How to Resize a Photo to Exact Dimensions Online — Free

PhotoFit Guide · August 2026 · 5 min read

Every government exam portal, passport application, and job portal specifies an exact photo size in pixels — and getting it wrong means rejection. Here is a complete guide to resizing any photo to exact pixel dimensions in under a minute, for free, without installing any software.

Why does photo dimension matter?

Government portals validate photo dimensions before accepting your application. A photo that is 210×230 px when the portal expects 200×230 px will be rejected outright. The same applies to passport photo agencies, corporate HR systems, and social media profile uploads.

File size (KB) and pixel dimensions are two different things. Compressing a photo to 40 KB does not change its width and height in pixels — you need a dedicated resize step.

Step-by-step: Resize a photo using PhotoFit

Open PhotoFit

Go to photofitapp.in in any browser — Chrome, Safari, Firefox. No account, no download required.

Click the Resize & Compress tab

The hero tool on the homepage compresses to KB. Switch to the "Resize & Compress" tab to set pixel dimensions.

Enter your target dimensions

Type the width and height in pixels. For example, 200 in the Width field and 230 in the Height field for most Indian exam portals.

Set a KB target (optional)

Most portals require both a pixel size and a KB limit. Enter the maximum KB in the file size field — e.g., 50 for a 50 KB limit.

Upload your photo

Click Upload or drag-and-drop. JPG, PNG, and WebP are supported. Your photo stays on your device.

Download the resized photo

Click Download. The file is ready for upload to any exam, passport, or job portal.

Tips for getting the best result

Always start from the highest-resolution original you have. Downsizing preserves quality; upsizing creates blur.
For passport and ID photos, make sure your face is centred before resizing — cropping after ruins the proportion.
If the portal requires both a pixel size and a KB limit, set both in PhotoFit's Resize & Compress tab at the same time.
For exam portals that reject PNGs, use JPEG output. PNGs are larger and the portal may not accept them.
Save a copy of the original file. Compressed and resized files cannot be restored to full quality.
