Image Compressor

Re-encode images with adjustable quality, format, and size. JPEG and WebP give the biggest savings; PNG is lossless, so its savings come mainly from resizing.

About the Image Compressor

Shrink images for the web, email, and messaging apps. Choose the output format, quality level, and an optional maximum dimension, and see exactly how much space you saved.

Compression is honest and local: files are re-encoded by your browser, the real savings are reported, and if a file cannot be made smaller the tool says so instead of pretending.

Frequently asked questions

Which output format makes the smallest files?expand_more

WebP usually produces the smallest files, followed by JPEG. PNG is lossless and best for graphics with sharp edges, but it is often larger.

Why did my image not get smaller?expand_more

It was probably already well optimized. Try a lower quality setting, a smaller maximum dimension, or switching to JPEG or WebP.

Can I compress multiple images at once?expand_more

Yes — select several files and each one is compressed and listed for download separately.
