Why compress an image?

Image compression reduces the amount of data required to store or deliver an image. It can help with email attachments, website uploads, cloud storage and forms with file-size limits. The best setting depends on the source image and how the result will be used.

Simple workflow

Choose your input, set relevant options and start processing.

Real processing

The page waits for the actual backend job rather than inventing completion.

Review first

Keep the original and check the output before relying on it.

Important limitations

Results depend on source quality and the production processing engine.
Format-specific features may not survive every workflow.
Actual production limits are enforced by the backend; this page does not invent them.
Keep your original until the result has been checked.

Frequently asked questions

Will compression reduce quality?

It can. Stronger compression generally increases the file-size reduction but may introduce visible artefacts, especially with lossy formats.

Can I compress several images?

Yes, multiple files can be selected and submitted as one batch where the backend supports it.

Is PNG compression always smaller?

Not necessarily. PNG is lossless, and some images compress much better than others.

Is JPG good for photographs?

JPG is commonly efficient for photographs because it uses lossy compression.

Can I compress images for a website?

Yes. Smaller appropriately sized images can reduce transfer size and improve page-loading performance.

Does compression change image dimensions?

Not necessarily. Compression and resizing are separate operations, although a backend may offer both as a combined workflow.

Can I compress images on mobile?

Yes. The interface is designed for modern mobile browsers.

Will metadata be preserved?

Metadata preservation depends on the output format and processing implementation.

Can I compress without losing quality?

Lossless processing can avoid additional visual loss, but the achievable size reduction varies by image.

How do I choose a compression level?

Start with Recommended and inspect the result. Use stronger compression when file size matters more than visual fidelity.
