One workspace for both GDS image requirements
Switch between the two India Post GDS image types without searching for separate size, format, DPI, and file-size settings.
Photo and signature presets
Use one GDS workspace for the 320x400 px photo and the 300x120 px signature, with each tab applying its own fixed dimensions and upload limits automatically.
Correct KB range for each file
Photo output stays within 30-100 KB while Signature output stays within 20-100 KB, so switching tabs also switches the file-size rule used for encoding.
JPG/JPEG output by default
Both document types export as JPG/JPEG, removing an extra format decision and helping you avoid preparing a correct crop that the application portal cannot accept.
Preset-specific crop shape
Photo uses a portrait 4:5 frame while Signature uses a wide 5:2 frame, and the crop target updates as you switch tabs without stretching the source image.
Supported DPI without extra controls
The GDS presets keep a supported DPI value in the JPEG while hiding unnecessary manual controls, so the workflow stays focused on framing and downloading.
Keep the uploaded source while switching
When an image is already open, changing from Photo to Signature keeps the source in the editor and refreshes the target frame, letting you adjust instead of re-uploading.
Prepare GDS photo and signature in three steps
Choose the document type first, review its fixed requirements, then frame and download the image.
Choose Photo or Signature
Select the tab for the file you are preparing and confirm the dimensions, KB range, format, and DPI shown under Required Output.
Upload and adjust the crop
Open the source image, then move or zoom it inside the 4:5 photo frame or 5:2 signature frame until the important content is visible.
Resize and save the result
Create the JPG with the active preset, let ResizeBox fit the file-size range, and save the finished image from the download page.
Prepare both GDS application images
Use the Photo and Signature tabs to apply the right GDS preset, review each crop, and create upload-ready JPG files without manual sizing.
India Post GDS photo and signature questions
Review how the two presets differ, what stays fixed, and how switching tabs affects an image you already uploaded.
This page combines the two image files used by the current GDS application workflow: a 320x400 px Photo and a 300x120 px Signature. Use the tabs to switch between them; each selection updates the required output shown beside the editor.
Photo uses 320x400 px, a 4:5 portrait crop, and a 30-100 KB file range. Signature uses 300x120 px, a 5:2 wide crop, and a 20-100 KB range. Both produce JPG/JPEG files for upload and use the supported 72-150 DPI range.
No. The page remains a single-image tool. Prepare one file, download it, then switch to the other tab and upload or reuse a source as needed. There is no combined upload queue, ZIP package, or requirement to complete Photo and Signature together.
The uploaded source stays in the editor. ResizeBox changes the target dimensions, file-size rule, button label, and crop frame for the newly selected document type, then clears the previous processed result so the next download uses the new preset.
The editor can keep the same source when you switch tabs, but a portrait and a handwritten signature are different documents. Normally, download the photo result, then replace the source with your signature image before preparing the signature file.
No. The source remains unchanged on your device. Switching presets only changes the browser-side crop and output settings used for the next processed result, so you can return to another tab or replace the image without altering the original file.
This workflow is designed around fixed GDS requirements rather than free-form resizing. Hiding those controls reduces accidental changes to dimensions, JPEG output, DPI, or compression rules while still leaving crop and zoom available for framing.
Yes. This page follows the current GDS photo and signature specifications used for these presets, but recruitment portals can revise upload rules. Compare the downloaded files with the live application instructions before final submission.
