Frequently Asked Questions

How to resize photos and signatures online for UPSC, SSC, Banking (IBPS/SBI), and Railway exams?

Upload your photo or signature into the resizer and open the "Select Preset" dropdown in Section 1. Choose your exam—such as UPSC Photo (350x350 px), SSC Photo (3.5x4.5 cm), IBPS/SBI Bank Photo (200x230 px), or Bank/SSC Signature (140x60 px). The tool automatically configures the exact pixel or centimeter dimensions, DPI header, and target KB size. Click Apply and download your compliant image right below the button.

How to resize images for websites, YouTube thumbnails, and social media without losing quality?

For social media and web graphics, you can either pick a built-in HD preset—like Instagram/WhatsApp Square (1080x1080 px), YouTube Thumbnail (1280x720 px), or Full HD Web Banner (1920x1080 px)—or enter any custom pixel dimensions. Leave the Target KB box blank, set Manual Quality to 90%, and choose WEBP or JPG format for fast-loading, crystal-clear web images.

Can I resize an image in centimeters (cm), millimeters (mm), or inches with 200, 300, or 600 DPI?

Yes! Change the "Measurement Unit" dropdown in Section 1 to Centimeters (cm), Millimeters (mm), Inches (in), Pixels (px), or Percentage (%). When you select a print resolution like 200 DPI, 300 DPI, or 600 DPI, the tool accurately converts your physical dimensions into pixels and writes the true DPI value directly into the JPEG JFIF binary header for PAN card, passport, and exam portals.

How do I print my Name and Date on a passport photo for SSC, NEET, JEE, or State PSC forms?

In Section 3 ("Rotate, Filter, Format & Name Tag"), check the box labeled "Print Name & Date Strip on Photo". Enter your full name and the date on which the photograph was taken. When you click Apply, the tool automatically generates a clean white nameplate at the bottom of your resized photo with bold black text.

Is this online image resizer completely free and safe for personal photos and signatures?

Yes, WhyTomic Free Image Resizer is 100% free with no signup or watermark. All image cropping, resizing, DPI modification, and KB compression happen locally inside your web browser using HTML5 Canvas—meaning your personal photos, ID cards, and signatures are never uploaded to any external server.
