Frequently asked questions

How do I resize an image to 20 KB or 50 KB?

Enter your target (e.g. 20) in the "Target file size (KB)" field, choose JPG format, and click Resize. The tool automatically finds the best quality that fits under your target — perfect for SSC, UPSC, PAN card and other government form uploads.

How do I resize a photo without stretching it?

Keep the "Lock aspect ratio" box checked. When you change the width, the height updates automatically so the photo never looks stretched or squashed.

Does resizing reduce image quality?

Making an image smaller keeps it sharp. Enlarging beyond the original size cannot add detail, so the result may look soft. For best quality, only downscale.

Is my photo uploaded to a server?

No — resizing happens entirely in your browser using the Canvas API. Your photo never leaves your device.

What sizes do government forms usually need?

Common requirements: photo 20–50 KB (about 200×230 px) and signature 10–20 KB (about 140×60 px). Use the target-KB field together with exact pixel dimensions to satisfy both rules at once.
