Why Do Portals Demand .JPG Instead of .JPEG?
If you have ever tried applying for government recruitments (such as SSC CGL, CHSL, UPSC Civil Services, State Police, Railway RRB, or IBPS Bank exams), you may have encountered the frustrating error: "Invalid image file format. Only .jpg files are allowed."
While JPEG and JPG are scientifically identical image encoding formats developed by the Joint Photographic Experts Group, many backend form validation scripts rely on strict file-extension patterns (e.g., regex checking strictly for \.jpg$). If your smartphone, digital camera, or image editor exported your photograph with the four-letter extension .jpeg, the server rejects it.
SizeSnap solves this instantly. By rendering your image through client-side HTML5 canvas technology, it generates a standard JPEG stream with the exact image/jpeg MIME type and the universally compliant .jpg extension.

Frequently Asked Questions (FAQ)
What is the difference between JPEG and JPG?▾
Technically, there is zero difference in image data or compression between JPEG and JPG. Both use the exact same Joint Photographic Experts Group raster compression algorithm. The only difference is the file extension: older Windows systems (MS-DOS) required 3-letter extensions (.jpg), whereas Macintosh and Unix systems used 4 letters (.jpeg). Today, modern systems treat them identically, but rigid upload portals still specifically demand .jpg.
Why do government job and exam portals reject .jpeg files?▾
Many official submission systems (such as SSC, UPSC, State PSCs, IBPS, and University admissions) use rigid file verification scripts that specifically check if the uploaded filename ends with ".jpg". If your phone or camera saved the file as ".jpeg" or ".jfif", the portal throws an error like "Only .JPG format allowed". SizeSnap standardizes the file header and extension to .jpg so your application uploads without errors.
Does converting JPEG to JPG degrade picture quality?▾
No. When converting with SizeSnap, quality is preserved at up to 100% loss-free precision. Your original pixels, sharpness, and clarity remain intact without visible compression artifacts.
Can I convert .jfif and .png files to .jpg as well?▾
Yes! Windows often downloads images from Google Chrome with the .jfif extension. SizeSnap automatically recognizes .jfif, .jpeg, .png, and .webp files and converts them into standardized .jpg format in seconds.
Is it safe to convert my private ID documents and passport photo here?▾
100% safe. Unlike traditional conversion websites, SizeSnap does all processing locally inside your device using HTML5 Canvas API. Your photos and sensitive ID proofs are never uploaded to any server or third party.
