# Free Image Compressor

Fast, free image compressor to reduce image file size with a quality slider, real-time preview, and bulk compression—processed locally in your browser.

## Why Use

**Stop oversized images from slowing everything down.**

If your website feels heavy, your blog images take forever to load, or your ecommerce product photos hurt Core Web Vitals, an **image compressor** (aka **image size compressor / online image compressor**) is the quickest fix—no Photoshop, no exports, no guesswork.

**Compress images without sacrificing what matters.**

This **photo compressor** is built for the real tradeoff: smaller file size while keeping strong visual quality. You control compression with a **10–100% quality slider**, so you can tune for speed (web), clarity (social), or fidelity (print).

**Batch speed + privacy by design.**

Need to compress 10–20 images at once for a product launch or campaign? This **bulk image compressor** supports batch processing and runs **client-side in your browser**, meaning your images aren’t uploaded to a server. Compress, preview, download—done.

## How to Use

### **Upload images**

Drag & drop files into the upload area, or click to select from your device. (Supports **JPEG / PNG / WebP** input.)

2. **Set compression quality (10%–100%)**

For each image, move the **quality slider** to control size vs clarity. Use the preview to check details (text edges, logos, gradients, skin tones).

3. **Download compressed images**

Click download to compress and save your optimized files instantly.

### Best-practice presets

- **Website / blog images:** start at **30–60%** to reduce loading time.
- **Photos (general):** **60–80%** is usually the sweet spot for a photo compressor.
- **Print / high fidelity:** use **90%+** if you must preserve fine detail.

Tip: keep the same quality setting across a batch to maintain consistent visual style.

### Common use cases

- **Website image optimization** (faster pages, better UX)
- **E-commerce product photos** (lighter galleries, faster checkout pages)
- **Social media publishing** (quicker uploads, fewer platform re-compressions)
- **Email attachment compression** (avoid “file too large”, faster sending)
- **Mobile app assets** (smaller package size, faster loading)

## FAQ

**Q1: Why does quality drop after I compress images?**

A: Image compression reduces file size by removing some color/detail information. Use moderate settings (e.g., 60–80%) to balance size and clarity.

**Q2: What’s the maximum image size supported?**

A: Processing runs in your browser; large images depend on device performance. For smoother use, keep single files under ~50MB.

**Q3: Is this online image compressor secure—are my files uploaded?**

A: No. It uses **client-side processing**; images are processed locally in your browser and not uploaded to a server.

**Q4: Can I restore the original image after compression?**

A: Compression is irreversible—keep a backup of originals if they’re important.

**Q5: Why did my PNG background become white?**

A: Output is JPEG, which doesn’t support transparency, so transparent areas become white.

**Q6: Can I compress images in bulk?**

A: Yes—this bulk image compressor supports up to **20 images per batch**.
