How to Convert an Image to JPG for Government Forms
Government portals, exam registration forms, and online applications consistently require photos in JPG format with specific file size limits — commonly 20KB, 50KB, or 100KB. A photo taken on a smartphone is typically a 3–6MB HEIC or PNG file that needs to be converted and compressed before it can be uploaded. This guide covers the exact steps.

Check the form's exact requirements
Before converting, note the required format (almost always JPG/JPEG), maximum file size (20KB, 50KB, or 100KB are most common), and any dimension requirements (e.g. 35×45mm, 200×230px). These vary between portals — SSC, UPSC, IBPS, and state government forms each have their own specs.
Convert to JPG if the photo is PNG or HEIC
If your photo is from an iPhone (HEIC) or saved as PNG, upload it to the JPG converter and download the JPG version. The converter fills any transparent areas with white automatically.
Resize to the required dimensions
Use the Image Resizer to set the exact pixel dimensions specified by the form. For passport-size photos: 35×45mm at 100 DPI = 138×177px. For SSC/UPSC: typically 200×230px or as specified in the notification.
Compress to the required file size
Use the Image Compressor to hit the target file size. For a 20KB limit: 200×230px at 65–70% quality. For 50KB: 300×350px at 75%. For 100KB: 400×500px at 80%. Check the output size before downloading.
Verify and upload
Right-click the downloaded file → Properties → check file size. Ensure it is under the limit. Some portals reject files that are even 1KB over — aim for 80–90% of the limit for a safe buffer.
