About Image Compressor
Free online image compressor that runs locally in your browser. Compress JPG/PNG/WebP with no uploads — fast, private, and great for web, email, and forms.
How it works
How it works
- 1 Add images (drag & drop or click Select from computer).
- 2 Choose output format (keep original / JPG / PNG / WebP) and adjust quality in Settings.
- 3 Optional: set Max Dimension to downscale large images for smaller file sizes.
- 4 Click Process Images and download results (ZIP for multiple files).
Tips
- For “compress image to 100KB/200KB”, lower quality gradually and also reduce dimensions.
- Use WebP for websites to keep good quality with smaller size (if your target supports it).
- Use JPG for photos, PNG for logos/graphics or when you need transparency.
- If the file is still large, downscale first — size drops dramatically on huge images.
FAQ
Are my images uploaded?
No. Everything runs locally in your browser — your files never leave your device.
Does it support batch compression?
Yes. Add multiple images and download as a ZIP.
How can I compress to a specific size (e.g. 100KB)?
Reduce quality first, then reduce dimensions (Max Dimension). Repeat until you reach your target.
Which formats work best for compression?
JPG/WebP are best for photos. PNG is lossless and may be larger for photos.
