Resize Passport & Visa Photos to 50 KB / 2x2 Inches
Government portal requirements (e.g. US Passport, Schengen Visa, Indian OCI, DV Lottery) demand strict 2x2 inch (600x600 px) dimensions and sub-50 KB file sizes. Our target KB slider hits the mark automatically.
Social Media Dimension Presets
Easily resize images for YouTube banners (2560x1440), LinkedIn banners (1584x396), Twitter/X headers (1500x500), and Instagram posts (1080x1080) with locked aspect ratio.

Why 300 DPI is essential for physical print while 110-150 DPI is ideal for web uploads and forms.
Frequently Asked Questions
Everything you need to know about browser processing, file safety, and format capabilities.
How do I resize an image to exactly 50 KB for an online portal?
Enable the 'Target Size' option in the studio controls, enter '50', and our engine will iteratively adjust compression and dimension scaling to meet the exact file size threshold.
Does resizing decrease image sharpness or cause pixelation?
Downscaling maintains high fidelity via Bicubic smoothing. Upscaling small images significantly beyond their original resolution will naturally stretch existing pixels, so we highlight scaling percentage in real time.
Can I lock the aspect ratio so my photo does not stretch?
Yes. The aspect ratio lock is enabled by default. Changing the width automatically calculates the proportionate height to prevent distortion.
Are my personal photos sent to any server or AI model?
Never. Images are processed strictly on your computer's GPU/CPU canvas. No image data is ever transmitted over the network.
