About the Image Compressor
This tool re-encodes a photo as JPEG or WebP at a quality level you control, trading a little visual fidelity for a much smaller file. Smaller images load faster on web pages, attach more easily to email, and use less storage. The before-and-after byte counts let you see exactly how much you saved at the quality you picked.
How to use it
- Load your image.
- Choose the output format - JPEG for photos, WebP for better compression at the same quality.
- Drag the quality slider and watch the estimated file size update.
- Download once the size and look are a good balance.
Quality around 70 to 80 percent is the usual sweet spot: most people cannot tell it from the original, but the file is far smaller. Both JPEG and WebP are lossy, so detail removed during compression cannot be recovered - keep your original if you may need it later. Re-compressing an already compressed JPEG can stack artifacts, so start from the best source you have. Compression runs in your browser, so the image is never uploaded.
Frequently asked questions
What quality setting should I use?
For most photos, 70 to 80 percent gives a large size reduction with little visible loss. Drop lower for thumbnails where small artifacts do not matter, and stay higher for images with sharp text or fine gradients.
Should I pick JPEG or WebP?
WebP usually produces a smaller file than JPEG at the same perceived quality and supports transparency, and it is supported by all modern browsers. Choose JPEG when you need maximum compatibility with older software.
Can I get my original quality back after compressing?
No. JPEG and WebP are lossy, so the detail discarded during compression is gone. Keep a copy of the original file if you might need full quality again.
Does compression upload my image to a server?
No. The image is re-encoded locally in your browser, so the file never leaves your device.
