Image Resizer
Upload an image and resize it to exact width/height — with aspect ratio lock. The photo never leaves your browser.
How to use — Image Resizer
- Select or drag-drop an image — its current size fills the fields automatically.
- Pick a mode: By Size (enter exact width/height in px, cm, mm or inches), As Percentage (scale to 25%, 50% etc.), or Presets (passport photo, SSC exam, Instagram, YouTube and more).
- Choose the output format (keep original, or convert to JPG/PNG/WEBP) — and optionally set a target file size in KB (e.g. 50 KB for exam uploads).
- Click Resize image, check the preview and sizes, then download.
FAQ
Is the photo uploaded anywhere?
No — resizing happens on a canvas in the browser. The photo never leaves your device, which also makes it safe for documents like passport or exam photos.
How do I get a photo under a specific KB limit (for exam forms)?
Enter the limit in "Target File Size" (e.g. 50 for SSC's 20-50KB photo rule) and choose JPG output. The tool automatically adjusts compression to get as close as possible under that size — no trial and error needed.
What are the common Indian exam photo sizes?
Passport photo: 600×600 px (2×2 inch at 300 DPI). SSC: photo 200×230 px (20-50 KB), signature 140×60 px (10-20 KB). PAN card: 213×213 px. All of these are in the Presets tab — but always double-check your exam's current notification, as requirements can change.
When should I use cm/mm/inch instead of pixels?
When a form asks for a physical size (like "3.5cm × 4.5cm photo"). Choose the unit and a DPI — 300 DPI is the standard for printed documents. The tool converts it to exact pixels for you.
What does aspect ratio lock do?
Changing the width automatically adjusts the height proportionally (and vice versa) — so the photo isn't stretched. Turn it off (or use a Preset) when a form demands exact dimensions that don't match your photo's shape.
Which output format should I choose?
JPG for photos and exam uploads (smallest, universally accepted), PNG for graphics/screenshots needing sharp text or transparency, WEBP for websites (best compression). "Original" keeps whatever format you uploaded.
Will quality suffer when enlarging an image?
Yes — enlarging beyond the original (upscaling) causes blur since new pixels must be invented. Shrinking always stays sharp.
