Image Resizer

Q: 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 with no bars, but you may lose parts near the edges. It's the most common choice for social media.

Q: 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 and pads leftover space with your chosen background color.

Q: Can I upscale a small image to a larger size?

Yes, use Percentage mode above 100% or set custom pixels larger than the original. Quality degrades because there's no real new detail to add. Best results stay under 200%.

Q: How does compress to target size work?

Enable it and enter a KB limit; the tool auto-tunes JPEG or WebP quality to land just under that size. PNG is lossless so the target is ignored.

Resize images to exact pixels, scale by percentage, or pick from 15+ social media presets. Smart crop modes, compress-to-target-size, and live preview — 100% browser-based.

Quick Reference

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

🔒 All resizing happens in your browser. Your image never leaves your device.

How to Use the Image Resizer

Drop an image or click to browse (JPG, PNG, WebP, GIF, AVIF).
Pick a mode — Custom Pixels, Percentage, or a Social Media preset.
Choose a crop mode if your target aspect ratio differs: Cover (fill & trim), Fit (letterbox), or Stretch.
Set output — format, quality, an optional target file size, and a background color for padding/transparency.
Preview updates live — then Download or Copy 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 uploads, web layouts, and platform-specific requirements. This tool does both: resize to your target, then optionally compress to a maximum KB size.

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 bars — but you may lose parts 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 and pads leftover space with your chosen background color.

Can I upscale a small image to a larger size?

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

How does "compress to target size" work?

Enable it and enter a KB limit; the tool auto-tunes JPEG/WebP quality to land just under that size. PNG is lossless so the target is ignored — choose JPEG or WebP for size targets.

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 sizes.

Does the image resizer work offline?

Yes. Once the page is loaded, all processing runs locally in your browser — nothing is uploaded.
