Free Image Compressor

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.
