JPG, PNG, WebP · up to 30 images · you can also paste with Ctrl+VWhat does this image compressor do?
This free image compressor re-encodes your photos with a smarter quality setting so they take up far less storage while looking the same on screen. A typical smartphone photo of 3–5 MB usually drops to 300–800 KB, which makes pages load faster, emails send without bouncing and uploads finish on slow connections.
Compression happens entirely inside your browser using the HTML5 Canvas API. There is no upload, no queue and no server copy of your images, so it is safe for personal photos, ID scans and unreleased product shots.
How to compress an image
- Add your images. Drag them onto the box above, click to browse, or paste a screenshot with Ctrl+V. You can add up to 30 files at once.
- Choose a quality level. 75% is a safe default. Go lower for thumbnails, higher for photography portfolios.
- Pick an output format. Keep the original format, or switch to WebP for the smallest files that every modern browser supports.
- Optionally set a maximum width. Website images rarely need to be wider than 1920 pixels; scaling down saves even more space.
- Click Compress images and download each file, or grab all of them in one ZIP.
Features and benefits
- Batch processing: compress dozens of images in one go and see total savings.
- Three formats: JPEG, PNG and WebP input, with JPEG or WebP output for maximum savings.
- Smart safeguard: if a file is already optimised and would get bigger, the original is kept automatically.
- Resize while compressing: set a maximum width to cut size dramatically for web use.
- Privacy by design: no uploads, no accounts, no watermarks and no daily limits.
Which format should you choose?
| Format | Best for | Notes |
|---|---|---|
| WebP | Websites, blogs, online stores | Usually 25–35% smaller than JPEG at the same visual quality. Supported by all current browsers. |
| JPEG | Photos for email, documents and older software | The most compatible format. Does not support transparency. |
| PNG | Logos, screenshots with text, transparent graphics | Lossless, so files stay larger. Convert to WebP if transparency is needed with a smaller size. |
Common use cases
- Speeding up a WordPress or Shopify site and improving Core Web Vitals.
- Meeting upload limits on job portals, visa forms and university applications.
- Sending holiday photos by email or WhatsApp without hitting attachment limits.
- Preparing product images for marketplaces such as Amazon, Daraz or Etsy.
- Saving storage space on your phone, laptop or cloud drive.
Tip: compress after you have finished editing. Repeatedly re-saving the same JPEG lowers quality each time, so keep an untouched original. Want the full background? Read our guide on how to compress images without losing quality.
Frequently asked questions
Is this image compressor really free?
Yes. There are no paid plans, watermarks or limits on how many times you use it.
Are my images uploaded to your server?
No. All processing happens on your own device in the browser. Closing the tab removes everything.
How much can I reduce an image’s size?
Photos typically shrink by 50–80% at 75% quality. Results depend on the original: images that are already compressed will shrink less.
Will compression remove EXIF data such as location?
Yes. Re-encoding through the canvas strips metadata such as GPS location and camera details, which is good for privacy when sharing photos online.
Why did my PNG get bigger?
PNG is a lossless format, so the quality slider has no effect on it. Choose WebP or JPEG as the output format to make PNG images much smaller.
