 × 236 pixels

You may also see 708 × 236 pixels in some tools because that value preserves an exact 3:1 ratio. Both are close to the stated approximate physical measurement. The application form remains the final authority if it displays exact pixel values.

Does 709 × 236 Pixels Automatically Mean 300 DPI?

No. Pixel dimensions alone do not prove that a JPEG contains 300-DPI resolution metadata.

A tool may create a 709 × 236 pixel image without writing an explicit physical-resolution value. Some image viewers may then show no DPI information or apply their own default interpretation.

A complete DPI converter should perform all of the following:

Create the required pixel dimensions;
Write the intended horizontal and vertical resolution metadata;
Set the correct resolution unit;
Save a genuine JPEG file;
Read the downloaded file again;
Verify its dimensions, DPI metadata and file size; and
Report when reliable DPI metadata is unavailable.

The tool should never display “300 DPI verified” merely because the width and height have been set to 709 × 236 pixels.

How to Use the Tool Above

1. Upload the clearest original image

Select the original photograph or scan rather than a screenshot or previously compressed copy. Each new processing attempt should begin from the original file.

The complete signature should be visible, including:

The first and last pen strokes;
Dots and upper loops;
Lower curves;
Underlines; and
Long finishing strokes.

2. Check the application instructions

Confirm that the form currently requests approximately 6 × 2 cm, 300 DPI and a 10–20 KB JPG. Do not select these settings only because they appear in an older guide or another examination page.

3. Select the custom pixel box

When the application requirement matches this profile, use a working output box of approximately 709 pixels wide and 236 pixels high.

The target box should not force the handwriting to stretch. The signature should retain its natural shape while fitting inside the available area.

4. Adjust the crop safely

Begin with the complete original frame. Move the crop boundaries inward gradually only when excessive surrounding space makes the signature appear too small.

Keep a small safety margin around every stroke. A crop is unsafe when:

A letter touches the crop edge;
A dot or loop disappears;
An underline is cut;
The first or last stroke is incomplete; or
The signature appears cramped against the image boundary.

5. Keep the signature horizontal

The handwriting should be presented horizontally. If the original photograph is sideways, rotate the image before final processing.

Rotation should be controlled by the user. A tool should not automatically rotate the signature unless it can do so confidently and allows the original orientation to be restored.

6. Process the JPG

Create the result from the original uploaded pixels. The output should use genuine JPEG encoding and should remain inside the file-size range stated by the application form.

A working maximum below 20 KB can leave a small technical margin, but the downloaded file must not fall below the stated minimum.

7. Review the actual preview

Inspect the processed result at its actual output size. Confirm that:

The complete handwriting remains visible;
The signature is not stretched;
The signature does not appear miniature;
The image is horizontally aligned;
The output dimensions match the selected values;
The downloaded size is between the stated limits;
The file format is genuinely JPG or JPEG; and
No unexpected visual change has been introduced.

8. Open the downloaded file

Open the downloaded JPG from the file manager or gallery before uploading it. Check that it displays normally and that the actual file information matches the result shown by the tool.

Do not edit or save the downloaded JPG repeatedly. Repeated JPEG compression can reduce thin-stroke clarity and change the file size.

DPI, Pixel Dimensions and File Size Are Separate

Property	What It Controls	Possible Problem
DPI	The intended physical image resolution	Metadata may be missing or incorrect
Pixel dimensions	The digital width and height	The output box may not match the form
Physical dimensions	The intended size in centimetres or inches	Conversion can be rounded to whole pixels
File size	The amount of stored data	The JPG may be below or above the allowed KB range
Crop	The retained portion of the original image	Strokes may be cut or excessive space may remain
JPEG quality	The amount of compression	Excessive compression may blur fine strokes

Meeting one requirement does not automatically satisfy the others. A 300-DPI label does not guarantee the correct KB range, and a 15-KB JPG does not guarantee a safe crop.

Why Can a 300-DPI Signature Still Be Rejected?

The signature is blurred

DPI metadata cannot restore detail that is missing from an unclear original photograph. Begin with a focused image and avoid repeated compression.

The handwriting appears miniature

A large amount of unused surrounding space can make the signature look extremely small when the complete image is fitted into the application preview.

Reduce excess space carefully without cutting the handwriting. The signature rejection guide covers miniature and blurred results in more detail.

