How to compress an image online
- Upload a JPG, PNG or WebP picture.
- Drag the quality slider until the file is small enough — the preview and size update live.
- Pick a format and download. JPG and WebP give the smallest files.
Why compress images?
Smaller images load faster on websites, attach more easily to emails, and fit inside upload limits. This compressor re-encodes your photo right in the browser, so nothing is uploaded and there are no size caps.
JPG vs WebP vs PNG
JPG is best for photos and gives the smallest size. WebP is a modern format with great quality-to-size and is supported by all current browsers. PNG is lossless — use it when you need a transparent background (try the background remover first).
Frequently asked questions
Will compressing reduce image quality?
You control it with the quality slider. Around 70–80% usually shrinks the file a lot while staying visually identical.
Is there a file size limit?
No. Because compression happens in your browser there are no upload limits and nothing is sent to a server.
Which format gives the smallest file?
JPG and WebP produce the smallest files for photos. Use PNG only when you need transparency.
