Image Compressor
About Image Compressor
Shrink image file sizes so your pages and emails load faster, without noticeably degrading quality. Load a JPEG, PNG, or WebP and adjust the compression level to balance size against sharpness — the before/after preview lets you see the result before downloading. Compressing images for the web improves Core Web Vitals, reduces bandwidth, and speeds up uploads. Everything runs locally in your browser, so original images are never uploaded and you can compress unpublished or sensitive artwork safely.
How To Use
- Load an image from your device — JPEG, PNG, or WebP — or drag and drop it in.
- Adjust the compression level and compare the before/after preview.
- Download the smaller image when the balance of size and quality looks right.
Example
Input: A 2.5 MB photo headed for a website hero section.
Output: A compressed JPEG around 300–400 KB with no visible drop in quality.
Who Uses Image Compressor
- Designers and creators who want private image tools (crop, compress, convert).
- Anyone processing local photos without ever uploading them.
- People who want private — files and text stay on your device and are never uploaded to a server for images.
Frequently Asked Questions
How much can I compress an image without losing quality?
Most photos can be compressed to 30–50% of their original size before the loss becomes visible. Use the before/after preview to find the smallest size that still looks good to you.
Which formats are supported?
JPEG, PNG, and WebP. JPEG and WebP use lossy compression for photos; PNG is lossless and best for graphics with sharp edges or transparency.
Why should I compress images for the web?
Smaller images load faster, which improves Core Web Vitals and SEO, reduces bounce rate, and saves bandwidth for you and your visitors.
Is my image uploaded anywhere?
No. Compression runs entirely in your browser, so private and unpublished images never leave your device.
