Why Use This Tool

Whether you need a 400×400 profile picture, a 1200×630 social media banner, or a specific pixel size for a form upload, this tool lets you set the exact dimensions and download instantly. No Photoshop, no GIMP, no app installs.

Two resize modes give you full control. Aspect ratio lock scales your image proportionally so nothing gets distorted — perfect for photos. Exact dimensions mode stretches the image to fill your specified size precisely — useful when a portal requires an exact pixel match.

Choose between JPG output (smaller files, adjustable quality) or PNG output (lossless, supports transparency). Everything runs in your browser — your image never leaves your device.

Frequently Asked Questions

Maintaining aspect ratio scales the image proportionally so it fits within your target size without distortion — if you set 800×600 on a 4:3 image, it fits perfectly, but a 16:9 image would be scaled to 800×450 instead. Exact dimensions mode stretches the image to fill the precise width and height you set, which may distort the image if the ratio doesn't match.
Use JPG for photographs and images with many colors — it produces smaller files with adjustable quality. Use PNG for images with text, logos, screenshots, or transparency — it preserves sharp edges and supports transparent backgrounds. JPG does not support transparency.
This tool handles images up to 50 megapixels, which covers virtually any phone camera or DSLR photo. Very large images are pre-scaled in memory to prevent browser slowdowns. All processing happens in your browser — no file is uploaded to any server.
