About the Image Compressor
Make images smaller for faster web pages, quicker uploads, and email limits. Drop in one image or a whole batch, pick a quality level (and optionally cap the dimensions), and download a compressed JPG or WebP — often 60–90% smaller with little visible difference.
Everything runs in your browser using the HTML canvas, so your images are never uploaded and you don’t need an account. WebP squeezes the most out of most photos; JPG is the universally compatible choice.
How to use it
- 1Add images. Drop in or choose one or many JPG, PNG, or WebP files.
- 2Choose how to compress. Set a quality level, or switch to “Target file size” and enter a limit like 200 KB. Pick a format (Auto, JPG, or WebP) and an optional longest-side cap.
- 3Download. Grab the smaller image, or a single ZIP when you compress a batch.
Frequently asked questions
How does the quality slider work?+
It sets the compression level when re-encoding the image. Lower quality means a smaller file with more visible artifacts; 70–80 usually looks great while cutting size dramatically.
Can I compress to a specific file size?+
Yes. Switch “Compress by” to “Target file size”, enter a limit like 200 KB, and the tool searches for the highest quality that still fits under it. If an image can’t reach the target even at full compression, you’ll be told — capping the dimensions usually gets it there.
Which format should I choose?+
WebP typically produces the smallest files at the same quality and is supported by modern browsers. JPG is larger but opens everywhere. “Auto” uses WebP when your browser can create it, otherwise JPG.
Why did resizing shrink it so much?+
File size scales with the number of pixels. Capping the longest side (e.g. to 1920px) removes pixels you rarely need on the web and is often the biggest saving.
Are my images uploaded?+
No. Compression happens entirely in your browser — your images never leave your device.
Can I compress many images at once?+
Yes. Drop in multiple files and they compress together and download as a single ZIP.
