- Choose up to 20 images.
- Choose format, quality and an optional size target. Allow downsizing if needed.
- Compare actual sizes and previews, then save individual files or a ZIP.
When to use Compress image
Prepare a photo for email or a website. Compare the original and exported byte counts. If the result is larger, lower quality or try WebP rather than repeatedly recompressing the output.
Supported formats and limits
JPG / PNG / WebP. 20 images, 20 MB each, 50 MB total and 16 megapixels per image. Some targets cannot be reached without resizing or losing detail. JPG flattens transparency to white; animation and metadata are omitted.
Practice meeting an upload requirement
Use the image upload walkthrough and our owned 960 × 640 graphic to compare dimensions with file-size limits. Targets use actual encoded bytes; quality alone may not reach a requested size.
About this tool
Can I ask for an image under 100 KB?
Yes. Open Target file size and enter 100. The result reports actual bytes and whether it reached the target. If it cannot, change format or dimensions, or explicitly allow downsizing. PNG quality is not adjustable.
Does the target replace my original?
No. Up to 20 selected images are processed in order into separate exports. Several successful outputs download together in a ZIP. An unattainable target is labelled rather than treated as success.
What should I inspect before sharing the compress image output?
20 images, 20 MB each, 50 MB total and 16 megapixels per image. Some targets cannot be reached without resizing or losing detail. JPG flattens transparency to white; animation and metadata are omitted. Download the output and open it in the receiving application. A browser download request does not confirm that saving finished.
