Quick Reference

  • Cover — fills target exactly; crops edges if needed (best for most cases)
  • Fit — entire image visible; adds white background if needed
  • Stretch — exact target dimensions; may distort proportions
  • Percentage above 100% upscales — useful but pixels can look soft

How to Use the Image Resizer

  1. Drop an image or click to browse.
  2. Pick a mode: Custom Pixels, Percentage, or Social Media preset.
  3. If your target aspect ratio differs from the original, pick a crop mode: Cover (fill and trim), Fit (letterbox), or Stretch.
  4. Choose output format and adjust quality if needed.
  5. Preview updates automatically — click Download when ready.

What's the Difference Between Resizing and Compressing?

Resizing changes the image's pixel dimensions (e.g. 4000×3000 → 1080×1080). Compressing reduces file size at the same dimensions by removing visual data the eye can't detect. Resizing usually reduces file size too, but the goal is dimensional accuracy — useful for social media uploads, web layouts, and platform-specific requirements.

Common Uses for an Image Resizer

  • Social media posts — match exact platform dimensions (Instagram square, Facebook cover, YouTube thumbnail).
  • Website thumbnails — generate consistent product or blog images.
  • Profile pictures — fit avatar squares without distortion.
  • Email signatures — keep images under inline-display sizes.
  • Print preparation — scale up to required print dimensions.
  • Batch uniformity — make all product photos exactly 800×800.

Frequently Asked Questions

What does "Cover" crop mode do?

Cover scales your image to fully fill the target dimensions, cropping edges as needed. The whole target rectangle is filled with image content — no white bars — but you may lose parts of the original near the edges. It's the most common choice for social media.

When should I use "Fit" instead?

Use Fit when you can't afford to lose any part of the image — like a logo, infographic, or screenshot. It shrinks the image to fit entirely inside the target dimensions and pads any leftover space with white.

Can I upscale a small image to a larger size?

Yes — use the Percentage mode and go above 100%, or set custom pixels larger than the original. But quality degrades because there's no real new detail to add; the browser just interpolates pixels. Best results: stay under 200% for upscaling.

Why do my Instagram uploads look bad?

Instagram re-compresses uploads aggressively. To minimize quality loss, upload at the exact recommended size (1080 × 1080 for square posts) in JPEG at 85–95% quality. Our Instagram presets match these recommended sizes.

Does the image resizer work offline?

Yes. Once the page is loaded, all processing runs locally in your browser.
