Resize Image Online — Exact Dimensions, No Quality Loss

How to resize an image (3 steps)

1. Choose your image. Click the box or drag a file in. Its current dimensions appear immediately.
2. Set the new size. Type an exact width or height (the other adjusts automatically when "Keep ratio" is on), or use the quick 25/50/75/100% buttons.
3. Download. The result is re-rendered with high-quality smoothing and saved at the size you chose.

When to resize instead of compress

Compression shrinks a file without changing its dimensions — good when the pixels are already right. Resizing changes the actual width and height — necessary when a platform demands exact specs (a 1200×630 social image, a 512×512 app icon, a 1920×1080 slide). If a site says "max 1000 px wide", resizing is the only fix that works.

FAQ

• Does resizing lower the quality? Scaling down never loses visible quality. Scaling up interpolates new pixels, so the image will look slightly softer — avoid enlarging beyond the original size.
• Why keep aspect ratio on? Turning it off lets you stretch an image into a box that distorts it. Keep ratio on for anything people will look at closely.
• Is this free and private? Yes — resizing runs in your browser. No upload, no watermark, no size limits.
