Why use our Image Compressor?
Our image compressor is built for speed and privacy. It runs entirely in your browser so images never leave your device unless you explicitly choose server features. That means faster results, better privacy, and no waiting in upload queues.
Key benefits
- Privacy-first: Default client-side compression — we do not upload your files.
- High quality: Adjustable quality settings let you balance size and visual fidelity.
- Multiple formats: Supports JPG, PNG and WebP and can output smaller JPG or WebP files.
- Batch processing: Compress multiple images at once for bulk optimization.
- Mobile friendly: Works well on phones and tablets — use the Web Share API to share results on mobile.
How it works — quick steps
- Upload or drag & drop: Add one or many images into the compressor box.
- Choose quality: Use the quality slider to preview file size and image appearance.
- Compress: Click the compress button and wait for the browser to re-encode the image(s).
- Download: Download compressed images or use the share button on mobile.
Best practices to get the smallest images
- Prefer WebP output for photographic images — it often gives the best size/quality ratio.
- Cropping large unused areas of an image before compression reduces final size.
- For screenshots or simple graphics, lower quality values typically keep acceptable results with big savings.
- Batch compress photos with similar settings to speed up workflow.
Common use cases
- Prepare photos for faster website uploads or CMS publishing.
- Shrink images for email attachments to meet size limits.
- Optimize images for social sharing without losing look and feel.
- Reduce storage usage on devices before backups.
Frequently Asked Questions
Is compression done on my device or uploaded to a server?
By default compression runs in your browser so your files are not uploaded. If we offer server features, they will be opt-in and clearly labeled.
Which image formats are supported?
This tool supports JPG, JPEG, PNG and WebP. You can choose output format and quality per image.
Will compression reduce visible image quality?
You control a quality slider to balance file size and image fidelity. Medium settings often provide significant size reductions with minimal visible change.
