✦ Free Online Image Compressor
Compress JPEG, PNG & WebP Images Without Losing Quality
Large photos slow down websites, fill up storage, and make emails bounce.
This free online image compressor shrinks JPEG, PNG, WebP, GIF and BMP files —
often by 50-90% — while letting you control exactly how much quality you keep.
No software to install, no account to create, and no watermark on your downloads.
Everything runs locally in your browser, so your files are never uploaded anywhere.
Drop a PDF instead of images and its pages are converted automatically, ready to compress
and re-export as a PDF or ZIP.

Frequently Asked Questions
Is this image compressor really free?
Yes. Compressing images is 100% free, with no sign-up, no watermarks, and no daily limits. There's no hidden premium tier.
Will compressing my images reduce their quality?
You control the quality level yourself, so you decide the trade-off between file size and visual quality. At quality 75-85%, most JPEG and WebP images look visually identical to the original while being significantly smaller.
Which image formats can I compress?
JPEG, PNG, WebP, GIF, and BMP are all supported. You can also drop a PDF — its pages are automatically converted to images first, which you can then compress and re-export as a PDF or ZIP.
Can I convert the image format while compressing?
Yes. Set the Output Format option to JPEG, PNG, or WebP to convert every uploaded image to that format as part of the compression step.
Is there a file size limit?
Each file can be up to 50 MB, and there's no limit on how many images you upload in a batch — your device's memory is the only real constraint.
Are my images uploaded anywhere?
No. Everything runs locally in your browser using JavaScript — your files are never uploaded, stored, or sent to any server.
Can I compress multiple images at once?
Yes, batch compression is fully supported. Upload as many images as you need, tune the settings once, and compress or download them all together as a ZIP.