The signature is vertically aligned

A portrait or sideways image may not match a horizontally aligned signature requirement. Review the processed preview before downloading.

The file is outside 10–20 KB

Pixel dimensions and DPI do not determine an exact JPG file size. The result also depends on image detail, background texture and JPEG compression.

The crop cuts a stroke

A technically correct file can still be unsuitable when any part of the handwriting is missing.

The file is not a genuine JPEG

Renaming a PNG or WebP extension to JPG does not convert its underlying format. Use genuine JPEG encoding.

Read the PNG-to-JPG signature guide for more information.

The form currently requests different values

Application requirements can change. A setting that is correct for one examination or form should not be assumed for every SSC application.

Changing DPI Metadata Alone Is Not a Quality Improvement

Changing a number in the image metadata does not create new handwriting detail. A blurred or low-resolution image remains blurred even if its resolution tag is changed to 300 DPI.

For a useful result, the source image needs enough real pixels to support the required output dimensions. The processing workflow should then use proportional resizing and only the minimum JPEG compression needed to meet the selected file-size ceiling.

A tool should not:

Add fake ink marks;
Add random noise merely to increase KB;
Sharpen the handwriting artificially;
Whiten or replace the background;
Change brightness or contrast;
Recolour the signature ink; or
Claim that metadata alone guarantees acceptance.

Natural Background Protection

The safest processing workflow uses the pixels present in the original image. It should not intentionally clean, whiten, recolour or redraw the signature.

Aggressive background removal or contrast adjustment can remove faint dots and thin pen strokes. Some loss of detail is unavoidable when a large photograph is reduced to a small JPG, but unnecessary visual enhancement should be avoided.

What a Reliable DPI Checker Should Display

A technically transparent checker should show:

Original pixel dimensions;
Original file format;
Original file size;
Detected horizontal resolution;
Detected vertical resolution;
The resolution unit;
Whether the metadata is missing or conflicting;
Selected output pixels;
Selected output DPI;
Final downloaded file size; and
Verification results after the generated JPEG is read again.

When the input image does not contain reliable DPI metadata, the correct status is DPI metadata unavailable. The tool should not silently assume that every phone image is 72, 96 or 300 DPI.

Private Browser-Based Processing

The crop, resize, JPG conversion, compression and download preparation can be performed locally in a modern browser. This keeps the selected signature on the user’s device during the image-processing workflow.

Downloaded signatures are personal files. Store them carefully, avoid sharing them publicly and upload them only to the intended application portal.

Frequently Asked Questions

What is the SSC GD signature size at 300 DPI?

A 6 × 2 cm image at 300 DPI converts to approximately 709 × 236 pixels after rounding to whole pixels.

Is 708 × 236 also correct?

It is very close to 6 × 2 cm and preserves an exact 3:1 aspect ratio. Because the stated physical dimensions are approximate, small rounding differences can occur. Follow exact pixel values if the application form displays them.

Does 709 × 236 pixels prove that the file is 300 DPI?

No. The pixel dimensions are consistent with approximately 6 × 2 cm at 300 DPI, but the JPEG resolution metadata must be checked separately.

Can changing DPI make a blurred signature clear?

No. Changing metadata cannot restore image detail missing from the original. Use a clearer original photograph or scan.

Why is my 300-DPI JPG larger than 20 KB?

File size depends on the number of pixels, image detail, background texture and JPEG compression. DPI alone does not set the number of KB.

Can I add noise to keep the file above 10 KB?

No. Artificial noise does not improve signature quality and may make the image look altered. Use the clearest original and appropriate processing settings.

Should I remove the complete background?

No. Keep a small natural margin around the handwriting. Background removal can erase faint strokes and may make the result look unnatural.

Can this tool guarantee acceptance by SSC?

No. An independent tool can prepare and check technical image properties, but it cannot control the validation process of an external application portal.

What should I do if the upload still fails?

Compare the actual downloaded format, KB, pixels, crop and alignment with the current application instructions. The SSC signature upload error guide covers additional causes.

Use the 300-DPI Profile Only When Required

The 300-DPI, 6 × 2 cm and 10–20 KB combination should be used when it matches the application instructions you are following. It should not be presented as a permanent requirement for every SSC examination.

Use the tool to prepare and inspect the image, retain the original signature file, and treat the application portal as the final authority.
