How to use it

  1. 1Drop an image onto the box, or click to choose a file from your device.
  2. 2Set the quality, an optional max width, and the output format (JPEG, WebP, or PNG).
  3. 3Click Compress, compare the original against the result, and download the smaller file.

Large images slow everything down. Heavy photos make web pages load sluggishly and hurt your search ranking, bump up against the attachment limits on email and contact forms, and bloat the screenshots you paste into docs, tickets, and bug reports. Compressing an image trims that weight so it loads fast, sends cleanly, and stops eating storage — usually with no visible difference in quality.

This tool compresses your image entirely inside your browser using the Canvas API. There is no upload, no server, no watermark, and no account. The file you drop in is decoded, redrawn, and re-encoded locally on your own machine, which makes it safe for private screenshots, client work, and anything you would rather not hand to a website.

You stay in control of the trade-off. The quality slider lets you dial in how aggressively the image is compressed, and an optional max width lets you scale it down — often the single biggest size win, since a 4000px photo rarely needs to stay 4000px wide. Compare the original and the compressed preview side by side and see exactly how many kilobytes you saved before you download.

Pick the format that fits your use. JPEG is the safe default for photos and screenshots and is supported everywhere. WebP usually produces a noticeably smaller file at the same quality and is great for the modern web. PNG is lossless, so it keeps every pixel exact and supports transparency — but the file stays larger and the quality slider has no effect on it.

FAQ

Is this tool free?
Yes — completely free, with no sign-up, no watermark, and no limits. It runs entirely in your browser.
Is my image uploaded anywhere?
No. Everything happens locally using the Canvas API in your browser. The image is never sent to a server — it stays on your device the entire time.
Can I control how much it compresses?
Yes. Use the quality slider to choose the compression level and set an optional max width to scale the image down. The compressed preview and new file size update so you can find the right balance before downloading.
Which formats can I export to?
JPEG, WebP, and PNG. JPEG is the universal default, WebP is usually the smallest at the same quality, and PNG is lossless with transparency support (quality has no effect on PNG).
Does it work offline?
Yes. Once the page has loaded, compression runs entirely on your device, so it keeps working even if you go offline.
