How to compress an image online

STEP 1

Upload JPG, PNG, GIF, or other supported images from your device.

STEP 2

Adjust quality settings if shown, then compress to shrink the files for web and email.

STEP 3

Download individually or as a ZIP when processing finishes. Each file stays available for up to 5 downloads.

Strong size savings

Reduce photo and graphic file size for faster pages and easier sharing while keeping on-screen detail.

Simple batch workflow

Upload multiple images, compress in one go, and download the results. No desktop editor required.

Free & secure

Works in the browser with encrypted uploads. Files expire after limited downloads.

Best formats after compression

JPG usually wins for photos (smaller files). PNG is better for graphics with sharp edges or transparency. Compress the format you already need for the destination, or use the JPEG/PNG-specific compressors for focused defaults.

Web and email tips

For websites, smaller images load faster and use less bandwidth. For email, compression helps attachments clear size limits. Start with a moderate quality setting and tighten only if the file is still too large.

Will image compression ruin photo quality?

Moderate compression keeps most photos looking sharp on screens. Heavy compression can add artifacts. Use a higher quality setting when the image will be printed or zoomed.

Which image formats can I compress?

JPG, PNG, GIF, and other common web formats are supported. Pick JPEG-specific or PNG-specific compressors when you want format-focused defaults.

Can I compress many images in one batch?

Yes. Upload multiple images within plan limits, compress them together, and download the results.

Is JPG or PNG better after compression?

JPG usually wins for photos (smaller files). PNG is better for graphics with sharp edges or transparency. Compress the format you already need for the destination.
