Compress Images Online

Shrink JPG, PNG, and WebP file sizes — all in your browser.

or drag and drop

How It Works

Image compression rebuilds your pictures at a lower quality or target file size using the canvas API in your browser. Pixels are read from your files locally, re-encoded (for example as JPEG at a chosen quality), and saved for download—so thumbnails, product shots, and personal photos are not uploaded to our servers for this step.

How to Use

Add one or more images on the Compress tab (JPG, PNG, WebP, and other supported formats).
Set quality (1–100) with the slider, and optionally enter a target size in KB for tighter limits.
Click “Compress” to process all selected images and wait for the progress bar to finish.
Download one file or a ZIP when several images were processed.

Common Use Cases

Shrinking photos before attaching them to email or school portals.
Meeting upload limits on job sites, marketplaces, or CMS media libraries.
Reducing banner and hero images so web pages load faster.
Batch-processing screenshots so shared folders use less storage.

FAQ

Will compressing ruin my image quality?: Lowering quality removes fine detail and can show JPEG artifacts near edges and gradients. Start near 80% quality for photos; increase if you see banding, or decrease if you only need a small preview. PNG-to-JPEG compression changes format and can affect transparency.
Is it safe to compress images online here?: Compression runs in your browser: files are not sent to our servers for encoding. Still follow your organization’s rules for confidential images, and avoid processing on shared devices without clearing downloads afterward.
Why is my compressed file still big?: Very large dimensions or complex PNGs may stay large until you also resize dimensions or switch to a more efficient format (for example WebP). Some images are already heavily compressed, leaving little room to shrink further.
